我正在尝试使用最新的react-router-redux(v5),但它永远不会渲染我的组件。获得渲染的唯一一个是home(/)。我的其他路线组件中的断点永远不会被击中。我甚至删除了connect(mapStateToProps,mapDispatchToProp)(Component)调用(并且只做了一个非常简单的组件) - 仍然没有渲染。
浏览器栏中的路线发生变化。如果我只是在index.js中导入项目,摆脱所有的路由和导航,它渲染得很好。
我几乎完全复制了
中的文档https://github.com/ReactTraining/react-router/tree/master/packages/react-router-redux
除非有一些我不知道的不兼容性?

此外,我可以看到正在为路由更改分派操作:

因此,太多的时间没有过去,我忘了解决方案是什么:
请确认您的反映路由器版本以及您所淹没的文档版本是否正确。
我正在阅读一个过时的文档网站,几乎使用最新的反应/反应路由器。
答案 0 :(得分:2)
我认为当我升级到react-router v4时我遇到了类似的问题,我在我的根组件中使用withRouter
解决了这个问题。
export default (
<Router history={history} onUpdate={logPageView}>
<Root>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
<Route path="/calculator" component={Calc} />
<Route path="/how-it-works" component={HowItWorks} />
<Route path="/get-landed" component={GetLanded} />
<Route status={404} path="*" component={Home} />
</Switch>
</Root>
</Router>
);
如果您没有根组件,请尝试路由的所有组件。
import { withRouter } from 'react-router'
class Root extends React.Component {
...
}
// Create a new component that is "connected" (to borrow redux
// terminology) to the router.
export default const RootWithRouter = withRouter(Root)
