webpack.config.js 中配置babel-loader

{
    exclude: /node_modules/,
    test: /\.(js)$/,
    loader: 'babel-loader'
}

.babelrc 配置使用babel-preset-env进行转码

{
  "presets": ["env"]
}

babel-core也安装了

在build的时候报错了

    ERROR in ./src/core/index.js
Module build failed (from ./node_modules/_babel-loader@8.0.2@babel-loader/lib/index.js):

请大神赐教，是少了什么插件吗？
