自定义功能无法识别

标签: function powershell module

在我当前的会话期间,我点到我的PowerShell配置文件中的功能不可用。该函数如下所示:

# \MyModules\Foobar.ps1

function Foo-Bar {
    Write-Host "Foobar";
}

# Test loading of this file
Foo-Bar;

我的个人资料如下:

# \Microsoft.PowerShell_profile.ps1

Write-Host "Loading MyModules..."
Push-Location ~\Documents\WindowsPowerShell\MyModules

.\Foobar.ps1

Pop-Location
Write-Host "Done"

当我运行. $profile时,输出如下所示,这确认了Foo-Bar函数的工作原理。

> . $profile 

Loading MyModules...
Foobar
Done

之后运行Foo-Bar函数会爆炸,如下所示:

Foo-Bar : The term 'Foo-Bar' 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
+ Foo-Bar
+ ~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Foo-Bar:String) [],        
                              CommandNotFoundException

    + FullyQualifiedErrorId : CommandNotFoundException

为什么不可用?

嗯,有几种方法可以解决它。请注意,这些方法中的任何一种都不需要您在导入模块之前对其进行点调用。

1)使用适当的模块MyMethod.psm1

# MyMethod.psm1 (m for module)
function MyMethod {
    # my method
}
Export-ModuleMember MyMethod

# then in your profile
Import-Module "MyMethod"

2)如果你有一组方法,需要将它们分成多个文件

# MyMethod1.ps1
function Invoke-MyMethod1{
    # my method1
}
Set-Alias imm Invoke-MyMethod1
# MyMethod2.ps1
function Something-MyMethod2 {
    # my method2
}
Set-Alias smm Something-MyMethod2
# MyMethod.psm1 (m for module)
Push-Location $psScriptRoot
. .\MyMethod1.ps1
. .\MyMethod2.ps1
Pop-Location

Export-ModuleMember `
    -Alias @(
        '*') `
    -Function @(
          'Invoke-MyMethod1',
          'Something-MyMethod2')
# then in your profile
Import-Module "MyMethod"
