如何在Visual Studio Team Services构建代理中正确运行NPM安装

Question

我在为Visual Studio Team Services（以前的Visual Studio Online）中的自动构建设置NPM任务时遇到了问题。有两个问题：

1. 缓存锁定错误（如下所示）。
2. 这是非常缓慢的 - 大约十几个包裹可以超过45分钟。

我添加了--cache参数，但似乎没有帮助。

npm install --dev --cache $(Agent.BuildDirectory)\b

二进制文件夹似乎是缓存的正确位置，但老实说，我不确定。这里有一些文档：

我感谢任何建议......

当前配置：

重新安装NPM解决了我的问题：

npm install npm -g

具体来说，我将带圆圈的任务添加到我的构建中：
