启动PowerShell会话时出错

Question

我正常使用PowerShell（仅使用posh git），突然发生了一个奇怪的行为，我试图重启会话，当我这样做时，我遇到了很多错误，是：

我尝试重新启动PC，但每次启动新的PowerShell会话时仍然遇到同样的问题，我注意到很多命令都不起作用，导致这个问题的原因是什么？我该怎么做才能解决它？

更新

我删除了PoshGit添加的配置文件，在开始新会话时，我没有任何错误，但是PowerShell仍然无法识别命令，例如调用Clear-host，会抛出很多我无法解决的错误了解原因！

Answer 1

您的PSModulePath系统环境变量缺失C:\windows\system32\WindowsPowerShell\v1.0\Modules，这是PowerShell中所有＆＃34; system＆＃34; /内置模块的位置。

你安装过的东西（可能是他的git？）可能搞砸了。将其添加到系统变量中。

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

Answer 2

如果您刚刚安装了posh-git，它会添加一些Powershell profile files，基本上每次执行PowerShell会话时都会执行一些.ps1文件。

只需删除（或修复）它们;从投掷错误的路径可能它们在C:\Users\aymen.daoudi\Documents\WindowsPowerShell\...

Answer 3

在安装posh-git ... profile.example.ps1 is not recognized as the name of a cmdlet后加载我的个人资料时，我遇到类似的shell错误消息。

当我从旧机器上复制文件到我的用户目录时，发生了这种情况 - 较旧的 poshgit powershell user profiles came along with it。

我的修复方法是从下面的路径重命名旧的posh-git个人资料...

原始档案路径

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

新的个人资料名称

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新的配置文件（大小从5KB增加到1KB ）。
