【问题描述】：
我在为 Visual Studio Team Services（以前的 Visual Studio Online）中的自动构建设置 NPM 任务时遇到问题。有两个问题：
- 缓存锁定错误（如下所示）。
- 速度非常慢——十几个包裹需要 45 多分钟。
我添加了 --cache 参数，但这似乎没有帮助。
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：

感谢任何建议...
当前配置：

【问题讨论】：
-
我似乎找不到关于 --dev 和 --cache 标志的文档，你能给我一些指点吗？
-
老实说，这些标志不应该是必需的 - 请参阅下面的答案。在全球范围内更新 NPM 就成功了。
-
我明白了。我实际上是在尝试避免在每次构建时下载所有 node_modules，我认为这个 --cache 标志会有所帮助。我想全局安装 npm 解决了您的锁定文件问题，但没有解决 node_modules 重新下载问题？
-
还试图不必在每次构建时都安装 node_modules 文件夹，并且不希望它们成为工件的一部分。你知道怎么做吗？
-
@Philip - 不知道，但我发现 MS 构建支持团队非常有帮助。在构建页面中，单击帮助，然后点击支持链接，直到您记录工单。他们反应灵敏。
