不再識別 PowerShell 命令

我使用 Chocolately 在我的 Win7 x64 電腦上安裝了一個軟體包。作為安裝的一部分，它想要將 PowerShell 升級到 5.0。由於發生這種情況，基本的 PowerShell 命令不再運作。我在網路上搜尋了一下，並沒有真正找到任何有用的東西。我真的很困惑該怎麼辦。

這是一個例子：

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別名，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 中設定了另一個別名，我可以看到它正在被識別。如果我輸入 xx 我的 PowerShell 實例將關閉：

function global:xx
{   
    exit
}

$env:psmodulepath 似乎是對的：

PS>$env:psmodulepath

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

PowerShell 指令不再運作

$env:psmodulepath 似乎是對的：

$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

"你的中間有一個（雙引號），$env:psmodulepath但我的安裝中沒有：

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

您可以透過自己明確設定來刪除雙引號$env:psmodulepath。
