grunt serve：并发：服务器因警告而中止

Question

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（... 以上的所有内容都以 OK 传递）：

...
Running "wiredep" task

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

这是我的Gruntfile.js：

// Generated on 2014-06-16 using generator-angular 0.9.0-1

Answer 1

实际上，我的 SCSS 没有语法错误，这是因为我全局安装了 compass (npm -g)，而它需要作为 Ruby gem 安装：

gem install compass

Answer 2

我不是专家，但我发现一旦本地服务器运行，它将允许 scss 或其他任何内容中出现 lint 错误，然后一旦您停止服务器并尝试重新启动，它将给出此错误，直到您修复 scss 错误。您可以使用 grunt check 然后解决它们并重试。 9/10 这就是我的服务器无法重启的原因。

Answer 3

它是在 SCSS 文件中导入的。试试

grunt serve --force
