exception - 'Nuget.EnvironmentUtility' 的类型初始值设定项引发异常

Question

我在我的第二台电脑上遇到同样的问题。我认为它必须是我在 Visual Studio 中使用的工具的组合，但我经常收到此错误。

Install-Package : The type initializer for 'NuGet.EnvironmentUtility' threw an exception.
At line:1 char:35
+ get-project -all | Install-Package <<<<  xamarin.forms
    + CategoryInfo          : NotSpecified: (:) [Install-Package], TypeInitializationException
    + FullyQualifiedErrorId : System.TypeInitializationException,NuGet.PowerShell.Commands.InstallPackageCommand

我最终搞砸了卸载/重新安装 nuget，重新启动我的机器，并删除配置文件，直到它再次工作。我永远不知道究竟是哪个部分真正修复了它。

有没有其他人看到这个？正确的解决步骤是什么？
