在Codemirror上显示CoffeeScript Lint

Question

我之前在Codemirror上玩过CoffeeScript，我不知道为什么但linting不能与Codemirror一起使用。即使是随Codemirror包提供的lint也不适用于我。

我做错了什么，我该如何解决这个问题？

// Initialize CodeMirror editor
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
  mode: "text/x-coffeescript",
  tabMode: "indent",
  styleActiveLine: true,
  lineNumbers: true,
  lineWrapping: true,
  autoCloseTags: true,
  foldGutter: true,
  dragDrop: true,
  lint: true,
  gutters: ["CodeMirror-lint-markers", "CodeMirror-linenumbers", "CodeMirror-foldgutter"]
})

.CodeMirror {
  width: 100%;
  height: auto;
}
