Cannot find module #angular\cli\bin\ng - node.js

Question

I'm getting into trouble with anngular-cli installation because it doesn't recognize the ng command in my git bash but it works in my cmd on Windows 7.
I looked for some issues on the web but I didn't really find a solution.
Here, the error :
ng -v
module.js:549
throw err;
^
Error: Cannot find module 'C:\Program
Files\Git\node_modules\#angular\cli\bin\ng'
at Function.Module._resolveFilename (module.js:547:15)
at Function.Module._load (module.js:474:25)
at Function.Module.runMain (module.js:693:10)
at startup (bootstrap_node.js:191:16)
at bootstrap_node.js:612:3
This error happened the first time I used ng after installing Node and angular-cli globally.
I didn't get this error when I was working on my laptop on Windows 10.

Answer 1

Problem:
Error: Cannot find module
'..\AppData\Roaming\npm\node_modules\angular-cli\bin\ng' angularJs
Solution:
uninstall angular cli if you have already installed it
npm uninstall -g #angular/cli
Delete the C:\Users\Satish\AppData\Roaming\npm\node_modules#angular folder if it still exists after the uninstall
reinstall angular-cli globally
npm install -g #angular/cli

Answer 2

First, uninstall the angular cli using
npm uninstall -g #angular/cli
Then delete the "NPM" and "Npm-cache" folder under "Roaming" folder.
Now again install the Angular cli using
npm install -g #angular/cli

Answer 3

It worked for me only by removing npm and npm-cache folders from AppData then running :
npm uninstall -g #angular/cli
Then running :
npm install -g #angular/cli

Answer 4

In my case, i fixed it simply just by renaming my project folder.
before : "d/Gdrive/Sem 6 & 7/[project name]"
after : "d/Gdrive/Sem 67/[project name]"
So i guess u may not put special characters in your folder name.

Answer 5

Looks like a dependency was removed somewhere. I worked around this by:
For local angular-cli: npm install #angular-devkit/core --save-dev
For global angular-cli: npm install -g #angular-devkit/core
Edit: As discussed below, you should perhaps not use --save-dev here.

Answer 6

Remove existing angular
npm uninstall -g #angular/cli
and Install
npm install -g #angular/cli --force

Answer 7

reinstall node_modules
git clean -dfx
npm i
if persist, use yarn install first, then repeat above

Answer 8

The git bash is installed in C:\Program Files\Git where you never find the node_module folder that's why this error occurred
When you hit ng command from CMD it will look node_module folder in C:\Users\uername\AppData\Roaming\npm\ - where npm install global dependency and eventually it finds node_modules folder.
Basically for windows try to run from cmd.

Answer 9

In my case the problem is
npm ERR! code EEXIST
npm ERR! path C:\Program Files\nodejs\node_modules\#angular\cli\bin\ng.js
npm ERR! dest C:\Program Files\nodejs\ng
npm ERR! EEXIST: file already exists, cmd shim 'C:\Program Files\nodejs\node_modules\#angular\cli\bin\ng.js' -> 'C:\Program Files\nodejs\ng'
npm ERR! File exists: C:\Program Files\nodejs\ng
npm ERR! Remove the existing file and try again, or run npm
npm ERR! with --force to overwrite files recklessly.
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\<UserId>\AppData\Roaming\npm-cache\_logs\2022-01-03T20_13_43_709Z-debug.log
Solution:
I use this comment of npm 5 line on the shell
$ npm ERR! File exists: C:\Program Files\nodejs\ng
Delete the file ng and run:
npm install -g #angular/cli
And Done!

Answer 10

I faced the same problem but running npm install solved my problem.

Answer 11

I had this error in Angular Console starting with release 11.
I was missing a locale cli. So
npm install #angular/cli
solved my problem

Answer 12

It might be an issue with the package installation. Sometimes the installation might brake due to network issues. Also the access permission affects the installation.
So, try to install the package by running command prompt (CMD) as Run as administrator.
Follow the steps to resolve the issue.
1.Run CMD as Run as administrator mode.
2.Uninstall angular cli.
npm uninstall -g #angular/cli
3.Remove npm package files from the appdata folder.
Open Run option by pressing Windows + R key. Then type %appdata% and press OK.
Open the npm folder from the Roaming folder that you got in the explorer.
Delete ng and ng.cmd files from the npm folder if exists.
Open node_modules folder from there and delete #angular and angular/cli folder if exists.
4.Reinstall the angular cli
npm install -g #angular/cli

Answer 13

npm install --legacy-peer-deps
npm cache clean --force

Answer 14

If the environment variable path is properly set , please run ng in an angular project otherwise it will keep showing that error

Answer 15

once you run npm uninstall -g #angular/cli, check if there is an error in the console, it is usually a message with red line says "err!", mine said that it was unable to delete a file , follow the path of the file and delete manually ,then run npm uninstall -g #angular/cli and npm uninstall #angular/cli, when it goes successfully , run npm install -g #angular/cli , that should fix it.

Answer 16

If most suggested and obvious solution below do not work
npm uninstall -g #angular/cli
remove roaming -> npm
npm install -g #angular/cli
Try to upgrade Node.js version. This solved the problem in my case after severl hours of investigation

Answer 17

Try deleting the node_modules folder (not the AppData one), the one in your project folder, and try reinstalling angular again.

Answer 18

If you have MAC(Mackbook) pc use brew command because we can not install angular-cli from npm command
