我尝试将Webpack和babel分别升级到4、7，但是无法正常工作。另外，官方文档对升级没有太大帮助

我正在关注问题

编译器错误：找不到模块’@ babel / core’@多主体时出错

我正在使用的依赖项：

"babel-core": "^6.26.3",
"babel-eslint": "^9.0.0",
"babel-loader": "^8.0.0",
"babel-plugin-transform-class-properties": "^6.24.1",
"babel-plugin-transform-object-rest-spread": "^6.26.0",
"babel-polyfill": "^6.26.0",
"babel-preset-env": "^1.7.0",
"babel-preset-react": "^6.24.1",
"webpack": "^4.15.0",
"webpack-cli": "^3.0.8",
"webpack-dev-server": "^3.1.4"

如果需要更多详细信息，请告诉我。
