我已经和yeoman开始了一个react全栈项目。有一个观察程序，当我对玉文件进行更改时，它会更新玉文件，而不会保存。正如你所能想象的，我的控制台看起来是这样的：
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
[BS] File changed: build/content/index.jade
然而，无论何时进行更改，Webstorm 10:的Run部分都会出现错误

每当文件更改时，Run（运行）窗口中就会弹出此消息，但它似乎不会导致更新文件的实际问题。
你经历过这个错误吗？如何防止出现此错误，以及为什么它与acorn.js有关？
您应该从位于*.jade文件开头的代码中删除---
例如，你可以在index.jade:中看到它
