這兩天準備親手搭建一個react專案，本以為會很順利，沒想到遇到了很多相容性的問題。剛開始遇到webpack和babel的版本不相容，之後使用webpack-dev-server搭建伺服器遇到安裝的webpack和webpack-dev-server版本不相容的問題。作為一名前端小白的我表示心很累。

現象：安裝webpack之後執行正常，再安裝不同版本的webpack-dev-server，出現了許多不同的錯誤，以下列舉兩種錯誤。

解決方法：嗯。。。因是版本不相容的問題，解決方法還是改變webpack和webpack-dev-server安裝版本，還有babel的版本。。。
webpack.config.js

const path = require('path')

module.exports = {
    entry: path.join(__dirname, 'src/index.js'),
    output: {
        path: path.join(__dirname, './dist'),
        filename: 'bundle.js'
    },
    module: {
        rules: [{
            test: /\.js$/,
            use: ['babel-loader?cacheDirectory=true'
 
],
            exclude: path.resolve(__dirname, 'node_modules')
        }]
    },
    devServer: {
        port: 8080,
        contentBase: path.join(__dirname, './dist'),
        historyApiFallback: true,
        host: '127.0.0.1'
    }
}
