How to install pip with Python 3?

edit: Manual installation and use of setuptools is not the standard process anymore.

If you're running Python 2.7.9+ or Python 3.4+

Congrats, you should already have pip installed. If you do not, read onward.

If you're running a Unix-like System

You can usually install the package for pip through your package manager if your version of Python is older than 2.7.9 or 3.4, or if your system did not include it for whatever reason.

Instructions for some of the more common distros follow.

Installing on Debian (Wheezy and newer) and Ubuntu (Trusty Tahr and newer) for Python 2.x

Run the following command from a terminal:

sudo apt-get install python-pip 

Installing on Debian (Wheezy and newer) and Ubuntu (Trusty Tahr and newer) for Python 3.x

Run the following command from a terminal:

sudo apt-get install python3-pip

Note:

On a fresh Debian/Ubuntu install, the package may not be found until you do:

sudo apt-get update

Installing pip on CentOS 7 for Python 2.x

On CentOS 7, you have to install setup tools first, and then use that to install pip, as there is no direct package for it.

sudo yum install python-setuptools
sudo easy_install pip

Installing pip on CentOS 7 for Python 3.x

Assuming you installed Python 3.4 from EPEL, you can install Python 3's setup tools and use it to install pip.

# First command requires you to have enabled EPEL for CentOS7
sudo yum install python34-setuptools
sudo easy_install pip

If your Unix/Linux distro doesn't have it in package repos

Install using the manual way detailed below.

The manual way

If you want to do it the manual way, the now-recommended method is to install using the get-pip.py script from pip's installation instructions.

Install pip To install pip, securely download get-pip.py Then run the following (which may require administrator access): python get-pip.py If setuptools is not already installed, get-pip.py will install setuptools for you.

I was able to install pip for python 3 on Ubuntu just by running sudo apt-get install python3-pip.

Python 3.4+ and Python 2.7.9+

Good news! Python 3.4 (released March 2014) ships with Pip. This is the best feature of any Python release. It makes the community's wealth of libraries accessible to everyone. Newbies are no longer excluded by the prohibitive difficulty of setup. In shipping with a package manager, Python joins Ruby, Nodejs, Haskell, Perl, Go--almost every other contemporary language with a majority open-source community. Thank you Python.

Of course, that doesn't mean Python packaging is problem solved. The experience remains frustrating. I discuss this at Does Python have a package/module management system?

Alas for everyone using an earlier Python. Manual instructions follow.

Python ≤ 2.7.8 and Python ≤ 3.3

Follow my detailed instructions at https://stackoverflow.com/a/12476379/284795 . Essentially

Official instructions

Per https://pip.pypa.io/en/stable/installing.html

Download get-pip.py, being careful to save it as a .py file rather than .txt. Then, run it from the command prompt.

python get-pip.py

You possibly need an administrator command prompt to do this. Follow http://technet.microsoft.com/en-us/library/cc947813(v=ws.10).aspx

For me, this installed Pip at C:\Python27\Scripts\pip.exe. Find pip.exe on your computer, then add its folder (eg. C:\Python27\Scripts) to your path (Start / Edit environment variables). Now you should be able to run pip from the command line. Try installing a package:

pip install httpie

There you go (hopefully)!

---

if you're using python 3.4+

just type:

python3 -m pip

---

For Ubuntu 12.04 or older,

sudo apt-get install python3-pip

won't work. Instead, use:

sudo apt-get install python3-setuptools ca-certificates
sudo easy_install3 pip

---

Update 2015-01-20:

As per https://pip.pypa.io/en/latest/installing.html the current way is:

wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py

I think that should work for any version

Original Answer:

wget http://python-distribute.org/distribute_setup.py
python distribute_setup.py
easy_install pip

Single Python in system

To install packages in Python always follow these steps:

If the package is for python 2.x: sudo python -m pip install [package] If the package is for python 3.x: sudo python3 -m pip install [package]

Note: This is assuming no alias is set for python

Through this method, there will be no confusion regarding which python version is receiving the package.

Multiple Pythons

Say you have python3 ↔ python3.6 and python3.7 ↔ python3.7

To install for python3.6: sudo python3 -m pip install [package] To instal for python3.7: sudo python3.7 -m pip install [package]

This is essentially the same method as shown previously.

Note 1

How to find which python? Do one of the following:

~ » python3 -c "import sys; print(sys.version)"
3.9.5 (default, Nov 18 2021, 16:00:48)

your python3 command spawns:

~ » python3
Python 3.9.5 (default, Nov 18 2021, 16:00:48) 
[GCC 10.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 

Notice python 3.9.5 in the second line.

Note 2

Change what python3 or python points to: https://askubuntu.com/questions/320996/how-to-make-python-program-command-execute-python-3

---

python3 -m ensurepip

I'm not sure when exactly this was introduced, but it's installed pip3 for me when it didn't already exist.

Older version of Homebrew

If you are on macOS, use homebrew.

brew install python3 # this installs python only
brew postinstall python3 # this command installs pip

Also note that you should check the console if the install finished successfully. Sometimes it doesn't (e.g. an error due to ownership), but people simply overlook the log.

UPDATED - Homebrew version after 1.5

According to the official Homebrew page:

On 1st March 2018 the python formula will be upgraded to Python 3.x and a python@2 formula will be added for installing Python 2.7 (although this will be keg-only so neither python nor python2 will be added to the PATH by default without a manual brew link --force). We will maintain python2, python3 and python@3 aliases.

So to install Python 3, run the following command:

brew install python3

Then, the pip is installed automatically, and you can install any package by pip install <package>.

---

If your Linux distro came with Python already installed, you should be able to install PIP using your system’s package manager. This is preferable since system-installed versions of Python do not play nicely with the get-pip.py script used on Windows and Mac.

Advanced Package Tool (Python 2.x)

sudo apt-get install python-pip

Advanced Package Tool (Python 3.x)

sudo apt-get install python3-pip

pacman Package Manager (Python 2.x)

sudo pacman -S python2-pip

pacman Package Manager (Python 3.x)

sudo pacman -S python-pip

Yum Package Manager (Python 2.x)

sudo yum upgrade python-setuptools
sudo yum install python-pip python-wheel

Yum Package Manager (Python 3.x)

sudo yum install python3 python3-wheel

Dandified Yum (Python 2.x)

sudo dnf upgrade python-setuptools
sudo dnf install python-pip python-wheel

Dandified Yum (Python 3.x)

sudo dnf install python3 python3-wheel

Zypper Package Manager (Python 2.x)

sudo zypper install python-pip python-setuptools python-wheel

Zypper Package Manager (Python 3.x)

sudo zypper install python3-pip python3-setuptools python3-wheel

This is the one-liner I copy-and-paste:

curl https://bootstrap.pypa.io/get-pip.py | python3

Alternate:

curl -L get-pip.io | python3

From Installing with get-pip.py:

To install pip, securely download get-pip.py by following this link: get-pip.py. Alternatively, use curl: curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py Then run the following command in the folder where you have downloaded get-pip.py: python get-pip.py Warning: Be cautious if you are using a Python install that is managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.

If you use several different versions of python try using virtualenv http://www.virtualenv.org/en/latest/virtualenv.html#installation

With the advantage of pip for each local environment.

Then install a local environment in the current directory by:

virtualenv -p /usr/local/bin/python3.3 ENV --verbose

Note that you specify the path to a python binary you have installed on your system.

Then there are now an local pythonenvironment in that folder. ./ENV

Now there should be ./ENV/pip-3.3

use ./ENV/pip-3.3 freeze to list the local installed libraries.

use ./ENV/pip-3.3 install packagename to install at the local environment.

use ./ENV/python3.3 pythonfile.py to run your python script.

Here is my way to solve this problem at ubuntu 12.04:

sudo apt-get install build-essential libncursesw5-dev libssl-dev libgdbm-dev libc6-dev libsqlite3-dev tk-dev

Then install the python3 from source code:

wget https://www.python.org/ftp/python/3.4.0/Python-3.4.0.tar.xz
tar xvf Python-3.4.0.tar.xz
cd Python-3.4.0
./configure
make
make test
sudo make install

When you finished installing all of them, pip3 will get installed automatically.

This is what I did on OS X Mavericks to get this to work.

Firstly, have brew installed

Install python 3.4

brew install python3

Then I get the latest version of distribute:

wget https://pypi.python.org/packages/source/d/distribute/distribute-0.7.3.zip#md5=c6c59594a7b180af57af8a0cc0cf5b4a

unzip distribute-0.7.3.zip
cd distribute-0.7.3
sudo setup.py install
sudo easy_install-3.4 pip
sudo pip3.4 install virtualenv
sudo pip3.4 install virtualenvwrapper

mkvirtualenv py3 

python --version
Python 3.4.1

I hope this helps.

Please follow below steps to install python 3 with pip:

Step 1 : Install Python from download here

Step 2 : you’ll need to download get-pip.py

Step 3 : After download get-pip.py , open your commant prompt and go to directory where your get-pip.py file saved .

Step 4 : Enter command python get-pip.py in cmd.

Step 5 : Pip installed successfully , Verify pip installation by type command in cmd pip --version

What’s New In Python 3.4 ... pip should always be available ... By default, the commands pipX and pipX.Y will be installed on all platforms (where X.Y stands for the version of the Python installation), along with the pip Python package and its dependencies.

https://docs.python.org/3/whatsnew/3.4.html#whatsnew-pep-453

so if you have python 3.4 installed, you can just: sudo pip3 install xxx

---

For python3 try this:

wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python

The good thing is that It will also detect what version of python you have (even if it's an environment of python in your custom location). After this you can proceed normally with (for example)

pip install numpy

source: https://pypi.python.org/pypi/setuptools/1.1.6#upgrading-from-setuptools-0-6

Assuming you are in a highly restricted computer env (such as myself) without root access or ability to install packages...

I had never setup a fresh/standalone/raw/non-root instance of Python+virtualenv before this post. I had do quite a bit of Googling to make this work.

Decide if you are using python (python2) or python3 and set your PATH correctly. (I am strictly a python3 user.) All commands below can substitute python3 for python if you are python2 user. wget https://pypi.python.org/packages/source/v/virtualenv/virtualenv-x.y.z.tar.gz tar -xzvf virtualenv-x.y.z.tar.gz python3 virtualenv-x.y.z/virtualenv.py --python $(which python3) /path/to/new/virtualenv source /path/to/new/virtualenv/bin/activate Assumes you are using a Bourne-compatible shell, e.g., bash Brilliantly, this virtualenv package includes a standalone version of pip and setuptools that are auto-magically installed into each new virtualenv. This solves the chicken and egg problem. You may want to create an alias (or update your ~/.bashrc, etc.) for this final command to activate the python virtualenv during each login. It can be a pain to remember all these paths and commands. Check your version of python now: which python3 should give: /path/to/new/virtualenv/bin/python3 Check pip is also available in the virtualenv via which pip... should give: /path/to/new/virtualenv/bin/pip

Then... pip, pip, pip!

Final tip to newbie Pythoneers: You don't think you need virtualenv when you start, but you will be happy to have it later. Helps with "what if" installation / upgrade scenarios for open source / shared packages.

pip is installed together when you install Python. You can use sudo pip install (module) or python3 -m pip install (module).

---

And for Windows 8.1/10 OS Users just open cmd (command prompt)

write this : C:\Users\%USERNAME%\AppData\Local\Programs\Python\Python36-32\Scripts

then

just write this : pip3 install {name of package}

Hint: the location of folder Python36-32 may get different for new python 3.x versions

=>Easy way to install Python any version on Ubuntu 18.04 or Ubuntu 20.04 follow these steps:-

Step 1: Update Local Repositories:-

sudo apt update

Step 2: Install Supporting Software:-

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget

Step3: Create directory on your home directory To download the newest release of Python Source Code, navigate to the /python-source-files directory and use the wget command:-

mkdir python-source-files

Step 4: Download the Latest Version of Python Source Code:-

wget https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz

"you can change python version by just modifies this:-"3.7.5" with the version you want example:-"3.5.2"

Step 5: Extract Compressed Files:-

tar –xf Python-3.7.5.tgz or tar xvzf Python-3.7.5.tgz

Step 6: Test System and Optimize Python:-

cd python-3.7.5 or your version of python.

Step 7: Now configure(Using the ––optimization option speeds code execution by 10-20%.):-

./configure ––enable–optimizations

OR you can also do this also if you facing ssl error:-

./configure --with-openssl

Step 8: Install a Second Instance of Python:-

sudo make altinstall

"It is recommended that you use the altinstall method. Your Ubuntu system may have software packages dependent on Python 2.x.

OR

If you want to Overwrite Default Python Installation/version:-

sudo make install"

Step 9:Now check Python Version:-

python3 ––version

Step 10: To install pip for python3 just go with this command:-

sudo apt-get install python3-pip

---

If you used the command "python get-pip.py", you should have the 'pip' function for Python3. However, 'pip' for Python2 might still be present. In my case I uninstalled 'pip', which removed it from Python2.

After that I ran "python get-pip.py" again. (Make sure that 'get-pip.py' is saved in the same folder as Python3.) The final step was to add the directory with 'pip' command to $PATH. That solved it for me.
