router.push Cannot read property '_normalized' of null

解决办法：router下的index.js添加push重写:

//重写routerPush以免产生router.push Cannot read property '_normalized' of null的错误
const routerPush = Router.prototype.push;
Router.prototype.push = function push(location) {
  return routerPush.call(this, location).catch(error => error)
}
