Can't install nuget package because of “Failed to initialize the PowerShell host”

Question

由于“无法初始化PowerShell主机”而无法安装nuget软件包。这是错误加载扩展类型数据文件时发生以下错误：，C：\\ PROGRAM FILES（X86）\\ MICROSOFT VISUAL STUDIO 14.0 \\ COMMON7 \\ IDE \\ EXTENSIONS \\ 2ZQ00DAJ.XOI \\ Modules \\ NuGet \\ NuGet.Types.ps1xml：由于以下验证异常而跳过了文件：文件C：\\ PROGRAM FILES（X86）\\ MICROSOFT VISUAL STUDIO 14.0 \\ COMMON7 \\ IDE \\ EXTENSIONS \\ 2ZQ00DAJ无法加载.XOI \\ Modules \\ NuGet \\ NuGet.Types.ps1xml，因为其操作被软件限制策略（例如使用组策略创建的策略）阻止。

Answer 1

Since you're using VS 2015 x86, you should start a 32bit version of PowerShell/PowerShell ISE as Administrator (won't work if you just' start it without elevated rights, will give you an error) and change ExecutionPolicy to RemoteSigned, like this

Set-ExecutionPolicy RemoteSigned

and after, restart your Visual Studio. Personally, I don't have it here to test, but think this will fix the error you're getting.
