Why PowerShell Does Not Run Angular Commands?
So, you've just started learning Angular and you're excited to build your first app. But when you try to run Angular commands in PowerShell, you hit a roadblock. Don't worry, you're not alone! Many beginners face the same issue when trying to run Angular commands in PowerShell on Windows.
The Error Message
To give you a better understanding, let's take a look at the error message you encountered:
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
The Cause
The error occurs because of the execution policy set in PowerShell. PowerShell has a security feature called "execution policies" that control the running of scripts. By default, the execution policy is set to "Restricted" which prevents the execution of scripts, including the ng
script used by Angular.
The Solution
To overcome this issue and enable the execution of scripts, you need to change the execution policy. Here are the steps to do it:
Step 1: Open PowerShell as an Administrator
Right-click on the PowerShell icon, then select "Run as Administrator."
Step 2: Check the Current Execution Policy
In the elevated PowerShell window, type the following command and press Enter:
Get-ExecutionPolicy
This will show you the current execution policy set on your system.
Step 3: Change the Execution Policy
To enable script execution, type the following command and press Enter:
Set-ExecutionPolicy RemoteSigned
You may be prompted to confirm the change. Type "Y" for Yes and press Enter.
Step 4: Run Angular Commands
Now, you should be able to run Angular commands in PowerShell without any issues. Try running ng new new-app
or ng serve
again and see if it works.
An Alternative Solution
If you prefer not to change the execution policy, you can also run Angular commands in Command Prompt (CMD) instead. As you mentioned in your context, the commands work fine in CMD.
