React Redux 路由器错误

Question

我正在尝试设置 Redux + React Router 应用程序。我认为问题出在 ImmutableJS 上，但我不明白如何解决它。

客户端.js

import { fromJS } from 'immutable'
import React from 'react'
import { render, unmountComponentAtNode } from 'react-dom'
import { AppContainer } from 'react-hot-loader'

import { Provider } from 'react-redux'
import { match, Router, browserHistory } from 'react-router'
import { syncHistoryWithStore } from 'react-router-redux'

import { createStore, combineReducers, compose, applyMiddleware } from 'redux'
import { routerReducer, routerMiddleware } from 'react-router-redux'

function createSelectLocationState(reducerName) {
  let prevRoutingState;
  let prevRoutingStateJS;

  return (state) => {
    const routingState = state.get(reducerName); // or state.routing

    if (!routingState.equals(prevRoutingState)) {
      prevRoutingState = routingState;
      prevRoutingStateJS = routingState.toJS();
    }

    return prevRoutingStateJS;
  };
}

function configureStore(history, initialState) {
  const reducer = combineReducers({
    routing: routerReducer
  });

  return createStore(
    reducer,
    initialState,
    compose(
      applyMiddleware(
        routerMiddleware(history)
      )
    )
  );
}

const initialState = fromJS(window.__INITIAL_STATE__);
const store = configureStore(browserHistory, initialState);
const history = syncHistoryWithStore(browserHistory, store, {
  selectLocationState: createSelectLocationState('routing')
});
const rootNode = document.getElementById('root');

const renderApp = () => {
  const routes = require('./routes');

  match({ history, routes }, (error, redirectLocation, renderProps) => {
    render(
      <AppContainer>
        <Provider store={store}>
          <Router {...renderProps} />
        </Provider>
      </AppContainer>,
      rootNode
    );
  });
};

// Enable hot reload by react-hot-loader
if (module.hot) {
  const reRenderApp = () => {
    try {
      renderApp();
    } catch (error) {
      const RedBox = require('redbox-react').default;

      render(<RedBox error={error} />, rootNode);
    }
  };

  module.hot.accept('./routes', () => {
    setImmediate(() => {
      // Preventing the hot reloading error from react-router
      unmountComponentAtNode(rootNode);
      reRenderApp();
    });
  });
}

renderApp();

我收到此错误：

未捕获的类型错误：state.get 不是函数

在state这个对象中

我用"react": "^15.3.2"，"redux": "^3.6.0"，"react-router": "^3.0.0"

更新 1 我现在使用combineReducers来自redux-immutable：

import {combineReducers} from 'redux-immutable'

但得到一个错误：

未捕获的类型错误：routingState.equals 不是函数

这里：

更新2

我修复了上述问题，但还有一个错误

我在此存储库中发布的所有代码

Answer 1

问题仍然存在src/index.js于route.js 的声明文件中require。

当您的require es6模块具有时default，您必须使用required 模块中的默认值。就像是，

const routes = require('./routes').default;

这解决了您的问题，无需对 git 存储库进行任何其他更改。
