When I faced this problem, by that time I have already tried triggering this command from Pwershell, both admin and non admin
Got this error:
ng : File C:UsersvishiAppDataRoamingnpmng.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 –open
- CategoryInfo : SecurityError: (:) , PSSecurityException
- FullyQualifiedErrorId : UnauthorizedAccess
Then I tried running from CMD as this issue was because of security policies applied on Powershell, then CMD showed this error:
”’The new command requires to be run outside of a project, but a project definition was found at C:UsersvishiImprovAppangular.json".
After executing following command:
Security policy got updated, and then I triggered "ng serve –open" from VS terminal and then it worked.
