PowerShell 命令不再被识别

我使用 Chocolately 在 Win7 x64 计算机上安装了一个软件包。作为安装的一部分，它想要将 PowerShell 升级到 5.0。自从发生这种情况以来，基本的 PowerShell 命令不再起作用。我在网上搜索过，并没有找到任何有用的东西。我真的不知道该怎么办。

以下是一个例子：

PS>Get-Location
Get-Location : The term 'Get-Location' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ Get-Location
+ ~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Get-Location:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

PS>

我可以看到它正在解析我的命令的别名，例如：

PS>dir
dir : The term 'Get-ChildItem' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ dir
+ ~~~
    + CategoryInfo          : ObjectNotFound: (Get-ChildItem:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

PS>

我在 $profile 中设置了另一个别名，我可以看到它正在被识别。如果我输入 xx，我的 PowerShell 实例将关闭：

function global:xx
{   
    exit
}

$env：psmodulepath 似乎是正确的：

PS>$env:psmodulepath

indows\system32\WindowsPowerShell\v1.0\Modules";C:\Program Files\WindowsPowerShell\Modules

PowerShell 命令不再起作用

$env：psmodulepath 似乎是正确的：

$env:psmodulepath
C:\Users\myuserid\Documents\WindowsPowerShell\Modules;C:\Program Files (x86)\PowerShell Community Extensions\Pscx3\;C:\windows\system32\WindowsPowerShell\v1.0\Modules";C:\Program Files\WindowsPowerShell\Modules

"您的中间有一个（双引号），$env:psmodulepath但在我的安装中却没有：

PS F:\test> $env:psmodulepath
C:\Users\DavidPostill\Documents\WindowsPowerShell\Modules;C:\Program Files\WindowsPowerShell\Modules;C:\Windows\system32\WindowsPowerShell\v1.0\Modules

您可以通过自行明确设置来删除双引号$env:psmodulepath。
