Azure App / Web服务上出现"npm install“错误: EPERM:不允许操作，lchown

Question

在为Node 12 LTS配置的Linux Azure App / Web Service上，在将代码资产上载到/home/site/wwwroot/ (其中包括一个package.json文件)之后，我以root身份运行npm install。我得到了下面进一步显示的异常。

同样的异常发生在两个不同的Azure App / Web Services上，一个用于UI，另一个用于API (因此是两个不同的代码集)。但错误模式是相同的：

它不能更改/home/site/wwwroot/node_modules/[...]/build-optimizer/node_modules/.bin/下目录的所有权，只是因为.../.bin/子目录本身从未创建过。

同样，在这两种情况下，我都是以root身份运行npm install。

有什么想法吗？请看下面的内容，谢谢。

也有同样的问题。感谢semkeijsper的评论，我的解决方案是:在package.json中：

npm install

修改为：

"npm cache clean --force && npm install"
