我正在通过创建Blogpost应用来练习React Redux。 创建新的帖子组件时遇到问题。 我已经安装了axios,redux-promise。 我已经安装了react-router 4.0.0,react-router-dom 4.2.2,redux-form 6.6.3
1。这是我的src / index.js
import React from "react";
import ReactDOM from "react-dom";
import { Provider } from "react-redux";
import { createStore, applyMiddleware } from "redux";
import { BrowserRouter, Route, Switch } from "react-router-dom";
import promise from "redux-promise";
import reducers from "./reducers";
import PostIndex from "./components/posts_index";
import PostsNew from "./components/posts_new";
const createStoreWithMiddleware = applyMiddleware(promise)(createStore);
ReactDOM.render(
<Provider store={createStoreWithMiddleware(reducers)}>
<BrowserRouter>
<div>
<Switch>
<Route path="/posts/new" component={PostsNew} />
<Route path="/" component={PostIndex} />
</Switch>
</div>
</BrowserRouter>
</Provider>,
document.querySelector(".container")
);
2。这是我的动作/index.js
import axios from "axios";
export const FETCH_POSTS = "FETCH_POSTS";
const ROOT_URL = "http://reduxblog.herokuapp.com/api";
const API_KEY = "?key=SHUVRO1234";
export function fetchPosts() {
const request = axios.get(`${ROOT_URL}/posts${API_KEY}`);
return {
type: FETCH_POSTS,
payload: request
};
}
3。这是reducers / index.js
import { combineReducers } from "redux";
import { reducer as formReducer } from "redux-form";
import PostsReducer from "./reducer_posts";
const rootReducer = combineReducers({
posts: PostsReducer,
form: formReducer
});
export default rootReducer;
4。这是动作减少器
import _ from "lodash";
import { FETCH_POSTS } from "../actions";
export default function(state = {}, action) {
switch (action.type) {
case FETCH_POSTS:
return _.mapKeys(action.payload.data, "id");
default:
return state;
}
}
5。这是显示错误的posts_new组件
import React, { Component } from "react";
import { Field, reduxForm } from "redux-form";
class PostsNew extends Component {
renderTitleField(field) {
return (
<div>
<input type="text" {...field.input} />
</div>
);
}
render() {
return (
<form>
<Field name="title" component={this.renderTitleField} />
</form>
);
}
}
export default reduxForm({ form: "PostsNewForm" })(PostsNew);
这是控制台中的错误

请帮助我解决此错误
答案 0 :(得分:1)
只需运行“ npm i hoist-non-react-statics” 希望对您有帮助
