windows - 启动 PowerShell session 时出错

Question

我正常使用 PowerShell(正在使用 posh git，只是提一下)，突然发生了一个奇怪的行为，我试图重新启动 session ，当我这样做时，我得到了很多错误，它们是:

我尝试重新启动 PC，但每次启动新的 PowerShell session 时仍然出现同样的问题，我注意到很多命令都不起作用，是什么导致了这个问题？我应该怎么做才能解决它？

更新

我删除了 PoshGit 添加的配置文件，当开始一个新的 session 时，我没有任何错误，但是 powershell 仍然无法识别命令，例如调用 Clear-host，抛出很多我无法识别的错误了解原因!

Answer 1

你是 PSModulePath 系统环境变量丢失 C:\windows\system32\WindowsPowerShell\v1.0\Modules 这是所有“系统”/PowerShell 中的内置模块。

你安装的东西(也许是 posh git？)可能把它搞砸了。将其添加到系统变量中。

在没有 PowerShell 的情况下，最简单的方法是使用 GUI，如下所述: http://www.computerhope.com/issues/ch000549.htm
