Webpack-无法读取未定义的属性'func'（var func = _react.PropTypes.func）

Question

运行应用程序时，出现标题问题中提到的错误。注意：我没有在组件中使用propTypes，我知道propTypes在新React中的单独库中。但是不知道这个错误是从哪里产生的。大概有模块版本的东西吗？我将为package.json和webpack.config.js提供代码。...

这里有package.json个依赖项和devDependencies：

"devDependencies": {
    "babel-core": "^6.26.3",
    "babel-eslint": "^8.2.5",

  }

这是webpack.config.js：

'use strict';

const path = require('path');
const webpack = require('webpack');

const CleanWebpackPlugin = require('clean-webpack-plugin');

};

module.exports = (env, options) => {

            new MiniCssExtractPlugin({

            }),
            new webpack.LoaderOptionsPlugin({

            }),
            new webpack.HotModuleReplacementPlugin(),
