babel-loader与babel-core的版本对应关系

babel-loader 8.x对应babel-core 7.x
babel-loader 7.x对应babel-core 6.x
如何解决
1、 卸载旧的babel-core
npm un babel-core
2、 安装新的babel-core
npm i -D @babel/core
3、 卸载旧的babel-preset
npm un babel-preset-env
npm un babel-preset-stage-0
4、 安装新的babel-preset
npm i @babel/preset-react
npm i @babel/preset-env
npm i babel-preset-mobx
5、 卸载旧的babel-plugin
npm un babel-plugin-transform-runtime
6、 安装新的babel-plugin
npm install --save-dev @babel/plugin-proposal-object-rest-spread
npm install --save-dev @babel/plugin-transform-runtime
npm install --save @babel/runtime
7、 修改.babelrc文件

{
    "presets": ["@babel/preset-env", "@babel/preset-react", "mobx"],
    "plugins": [
        "@babel/plugin-proposal-object-rest-spread",
        "@babel/plugin-transform-runtime"
