Question

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。救命啊！

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>
    );
  }
});

哇，忘了添加＆＃34; x＆＃34;到文件名的末尾。应该是＆＃34; simple-todos-react.jsx＆＃34;。如果错误消息更清楚，将会有所帮助。
