I am trying to use pip behind a proxy at work.
One of the answers from this post suggested using CNTLM. I installed and configured it per this other post, but running cntlm.exe -c cntlm.ini -I -M http://google.com
gave the error Connection to proxy failed, bailing out
.
I also tried pip install -–proxy=user:pass@localhost:3128
(the default CNTLM port) but that raised Cannot fetch index base URL http://pypi.python.org/simple/
. Clearly something's up with the proxy.
Does anyone know how to check more definitively whether CNTLM is set up right, or if there's another way around this altogether? I know you can also set the http_proxy
environment variable as described here but I'm not sure what credentials to put in. The ones from cntlm.ini
?
With Ubuntu I could not get the proxy option to work as advertised – so following command did not work:
sudo pip --proxy http://web-proxy.mydomain.com install somepackage
But exporting the https_proxy
environment variable (note its https_proxy
not http_proxy
) did the trick:
export https_proxy=http://web-proxy.mydomain.com
then
sudo -E pip install somepackage
Under Windows dont forget to set
SET HTTPS_PROXY=<proxyHost>:<proxyPort>
what I needed to set for
pip install pep8
SET HTTPS_PROXY=username:password@<proxyHost>:<proxyPort>
and it was not working.
SET HTTPS_PROXY = https://512893:Pass%23h98@proxy.example.com:6050
for username 512893
& password pass#h98
. Remember to url encode special characters in password or username (#
in this case). Maybe also try setting the HTTP_PROXY
flag as well.
To setup CNTLM for windows, follow this article. For Ubuntu, read my blog post.
Edit:
Basically, to use CNTLM in any platform, you need to setup your username and hashed password, before using http://127.0.0.1:3128
as a proxy to your parent proxy.
Edit the config and add important information like domain, username, password and parent proxy. Generate hashed password. Windows cntlm –c cntlm.ini –H Ubuntu/Linux cntlm -v -H -c /etc/cntlm.conf Remove plain text password from the config and replace them with the generated passwords.
To check if working:
Windows cntlm –M http://www.google.com
Ubuntu/Linux sudo cntlm -M http://www.google.com/
For more detailed instructions, see links above.
Update:
Just for completeness sake, I was able to configure and use CNTLM in Windows recently. I encountered a problem during the syncing process of Kindle for PC because of our proxy and installing and configuring CNTLM for Windows fixed that issue for me. Refer to my article for more details.
--trusted-host pypi.python.org
which did the trick for me.
It was not working for me. I had to use https at work:
pip install --proxy=https://user@mydomain:port somepackage
In order to update, add -U.
pip install somepackage --proxy https://user:password@mydomain:port
user
to put, maybe that's because there is none to put: pip install --proxy=https://mydomain:port somepackage
You can continue to use pip over HTTPS by adding your corporation's root certificate to the cacert.pem file in your site-packages/pip folder. Then configure pip to use your proxy by adding the following lines to ~/pip/pip.conf (or ~\pip\pip.ini if you're on Windows):
[global]
proxy = [user:passwd@]proxy.server:port
That's it. No need to use third party packages or give up HTTPS (of course, your network admin can still see what you're doing).
~/.pip/pip.conf
then export PIP_CONFIG_FILE=/root/.pip/pip.conf
and my installation worked! Thanks!
[Python37]\Lib\site-packages\pip\_vendor\certifi\cacert.pem
. Export your corp's SSL interception certificate in Base64 .cer format, paste the public key into that file, and voilà, full https support behind the corporate proxy.
AppData/Roaming/pip/pip.ini
....
for windows; set your proxy in command prompt as
set HTTP_PROXY=domain\username:password@myproxy:myproxyport
example: set http_proxy=IND\namit.kewat:xl123456@192.168.180.150:8880
This worked for me (on Windows via CMD):
pip install --proxy proxyserver:port requests
$ pip --proxy http://proxy-host:proxy-port install packagename
This is what worked for me on
pip --proxy http://username:password@proxy-host:proxy-port install <package>
Under our security policy I may not use https with pypi, SSL-inspection rewrites certificates, it breaks the built-in security of pip for www.python.org. The man in the middle is the network-admin.
So I need to use plain http. To do so I need to override the system proxy as well as the default pypi:
bin/pip install --proxy=squidproxy:3128 -i http://www.python.org/pypi --upgrade "SQLAlchemy>=0.7.10"
Security
has four syllables. Too many for Trump.
Phone as mobile hotspot/USB tethering
If I have much trouble finding a way through the corporate proxy, I connect to the web through my phone (wireless hotspot if I have wifi, USB tether if not) and do a quick pip install
.
Might not work for all setups, but should get most people by in a pinch.
Open the Windows command prompt.
Set proxy environment variables.
set http_proxy=http://user:password@proxy_ip:port
set https_proxy=https://user:password@proxy_ip:port
Install Python packages using proxy in the same Windows command prompt.
pip install --proxy="user:password@proxy_ip:port" package_name
In Windows 7:
pip install --proxy DOMAIN\user:password@proxyaddress:port package
i.e.:
pip install --proxy BR\neo:p4ssw0rd@myproxyrocks.com.br:8080 virtualenv
In Ubuntu 14.04 LTS
sudo pip --proxy http://PROXYDOM:PROXYPORT install package
Cheers
I had the same issue : behind a corporate proxy with auth at work, I couldn't have pip work, as well as Sublime Text 2 (well, it worked with custom setup of my proxy settings). For pip (and I'll try that on git), I solved it installing cntlm proxy. It was very simple to configure :
Edit cntlm.ini Edit "Username", "Domain", "Password" fields Add a "Proxy" line, with your proxy settings : server:port Make sure the line "NoProxy" integrates "localhost" (like that by default) Note the default port : 3128 Save and that's it.
To test that works, just launch a new command line tool, and try :
pip install django --proxy=localhost:3128
That worked for me. Hope this will help you.
Set up invironment variable in Advanced System Settings. In Command prompt it should behave like this :
C:\Windows\system32>echo %http_proxy% http://username:passowrd@proxy:port C:\Windows\system32>echo %https_proxy% http://username:password@proxy:port
Later , Simply pip install whatEver
should work.
I could achieve this by running:
pip install --proxy=http://user:pass@your.proxy.com:3128 package==version
I'm using Python 3.7.3 inside a corporative proxy.
if you want to upgrade pip by proxy, can use (for example in Windows):
python -m pip --proxy http://proxy_user:proxy_password@proxy_hostname:proxy_port insta
ll --upgrade pip
For windows users: if you want to install Flask-MongoAlchemy then use the following code
pip install Flask-MongoAlchemy --proxy="http://example.com:port"**
Using pip behind a work proxy with authentification, note that quotation is required for some OSes when specifing the proxy url with user and password:
pip install <module> --proxy 'http://<proxy_user>:<proxy_password>@<proxy_ip>:<proxy_port>'
Documentation: https://pip.pypa.io/en/stable/user_guide/#using-a-proxy-server
Example:
pip3 install -r requirements.txt --proxy 'http://user:password@192.168.0.1:1234'
Example:
pip install flask --proxy 'http://user:password@192.168.0.1:1234'
Proxy can also be configured manually in pip.ini. Example:
[global]
proxy = http://user:password@192.168.0.1:1234
Documentation: https://pip.pypa.io/en/stable/user_guide/#config-file
export http_proxy
). Consider solving the problem and updating your answer so that it provides a solution.
If you are connecting to the internet behind a proxy, there might be problem in running the some commands.
Set the environment variables for proxy configuration in the command prompt as follows:
set http_proxy=http://username:password@proxyserver:proxyport
set https_proxy=https://username:password@proxyserver:proxyport
At CentOS (actually I think all linux distros are similar) run
env|grep http_proxy
and
env|grep https_proxy
check what is the output of those commands (they should contain your proxy addresses).
If the outputs are empty or have incorrect values, modify them, for ex:
export http_proxy=http://10.1.1.1:8080
export https_proxy=http://10.1.1.1:8080
Now try to fetch and install some packages by using pip:
pip --proxy http://10.1.1.1:8080 install robotframework
and actually I have never met the case when it didn't work. For some systems you need to be a root (sudo is not enough).
Warning, there is something very bad with the "pip search" command. The search command do not use the proxy setting regardless of the way it's being passed.
I was trying to figure out the problem only trying the "search" command, and found this post with detailed explanation about that bug: https://github.com/pypa/pip/issues/1104
I can confirm the bug remains with pip 1.5.6 on Debian 8 with python 2.7.9. The "pip install" command works like a charm.
I got the error:
chris@green:~$ sudo http_proxy=http://localhost:3128 pip install django==1.8.8

No distributions at all found for django==1.8.8
Storing complete log in /home/chris/.pip/pip.log
(The proxy server's port is ssh port forwarded to localhost:3128
).
I had to set both http and https proxies to make it work:

I am also no expert in this but I made it work by setting the all_proxy
variable in the ~/.bashrc file. To open ~/.bashrc
file and edit it from a terminal run following commands,
gedit ~/.bashrc &
Add following at the end of file,
export all_proxy="http://x.y.z.w:port"
Then either open a new terminal or run following in the same terminal,
source ~/.bashrc
Just setting http_proxy
and https_proxy
variables aren't enough for simple usage pip install somepackage
. Though somehow sudo -E pip install somepackage
works, but this have given me some problem in case I am using a local installation of Anaconda in my users' folder.
P.S. - I am using Ubuntu 16.04.
How about just doing it locally? Most likely you are able to download from https source through your browser
Download your module file (mysql-connector-python-2.0.3.zip /gz... etc). Extract it and go the extracted dir where setup.py is located and call: C:\mysql-connector-python-2.0.3>python.exe setup.py install
This is what works for me:
pip --proxy proxy url:port command package
Set the following environment variable: export PIP_PROXY=http://web-proxy.mydomain.com
If you are using Linux, as root:
env https_proxy=http://$web_proxy_ip:$web_proxy_port pip install something
When you use env it exports the variable https_proxy for the current execution of the command pip install.
$web_proxy_ip is the hostname or IP of your Proxy $web_proxy_port is the Port
2022 for windows:
I know there are many answers and nearly every other question with pip
and behind a proxy
is refering to this question:
So in my opinion it is on the one hand the proxy thing, which is answered in the questions below.
pip install --proxy=https://<windowsuser>:<pw>@<proxy>:port package
After that you have to deal with the SSL certificates. You have to add the trusted sources. Usually they are standing in the Error message
. For example: ERROR: .... host='files.pythonhosted.org'
And here is my solution for installing for example Django
:
pip install Django --proxy http://windowsuser:password@proxy:port --trusted-host pypi.python.org --trusted-host pypi.org --trusted-host files.pythonhosted.org
I solved the problem with PIP in Windows using "Fiddler" (https://www.telerik.com/download/fiddler). After downloading and installing, do the following:
"Rules" => click "Automatically Authenticate"
Example: pip install virtualenv -proxy 127.0.0.1:8888
Just open your prompt and use.
