启动 PowerShell 会话时出错

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，我试图重新启动会话，当我这样做时，我遇到了很多错误，它们是：

我尝试重新启动 PC，但每次启动新的 PowerShell 会话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，当开始一个新的会话时，我没有任何错误，但是 powershell 仍然不能识别命令，例如调用 Clear-host，抛出很多错误，我可以不明白原因！

Answer 1

如果你刚刚安装了 posh-git 它添加了一些 Powershell profile files，基本上是一些 .ps1 文件在每次 powershell 会话启动时执行。

只需删除（或修复）它们；从抛出错误的路径来看，它们可能在 C:\Users\aymen.daoudi\Documents\WindowsPowerShell\...

Answer 2

您 PSModulePath 缺少系统环境变量 C:\windows\system32\WindowsPowerShell\v1.0\Modules，它是 PowerShell 中所有 "system"/内置模块的位置。

您安装的某些东西（也许 git 很漂亮？）可能把它搞砸了。添加到系统变量中。

不使用 PowerShell 的最简单方法是使用 GUI，如下所述： http://www.computerhope.com/issues/ch000549.htm

Answer 3

我在安装 posh-git ... profile.example.ps1 is not recognized as the name of a cmdlet 后加载我的配置文件时收到类似 shell 的错误消息。

当我将文件从旧机器复制到我的用户目录时，这发生在我身上 - 旧机器 poshgit powershell user profiles came along with it。

我的解决方法是从下面的路径重命名旧的 posh-git 配置文件...

原始配置文件路径

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 变为 1KB）。
