要检查模块是否存在,我尝试了以下方法:

try {
    Import-Module SomeModule
    Write-Host "Module exists"
} 
catch {
    Write-Host "Module does not exist"
}

输出是:

Import-Module : The specified module 'SomeModule' was not loaded because no valid module file was found in any module directory.
At D:\keytalk\Software\Client\TestProjects\Export\test.ps1:2 char:5
+     Import-Module SomeModule
+     ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ResourceUnavailable: (SomeModule:String) [Import-Module], FileNotFoundException
    + FullyQualifiedErrorId : Modules_ModuleNotFound,Microsoft.PowerShell.Commands.ImportModuleCommand

Module exists

我确实得到了一个错误,但没有抛出任何异常,所以我们Module exists最终看到,虽然SomeModule不存在.

是否有一种好方法(最好不会产生错误)来检测系统上是否安装了PowerShell模块？
