如果你在PowerShell Core中无法使用Publish-Module发布NuGet模块

可以检查一下是不是因为你的.NET Core CLI正在使用非英语输出。Publish-Module需要根据.NET Core CLI的输出来匹配生成的NuGet包的位置。

在Publish-Module调用后面加上-Verbose参数即可显示.NET Core CLI的输出信息，例如

PS> Publish-Module -Path:$RedistDir -Repository:$RepositoryName -NuGetApiKey:$ApiKey -Verbose

请注意35行的输出。如果你发现.NET Core CLI正在输出非英语文本，你需要转到PowerShellGet报错的模块中（如此处的 C:\program files\powershell\7-preview\Modules\PowerShellGet\PSModule.psm1），搜索以下文本

"Successfully created package '(.*.nupkg)'"

并将其替换为当前系统语言对应的文本，如

'已成功创建包“(.*.nupkg)”'

最后重新打开PowerShell Core并进行模块发布即可。

此问题在PowerShell/PowerShellGetv2#510中提及，但在发布的PowerShell Core 7.0中仍然存在。
