npm run eject之后（为了更改webpack.config，这是必需的），在应用编译期间我遇到了以下问题：Cannot find module 'babel-plugin-transform-decorators-legacy'。
我尝试了以下描述的多种变体： Cannot find module '@babel/plugin-transform-react-jsx-source' when running React App
（最流行的方法之一是删除节点模块，然后再次执行yarn install-没有帮助）
如何解决该问题？
这是我的.babelrc文件：
{
"presets": [
[
"es2015",{
"modules": false
}
],"react","stage-2","react-app","babel-preset-expo"
],"plugins": [
"syntax-dynamic-import","transform-decorators-legacy","transform-object-rest-spread","react-hot-loader/babel"
],"env": {
"test": {
"plugins": [
"transform-decorators-legacy","istanbul"
]
}
}
}
还有我的package.json：

更新
我还完成了yarn add babel-plugin-transform-decorators-legacy-没用。
