使用Entity Framework Core 解决win7 6.1版本下powershell 2.0 升级到3.0的问题

 PowerShell 打开后输入 $PSVersionTable.PSVersion  显示版本是2.0

下载地址：https://www.microsoft.com/en-us/download/details.aspx?id=34595

下载 

但是运行报错 此更新不适用本计算机

然后网上说把.msu改成.cab，然后在解压缩 用下面的命令安装

dism.exe /online /Add-Package /PackagePath:C:\Download\Windows6.1-KB2506143-x64.cab 

可是还是报错 87

没办法去国外网站查  DISM. Log  错误日志
