程序包管理器控制台上的PowerShell版本

Question

Hello guys I am new at this so please bear with me, I have just installed Visual Studio 2015 on my windows 10 pro machine.

Am having problems with the version of PowerShell. It wants me to use version 3.0 or above but I cant seem to upgrade the Package Manager Console to the latest version.

I do have PowerShell Version 5 installed but somehow the Package Manager Console is refusing to use it. I have done a full uninstall and re-install be hasn't sort the problem. Can you help please

I Am currently working on this tutorial

when i run this code

[Scaffold-DbContext " 'Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True; '" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models]

It errors, saying Powershell 3.0 or above is required:

[The Entity Framework Core Package Manager Console Tools don't support PowerShell version 2.0. Upgrade to PowerShell version 3.0 or higher, restart Visual Studio, and try again.]

I run $PSVersionTable it returns

由于你升级了powershell，只需重新启动你的windows机器，以便可以应用注册表更新，然后检查它是否不起作用或者你已经做过，然后我怀疑它需要一个旧版本的powershell，已知可以正常使用该版本的visual studio ，那么你可以使用更新版本的VS说2017。
