新建的项目，安装了babel-plugin-transform-vue-jsx之后，报错

[wqcstrong]

安装了babel-plugin-transform-vue-jsx并且按照文档在vue-cli3脚手架新建的项目的babel.config.js中修改成如下配置：

module.exports = {
  presets: [
    '@vue/app',
    'env'
  ],
  plugins: ["transform-vue-jsx"]
}

然后再用vue add element 安装 elementUI， babel.config.js被改成了这样：

module.exports = {
  "presets": [
    "@vue/app",
    "env"
  ],
  "plugins": [
    "transform-vue-jsx",
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}


最后，起服务`npm run serve`, 点击查看

@jikkai 可否看一下？

@babel/preset-env is in @vue/babel-preset-app's features.
