Question

在windirstat上安装ilmerge和Chocolatey时，我遇到以下错误。我怀疑PowerShell 3.0中的＆符号行为发生了变化。

Running powershell -NoProfile -ExecutionPolicy unrestricted -Command "& import-module -name  'C:\NuGet\chocolateyInstall\helpers\chocolateyInstaller.psm1'; & 'C:\NuGet\lib\ilmerge.2.10.526.4\tools\chocolateyInstall.ps1'". This may take awhile and permissions may need to be elevated, depending on the package.
ilmerge did not finish successfully. Boo to the chocolatey gods!

[ERROR] The expression after '&' in a pipeline element produced an invalid object. It must result in a command name, script block or Command
Info object.

Answer 1

问题不在于＆符号行为我不得不用$oc = Get-Command 'Write-Host' | ?{$_.ModuleName -eq 'Microsoft.PowerShell.Utility'}替换$oc = Get-Command 'Write-Host' -Module 'Microsoft.PowerShell.Utility'以及为Write-Error包装器做类似的替换。

Answer 2

如何使用-version 1.0或2.0参数启动PowerShell？然后运行上面的命令，看看是否有任何区别。

在命令行

PowerShell -version 2.0

Powershell 3.0中的＆符号行为是否发生了变化？
