我使用webpack作为模块捆绑器和babel进行转换。 我当前的npm版本是3.10.9，节点版本是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'），不能在mobx@4.0.0中使用
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/以获取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。例如：
无效：
{ presets: [{option: value}] }
有效：
{ presets: [['presetName', {option: value}]] }

请帮忙。
答案 0 :(得分：1)
首先，首先从.babelrc删除mobx预设。
{
"presets": ["mobx"]
}
然后npm i --save-dev babel-plugin-transform-decorators-legacy并添加以下.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0开始的babel-preset-mobx，我认为它不稳定。
