当我导航到 localhost:3000/signup 时，该组件未显示是因为反应路由器已更新到 v4 并且您在反应中路由的方式现在已经改变了吗？

我有我的main.js档案

import Signup from '../imports/ui/Signup';

import
const routes = (
  <Router history={browserHistory}>
    <Route path="/signup" component={Signup}/>
  </Router>
);

注册组件

import React from 'react';

export default class Signup extends React.Component {
  render() {
    return <p>Signup</p>
  }
}

我正在使用反应路由器 v4，也使用 Meteor。

React Router v4 是对 React Router 的重写，因此您必须阅读新的 API 并相应地调整您的代码。我建议浏览所有可以在此处找到的示例。这是与您的代码相似的基本示例。你会注意到的最重要的事情是你不再有一个集中的路由配置。相反，当你需要它们时，你会动态地渲染 `` 。

import React from 'react'
import {
  BrowserRouter as Router,
  Route,
  Link
} from 'react-router-dom'

const BasicExample = () => (
  <Router>
    <div>
      <ul>
        <li><Link to="/">Home</Link></li>
        <li><Link to="/about">About</Link></li>
        <li><Link to="/topics">Topics</Link></li>
      </ul>

      <hr/>

      <Route exact path="/" component={Home}/>
      <Route path="/about" component={About}/>
      <Route path="/topics" component={Topics}/>
    </div>
  </Router>
)

const Home = () => (
  <div>
    <h2>Home</h2>
  </div>
)

const About = () => (
  <div>
    <h2>About</h2>
  </div>
)

const Topics = ({ match }) => (
  <div>
    <h2>Topics</h2>
    <ul>
      <li>
        <Link to={`${match.url}/rendering`}>
          Rendering with React
        </Link>
      </li>
      <li>
        <Link to={`${match.url}/components`}>
          Components
        </Link>
      </li>
      <li>
        <Link to={`${match.url}/props-v-state`}>
          Props v. State
        </Link>
      </li>
    </ul>

    <Route path={`${match.url}/:topicId`} component={Topic}/>
    <Route exact path={match.url} render={() => (
      <h3>Please select a topic.</h3>
    )}/>
  </div>
)

const Topic = ({ match }) => (
  <div>
    <h3>{match.params.topicId}</h3>
  </div>
)

export default BasicExample
