Question

使用

中自述文件中的示例

https://github.com/ReactTraining/react-router/tree/master/packages/react-router-redux

我在索引中创建了这个布局：

// attach the redux dev tools extension for Chrome
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

// apply router logic as middleware
const history = createHistory();
const router_mw = routerMiddleware(history);


// second arg to createStore is the inital redux store state
const store = createStore(
  reducers,
  initialState,
  composeEnhancers(
    applyMiddleware(
      ReduxPromise,
      ReduxThunk,
      router_mw
    )
));

// --> add routes for logs, opsec, etc. later
ReactDOM.render(
  <Provider store={ store }>
    <ConnectedRouter history={ history }>  // <- error here
      <div>
        <Route exact path="/" component={ LoginScreen } />
        <Route path="/comp1" component={ comp1 } />
        <Route path="/comp2" component={ comp2 } />
      </div>
    </ConnectedRouter>
  </Provider>
  , document.getElementById('root')
);

任何编译它的尝试都会抱怨ConnectedRouter入口点中的{history}：

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in. Check your code at index.js:52.

我错过了什么？这是react-router-redux改造 - 返回react-router（并将ConnectedRouter更改为BrowserRouter），一切正常。

我使用react-router-dom@4.2.2并遇到同样的问题，直到将react-router-redux更新为^5.0.0-alpha.9。

如果您使用react-router-dom@4，则应使用react-router-redux@5，react-router-redux repo中说明了这一点：

react-router-redux的下一个版本将是5.0.0，并将与react-router 4.x兼容。目前正在积极开发over there。随意帮忙！

react-router-redux历史记录未被接受（来自示例代码）
