Why powershell does not run Angular commands?
JavascriptAngularPowershellAngular CliJavascript Problem Overview
I have started to learn Angular but I note that powershell in Windows gives me an error whenever I make an angular command like:
ng new new-app
or
ng serve
this is the error what I got:
ng : File C:\Users\< username >\AppData\Roaming\npm\ng.ps1 cannot be loaded because
running scripts is disabled on this system. For more information, see
about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.
At line:1 char:1
+ ng serve
+ ~~
+ CategoryInfo : SecurityError: (:) [], PSSecurityException
+ FullyQualifiedErrorId : UnauthorizedAccess
P.S. I try these commands in cmd and it works.
Javascript Solutions
Solution 1 - Javascript
Remove ng.ps1 from the directory C:\Users\%username%\AppData\Roaming\npm\ then try clearing the npm cache at C:\Users\%username%\AppData\Roaming\npm-cache\
Solution 2 - Javascript
I solved my problem by running below command
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
Solution 3 - Javascript
> script1.ps1 cannot be loaded because running scripts is disabled on > this system. For more information, see about_Execution_Policies at > http://go.microsoft.com/fwlink/?LinkID=135170
This error happens due to a security measure which won't let scripts be executed on your system without you having approved of it. You can do so by opening up a powershell with administrative rights (search for powershell in the main menu and select Run as administrator from the context menu) and entering:
set-executionpolicy remotesigned
Solution 4 - Javascript
Step 1
First, you have to need to open the command prompt and run this command.
set-ExecutionPolicy RemoteSigned -Scope CurrentUser
Step 2
Now you have to run the second command on your system. This command is:
Get-ExecutionPolicy
Step 3
To view their policy, you need to run this command in your command prompt:
Get-ExecutionPolicy -list
Solution 5 - Javascript
open windows powershell, run as administrater and SetExecution policy as Unrestricted then it will work.
