同学你好，单凭这点信息，我定位不出来问题呀，是不是80端口冲突了

  你好老师，我再梳理一遍，看看能不能避免这个令人郁闷的报错～

• 提问者 Siio #2

  当我在server/utils.js里面添加renderRoutes(react-router-config)，代码：{renderRoutes(routes)}时，会报错误：You should not use <Switch> outside a <Router>，我里面也手动引入Switch。。。

• 提问者 Siio #3

  突然运行正常了。。
  解决的过程：我在yarn安装react-router-config@^4.4.0-beta.6时，它提示我安装react-router@4.4.0-beta.1，直接导致了报错！
  remove react-router@4.4.0-beta.1 就不报错了，对这块还是理解不够。。。
  尴尬～
