爲什麼我無法讓我的模塊從PSModulePath中的目錄加載？

Question

我試圖安裝一個PS模塊，以便它可以從任何地方導入。我已經將我的安裝目錄添加到環境變量中，並且沒有工作，所以我嘗試將我的模塊放入PSCX目錄，因爲我知道這個目錄有效。以下是顯示問題的命令行歷史記錄。爲什麼「import-module foo」不能在這裏工作？

C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx> $env:PSModulePath 
C:\Users\chris\Documents\WindowsPowerShell\Modules;C:\Program Files (x86)\PowerShell  Community Extensions\Pscx3\;C:\windows\system32\WindowsPowerShell\v1.0\Modules\ 

# There's my module; foo.psm1 
C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx> dir *.psm1 


    Directory: C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx 


Mode   LastWriteTime  Length Name 
----   -------------  ------ ---- 
-a---  3/28/2013 10:37 AM   44 foo.psm1 
-a--- 10/20/2012 8:52 PM  19658 Pscx.psm1 


# this works, as expected, so my PSModulePath seems correct. 
C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx> import-module -force pscx 

# I expect this to work since the module is in a PSModulePath directory... but it doesn't 
C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx> import-module foo 
import-module : The specified module 'foo' was not loaded because no valid module file was found in any module directory.

# Try again with the extension... nope. 
C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx> import-module foo.psm1

C:\Program Files (x86)\PowerShell Community Extensions\pscx3\Pscx> import-module ./foo.psm1 -verbose:$true 
VERBOSE: Importing function 'fooobar'. 

Answer 1

您需要在此級別創建文件夾foo：

C:\Program Files (x86)\PowerShell Community Extensions\pscx3\foo 

，並把你的foo.ps1文件存在。

然後就可以調用

import-module foo
