【问题描述】：
我使用 webpack 作为模块捆绑器和 babel 进行转译。 我当前的 npm 版本是 3.10.9，node 版本是 v6.9.2。

当我编译时，我得到以下问题。
不推荐使用默认导出 (import mobx from 'mobx')，并且在 mobx@4.0.0 中不起作用
请改用import * as mobx from 'mobx'

ReferenceError: [BABEL] D:\mgm\dmp\fe-react\webpack.config.babel.js: 未知选项：base.Reaction。查看http://babeljs.io/docs/usage/options/ 了解有关选项的更多信息。
此错误的常见原因是存在没有相应预设名称的配置选项对象。示例：
无效：
{ presets: [{option: value}] }
有效的：
{ presets: [['presetName', {option: value}]] }

请帮忙。
【问题讨论】：
-
所以...您是否按照错误中的明确说明进行操作？
-
@JaromandaX 是，但没有帮助。
-
那么，你在
D:\mgm\dmp\fe-react\webpack.config.babel.js中改变了什么 -
注意：第一个“错误”只是一个警告（目前）——问题是
Unknown option: base.Reaction -
webpack 配置。 {test: /.js?$/,exclude: /node_modules/, 使用: [{ loader: "babel-loader", options: { presets: [ ['env', { modules: false, targets: { browsers: [ 'last 2 versions', 'safari >= 7', 'ie >= 10'] } }], 'stage-0', 'react' ], cmets:true } }] },
