ng : The term 'ng' is not recognized as the name of a cmdlet, function Visual Studio Code Terminal

Question

In Visual Studio Code, when I am running command ng build, I am getting this error:

PS D:\Dashboard\Test1> ng build
ng : The term 'ng' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if
a path was included, verify that the path is correct and try again.
At line:1 char:1
+ ng build
+ ~~
    + CategoryInfo          : ObjectNotFound: (ng:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

I have added these environment variables in Path:

%USERPROFILE%\AppData\Local\Microsoft\WindowsApps;
C:\Users\Avind\AppData\Local\Programs\Microsoft VS Code\bin;
C:\Users\Avind\AppData\Roaming\npm;

How can I get rid of this issue?

Note: I have node.js in C:\Program Files\nodejs. From the command prompt, ng new project is not working, but it is working from a node.js command.

After executing npm install -g @angular/cli@latest from the Visual Studio Code terminal, I am getting the below message and the ng command is not working:

PS D:\Path\Test1> npm install -g @angular/cli@latest

Answer 1

You need to install the latest Angular CLI to make the 'ng' command work. You can run it from the command terminal or Visual Studio Code terminal:

npm install -g @angular/cli@latest

If it is still not working, uninstall and reinstall Node.js from Programs and Features.

Answer 2

As here Angular CLI, make sure you installed Angular CLI.
You can run this command from anywhere on your system.

npm install -g @angular/cli
ng --version

It should print something like this:

     _                      _                 ____ _     ___
    / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
   / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |
  / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |
 /_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
                |___/


Angular CLI: 13.1.2
Node: 16.13.1
Package Manager: npm 8.1.2
OS: win32 x64

Angular:

Answer 3

This worked for me. Trying previous answers did not work in my case.

Run this command

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Reference:

ng : File \AppData\Roaming\npm\ng.ps1 cannot be loaded. The file npm\ng.ps1 is not digitally signed Angular Error when running commands

Answer 4

I received a similar error while working with PowerShell, and I used the following command to resolve it:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Answer 5

Try this command:

npm install -g @angular/cli@latest

Then use the following:

1. Open Windows PowerShell

2. Run

   Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
   Get-ExecutionPolicy
   

   and you get

   RemoteSigned
   

3. Run

   Get-ExecutionPolicy -list
   

   You get

   Scope          ExecutionPolicy
   -----          ---------------
   MachinePolicy  Undefined
   UserPolicy     Undefined
   Process        Undefined
   CurrentUser    RemoteSigned
   LocalMachine   Undefined
   

Answer 6

Method 1:

Step 1: Run the command "Set-ExecutionPolicy RemoteSigned -Scope CurrentUser"

When you run this command, you can see that your system has set all policies for the current user as remotely. It will take few seconds to complete this process.

Step 2: Enter image description here

Get-ExecutionPolicy -list

When you run this command, a few policies are shown on your monitor screen.

Verify if the policy for the current user is RemoteSigned. If yes, this it should work now. If no, please try method 2 as below:

Method 2:

Find the file "ng.ps1" in path C:\Users%username%\AppData\Roaming\npm\ and remove it from the directory.

If you don't know the file extension, then right-click on the file -> go to Properties and check the extension of file.

Note: Please do not remove any other file. Make sure you are removing the ng.ps1 file only.

Answer 7

I had the same issue. I reopened CMD in a new tab and typed the same thing like this:

ng g c componentname

and hit Enter, it worked for me.

Answer 8

This issue may be due to the Path environment variable not being set.

This worked for me:

Run:

npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm install -g @angular/cli

After installing, you enter Advanced System Configuration → Environment Variables → Path → Edit.

If this Angular variable is not in the path, you add: "C:\Users\youruser\AppData\Roaming\npm"

Close the terminal, open it and run the command again.

Answer 9

I solved this problem by just running these three commands:

npm uninstall -g @angular/cli angular-cli
npm cache clean or npm cache clean --force
npm install -g @angular/cli@latest

It worked.
