npm can't find package.json

I think, npm init will create your missing package.json file. It works for me for the same case.

Update 2021

npm init

Please refer to Deepali's answer for details.

Original Outdated Answer

I think you forgot to setup the directory for express:

express <yourdirectory>

Once you do that you should be able to see a bunch of files, you should then run the command:

npm install -d

Regards.

I'll be brief but deadly. :) install -d will not work for you. It's simple. Try

$ npm install -g express

Follwing the below steps you well get package.json file.

npm --version
npm install express
npm init -y

If Googling "no such file or directory package.json" sent you here, then you might be using a very old version of Node.js

The following page has good instructions of how to easily install the latest stable on many Operating systems and distros:

https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager

Use the command in win7/win8/win10 (CD) for moving folders:

Enter your projects folder Run: npm install -d

Beginners usually try the npm command from random locations. After downloading or creating a project, you have to cd into this project folder. Inside is the file package.json.

cd <path_to_project>
npm install

try re-install Node.js

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -

sudo apt-get install -y nodejs

sudo apt-get install -y build-essential

and update npm

curl -L https://npmjs.com/install.sh | sudo sh

Node comes with npm installed so you should have a version of npm. However, npm gets updated more frequently than Node does, so you'll want to make sure it's the latest version.

sudo npm install npm -g

Test:

npm -v //The version should be higher than 2.1.8

After this you should be able to run:

npm install

It may be very evident,
but try to launch CMD (for Windows) from the project folder, where your package.json file is located.

Do not launch CMD from System or from "Search bar" in Win or
move to your project folder with help of cd command and then launch npm start.

I had a similar problem with npm. The problem was that I had the project inside two folders of the same name. I resolved it by renaming one of the folders to something else (outer folder recommended).

It by itself says that package.json is not available in your project. So, to create package.json, use the following steps:

open command prompt on your project directory npm init (it will ask you to enter lots of entries like name, version, desc, etc., enter some random values and click enter). type yes and click enter

Now try again.

Go inside the project folder and check whether the package.json file does exist.

If you are creating the project using Visual Studio Angular project, make sure you run this command inside the ClientApp Folder. there is a good chance, you could be looking for project.json file outside the ClientApp folder.

npm init -y 

use this command, it will automatically create package.json file with all your machine information.

I found myself here trying to resolve the same error message:

npm ERR! message ENOENT, no such file or directory 'c:\<some_folder>\package.json'

The error could be due to two reasons:

You do not have the package.json You have the package.json, but you are running npm start in the wrong folder

To troubleshoot the first cause, you need to create a package.json using:

npm init

To fix the second cause, make sure the folder you are running the npm start command is the same folder as the package.json

My issue was I didn't have a package.json file for some reason. After I wget this file into my directory, I was able to run npm install

https://raw.githubusercontent.com/twbs/bootstrap/master/package.json

Thank you! I also tried many options for this. I am also using windows.This command helped and saved my time:

npm install -g npm@lts

ok, try to go to the home "user@user:~$ " (cd + enter key), and npm install -g your your_module.

just install any package you want with -g

npm install -g express

if the package.json file in the project directory is missing then you can create it by npm init.

if the package.json file is already created in the project directory then there is a possibility that you are not running your project from the right path. Use cd your-project-path in the terminal and then run your project from there.

I was experiencing this identical error and terminal (foolishly, on my part) was in a parent directory instead of the correct one (where package.json was correctly located).

All I did in terminal was cd [insert correct directory name here, overwriting brackets] and that corrected the problem.

For the following command

sudo npm install react browserify watchify babelify --save-dev

I got same error

saveError ENOENT: no such file or directory, open '/Users/Path/package.json'

But when I run the command

sudo npm install -gd react browserify watchify babelify --save-dev

then no missing file or directory message appeared.

I have run npm install -y to skip the question step for creating the missing file package.json, y means yes

I was also facing same issue while installing typescript. I just initialized an package.josn file by the following command

npm init -y

And then i installed my typescript

npm install -g -typescript

Please check the directory or the folder in which you're installing your new package. This happened to me as well, My whole project was in a subdirectory and I was trying to install in the main directory. After checking the whole thing I found out that I had to install in the subdirectory where my project files and package.json files are located and it's done. Hope this helps...

the previous tips do not pay attention to any change for me. at the end this works for me:

delete the local repo folder git clone https ... myRebo.git npm install npm start

hope it helps somebody

Adding -g before the package name worked for me. Looking for documentation to explain why this works..

Generate package.json without having it ask any questions. I ran the below comment in Mac and Windows under the directory that I would like to create package.json and it works

$ npm init -y
