我在VSTS中有一个构建管道，它包含以下步骤
现在我想添加几个额外的步骤来运行npm（Angular）测试。我有一个package.json，它定义了所有典型的命令，包括test和test-single-run。它引用了jasmine-core，karma等。如果有人想看到它们，我可以发布完整的文件。从我机器上的命令行，我可以运行npm run test-single-run命令，它可以正常运行并执行测试。
我在第4步，2 npm步骤和另一个发布测试结果之后向上面的构建管道添加了3个步骤（不知道是否/如何使用2个不同的源，但这不是我现在的问题）
第一个npm步骤运行命令install，并将包含package.json的Working文件夹作为src / Cranalytics。
第二个npm步骤使用run test-single-run的命令行参数运行custom，并且还指定了相同的Working文件夹。
第一个npm命令运行没有任何错误，我可以看到它拉下了一堆东西。第二个错误如下：
C:\Windows\system32\cmd.exe /D /S /C ""C:\Program Files\nodejs\npm.cmd" run test-single-run"
> Cranalytics@1.0.0 test-single-run d:\a\1\s\src\Cranalytics
> karma start wwwroot/karma.conf.js --single-run
