It's possible that you changed the execution policy for 64-bit powershell and the package manager is running 32-bit (or vice versa).
I'd try opening 32-bit console (PowerShell (x86)) and setting the execution policy there, as the error is definitely pointing to that kind of resolution.
Make sure you restart visual studio after changing execution policy so that changes can take effect. Also make sure you changed execution policy globally with administrator username and password.
We have been facing the same issue today with Visual Studio 2017 and Entity Framework 6, and none of the solutions proposed here has worked. As a workaround, this is the temporary solution we found to be able to use Entity Framework commands in the Package Manager Console:
Execute the following commands in the Package Manager Console
Set-ExecutionPolicy -Scope Process Bypass
Import-Module "your-solution-directory/packages/EntityFramework<your EF version>/EntityFramework.psd1"
Actually, the Import-Module
command is what the init1.ps1
script does.
