未捕获的TypeError：$ export不是函数
我遇到某种Babel版本冲突。以下是获取错误的步骤：
我安装了keystonejs CMS，并导航到登录页面，这是一个reactjs构建。一切正常。
然后，我安装了使Webpack热模块更换正常工作（HMR）所需的一切。这也很好。
但是，在安装必需的babel软件包以使webpack HMR正常工作之后，运行良好的梯形登录页面会抛出上述TypeError。
为了安装必需的HMR软件包，我将依赖项从有效的HMR示例复制到了package.json文件中。然后我就跑了
npm install
这是我对项目的依赖关系（仅babel / react / webpack）：
"babel-cli": "^6.10.1",
"babel-core": "^6.10.4",
"babel-eslint": "^8.2.3",
"babel-loader": "^7.1.1",

"webpack": "^4.8.3",
"webpack-dev-middleware": "^3.1.3",
"webpack-hot-middleware": "^2.12.1",

似乎这里存在某种冲突，我不确定如何进一步解决问题。 任何帮助表示赞赏。
