使用PS在appveyor中使用twine上传

Question

在我的AppVeyor部署脚本中，我使用ps: >-命令根据存储库分支进行部署：

- ps: >-
    If ($env:APPVEYOR_REPO_BRANCH -eq 'devel') { 
        echo not deploying on devel # twine upload --skip-existing -r test dist/*
    }
    ElseIf ($env:APPVEYOR_REPO_BRANCH -eq 'deploy') {  
        twine upload --skip-existing dist/*
    }
    Else {
        echo not deploying on other branches
    }

这将在AppVeyor构建中创建如下错误消息：

twine : 
At line:2 char:5
+     twine upload --skip-existing dist/*
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

并且构建显示为失败。奇怪的是，这些包被上传到pypi并可供下载。因此，该命令实际上执行得很好，但由于此异常，构建显示为失败。如果错误消息能提供更多的信息...

下面是在AppVeyor (https://ci.appveyor.com/project/mzwiessele/gpy/build/1.0.361/job/baimi4og179tk3p8)上使用更简单的脚本和完整输出运行的另一次运行

if ($env:APPVEYOR_REPO_BRANCH -eq 'deploy') {  
    twine upload --skip-existing dist/*
} else {
    echo not deploying on other branches
}
twine : 
At line:2 char:5
+     twine upload --skip-existing dist/*
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError
