When I tried to execute http-server from nodejs (with command 'http-server –o'), I had got the error. The solution requires to update execution policy.

The code of error is:

http-server : File C:\Users\Alexey\AppData\Roaming\npm\http-server.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.

+ http-server -o

+ FullyQualifiedErrorId : UnauthorizedAccess

To fix it you should run PowerShell as administrator and execute command

Set-ExecutionPolicy Unrestricted

It will update the execution policy of scripts. Of course, Microsoft thinks that it’s not secured. And it’s true. That’s why I recommend you to return the value of this item back to Restricted after your work.

Update execution policy

Update execution policy

To return the default value use the command:

Set-ExecutionPolicy Restricted
