启动PowerShell会话时出错

Question

我通常使用PowerShell (刚才提到的是使用posh git )，突然发生了一个奇怪的行为，我试图重新启动会话，当我重新启动时，我得到了许多错误，这些错误是：

我试着重新启动PC，但每次启动新的PowerShell会话时仍然存在相同的问题，我注意到许多命令不工作，是什么原因造成了这个问题？我该怎么做才能解决这个问题？

更新

我删除了PoshGit添加的配置文件，在启动新会话时，我没有任何错误，但是powershell仍然不识别命令，例如调用清除主机，抛出了许多我无法理解原因的错误！

Answer 1

您是PSModulePath系统环境，但是缺少了C:\windows\system32\WindowsPowerShell\v1.0\Modules，它是PowerShell中所有“system”/内置模块的位置。

你安装的东西(也许是时髦的？)可能搞砸了。将其添加到系统变量中。

在不使用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

Answer 2

如果您刚刚安装了posh，它添加了一些Powershell配置文件，基本上在每次启动powershell会话时都会执行一些.ps1文件。

只需删除(或修复)它们；从抛出的错误的路径中删除(或修复)--可能它们在C:\Users\aymen.daoudi\Documents\WindowsPowerShell\...中

Answer 3

在安装posh-git . profile.example.ps1 is not recognized as the name of a cmdlet之后加载配置文件时，我收到了类似的shell错误消息。

当我从一台旧机器--旧的poshgit powershell用户配置文件也伴随而来。 --复制文件到我的用户目录时，我就遇到了这种情况。

我的解决办法是从下面的路径重命名旧的posh-git配置文件..。

原始轮廓路径

C:\Users\<username>\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1

新配置文件名称

C:\Users\<username>\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1.notused

在choco uninstall poshgit和choco install poshgit之后，使用正确的数据创建了一个新的配置文件(大小从5KB到1KB )。
