【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。

包.json

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' D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\file\logger.js:41 抛出新的构造函数（this._buildMessage（msg））； ^

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]]

有关预设配置的更多详细信息，请参阅http://babeljs.io/docs/plugins/#pluginpresets-options。 在 Logger.error (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\file\logger.js:41:11) 在 OptionManager.mergeOptions (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\file\options\option-manager.js:226:20) 在 OptionManager.init (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\file\options\option-manager.js:368:12) 在 File.initOptions (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\file\index.js:212:65) 在新文件 (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\file\index.js:135:24) 在 Pipeline.transform (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\transformation\pipeline.js:46:16) 在 Object.transformFileSync (D:\mgm\dmp\fe-react\node_modules\babel-core\lib\api\node.js:152:10) 编译时 (D:\mgm\dmp\fe-react\node_modules\babel-register\lib\node.js:118:20) 在装载机 (D:\mgm\dmp\fe-react\node_modules\babel-register\lib\node.js:144:14) 在 Object.require.extensions.(匿名函数) [as .js] (D:\mgm\dmp\fe-react\node_modules\babel-register\lib\node.js:154:7)

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 ] ,

【参考方案1】：

首先，从.babelrc 中删除 mobx 预设。

  "presets": ["mobx"]

然后npm i --save-dev babel-plugin-transform-decorators-legacy 并在下面添加.babelrc 配置。

  "presets": ["react", "env", "stage-2"],
  "plugins": [
    "transform-decorators-legacy", // must on the top of plugins array.
    ... ...
  ]

最后，你必须删除GitHub上那个0开头的babel-preset-mobx，我认为它是不稳定的。
