#webdev #npm #challenge #developers

When running npm commands in PowerShell, developers might encounter an error message similar to the following:

== PHOTO (Describe issue by photo) ==

== TEXT (Describe issue by text) ==
npm : File C:\Program Files\nodejs\npm.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 + npm run dev + ~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess

Solution
To resolve this issue, follow these steps:

1. Open PowerShell as Administrator:

Press Win + X and select Windows PowerShell (Admin). This ensures you have the necessary permissions to change the execution policy.

2. Check the Current Execution Policy:

In the PowerShell window, type the following command and press Enter:

powershell
Get-ExecutionPolicy
If the result is Restricted, it means script execution is disabled on your system.

3. Set the Execution Policy to RemoteSigned:

To change the execution policy, type the following command and press Enter:

powershell
Set-ExecutionPolicy RemoteSigned
You might be prompted to confirm the change. Type Y and press Enter to confirm. The RemoteSigned policy allows scripts created on your local computer to run, and scripts downloaded from the internet must be signed by a trusted publisher.

4. Verify the New Execution Policy:

To ensure the new policy is set correctly, type the following command and press Enter:

powershell
Get-ExecutionPolicy
The result should now be RemoteSigned.

5. Run Your npm Command Again:

With the execution policy set to RemoteSigned, you can now run your npm command without encountering the execution policy error:

powershell
npm run dev
