Question

我正在尝试建立出租车预订应用程序。从我得到错误 undefined is not an object (evaluating'_react2.Proptypes.store')。我在之前的问题中尝试了所有其他解决方案，但没有用。对此有任何帮助表示赞赏。

import React, { Component, PropTypes} from "react";
import { Router } from "react-native-router-flux";
import scenes from "../routes/scenes";



import { Provider } from "react-redux";

export default class AppContainer extends Component{
static propTypes =  {
        store: PropTypes.object.isRequired
}
render(){
    return(
        <Provider store = {this.props.store}>
            <Router scenes = {scenes} />
        </Provider>
        )
}
}

的package.json

"private": true,

"start": "node node_modules/react-native/local-cli/cli.js start",

自从版本16.0.0向前反应之后，不能像在第一行那样从React本身获取prop类型。您需要执行以下操作;

npm install prop-types --save
添加以下导入并从第一行中删除PropTypes： import PropTypes from 'prop-types';

在此之后，它应该像魅力一样。

undefined不是一个对象（评估'_react2.Proptypes.store'）？
