我的应用程序在Meteor React.js tutorial中崩溃(下面).我似乎无法找到问题,代码完全来自教程.救命！

Your application is crashing. Waiting for file change.

简单待办事项,react.html

<head>
  <title>Todo List</title>
</head>

<body>
  <div id="render-target"></div>
</body>

简单待办事项,react.js

if (Meteor.isClient) {
  // This code is executed on the client only

  Meteor.startup(function () {
    // Use Meteor.startup to render the component after the page is ready
    React.render(<App />,document.getElementById("render-target"));
  });
}

App.jsx

// App component - represents the whole app
App = React.createClass({
  getTasks() {
    return [
      { _id: 1,text: "This is task 1" },{ _id: 2,text: "This is task 2" },{ _id: 3,text: "This is task 3" },{ _id: 4,text: "This is task 4" },{ _id: 5,text: "This is task 5" }
    ];
  },renderTasks() {
    return this.getTasks().map((task) => {
      return <Task key={task._id} task={task} />;
    });
  },render() {
    return (
      <div className="container">
        <header>
          <h1>Todo List</h1>
        </header>

        <ul>
          {this.renderTasks()}
        </ul>
      </div>
    );
  }
});

Task.jsx

// Task component - represents a single todo item
Task = React.createClass({
  propTypes: {
    // This component gets the task to display through a React prop.
    // We can use propTypes to indicate it is required
    task: React.PropTypes.object.isRequired
  },render() {
    return (
      <li>{this.props.task.text}</li>
    );
  }
});

解决方法

哇,忘了在文件名末尾添加“x”.应该是“simple-todos-react.jsx”.如果错误消息更清楚,将有所帮助.
