为什么我不能让我的模块从PSModulePath中的目录加载？

Question

我正在尝试安装一个PS模块，以便可以从任何地方导入它。我已经将我的安装目录添加到环境变量中，但这不起作用，所以我尝试将我的模块放在PSCX目录中，因为我知道它可以工作。下面是演示该问题的命令行历史记录。为什么"import-module foo“在这里不起作用？

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

VERBOSE: Importing function 'fooobar'.

Answer 1

您需要在此级别创建文件夹foo：

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

并将您的foo.ps1文件放在那里。

然后你就可以调用

import-module foo
