我在使用npm run release出现了下面的问题，怎么解决

Hash: 223396e11ea7f486fa19

Version: webpack 4.19.0

WARNING in configuration

The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.

You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/concepts/mode/

    mode: 'production',

    在webpack.config.js中加入一个这个，
    如果还报错，请看看版本问题

    npm uninstall babel-loader

    npm install babel-loader@7.1.5

    执行一下这两个命令

    你试试，我是这么解决的

    这个是成功的效果，注意一定要版本正确，并且不是在高版本存在的情况下，回答时期：16:59 2018/11/23

    本人也出现了该方法，经过半天的一步步改进，目前问题已经解决。解决方式为严格安装视频的版本走，并且不能实现重新添加，比如一步成功。

    如楼上两位的，一旦添加了新版，及时使用添加旧版，一样报错。

    我仔细对比了版本区别：

    相同部分：直接运行
    npm i babel-core babel-polyfill babel-preset-es2015 babel-preset-latest --save-dev --registry=https://registry.npm.taobao.org

    差异部分：指定运行如下
    npm i babel-loader@7.1.4 webpack@4.7.0 webpack-cli@2.1.2 --save-dev 

    最终效果如下：

    因为你安装的babel-loader的版本太高了，应该是8点几吧，改到7.1.5版就可以了。
