PowerShell“在创建管道时发生错误" #Requires -Version 3.0 [英] PowerShell "an error occurred while creating the pipeline" #Requires -Version 3.0

问题描述

尝试使用任何#Requires命令时，例如:

When attempting to use any of the #Requires commands, for example:

#Requires -Version 3.0 

他们输入以下文字错误:

They error with the text:

创建管道时发生错误. + CategoryInfo:未指定:(:) []，ParentContainsErrorRecordException + FullyQualifiedErrorId:RuntimeException

An error occurred while creating the pipeline. + CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : RuntimeException

我已经在ISE和控制台上对此测试了相同的结果，我的版本如下:

I've tested this on ISE and the Console with the same results, my versions are below:

Name                           Value
----                           -----
PSVersion                      5.1.14409.1012
PSEdition                      Desktop

推荐答案

发布问题前的最终测试提供了答案:

My final test before posting the question provided the answer:

似乎'#Requires'命令旨在不符合要求的情况下破坏脚本，而不是发布错误，并且在一行上对其进行测试将导致错误.

It seems the '#Requires' commands are designed to break out of the script if it doesn't meet the requirements rather than posting an error, and testing it on a single line will result in an error.

要进行测试，请找到您的PowerShell版本(例如5.1)，然后将以下转置5.1与您的(主要.次要)版本一起保存:

To test, find your PowerShell version (e.g. 5.1) and save the following transposing 5.1 with your (major.minor) version:

#Requires -version 5.1
$PSVersionTable.PSVersion
Read-Host

这将在ISE和控制台上都可以使用，即使使用PowerShell运行"也可以提供输出.

This will work on both ISE and the Console, providing an output even if 'Run with PowerShell'.

• 单独使用#Requires-(任意)行将显示错误.
  • 在ISE中，只要附带另一行代码，运行选择"将起作用.
  • Using the #Requires -(anything) line on its own will display the error.
    • In ISE 'Run selection' will work, as long as it's accompanied by another line of code.
