我的项目突然停止使用 grunt。不幸的是，我有一段时间没有将我的更改提交到 git 中，所以我不知道有什么不同。

当我运行 grunt server --verbose 时，我得到以下输出(... 上面的所有内容都通过 OK):

...

因此，当尝试执行任务 concurrent:server 时，grunt 会中止。在这个任务中，compass:server 任务被执行(参见下面的 Gruntfile.js)。所以，它一定与罗盘有关，但我不确定这行 Files: [no src] -> server 是否可以为问题提供更多提示。

这是我的 Gruntfile.js:

最佳答案

愚蠢的我!

对于遇到相同问题的任何人:

我的 SCSS 文件中有一些导入错误。在 grunt 的实时重新加载期间，它会告诉您有问题。但是在 grunt serve 的启动过程中它只是中断并且什么都不告诉你。因此，请检查您的 SCSS 文件的导入和语法。
