2、错误原因

将.babelrc文件中的内容

{
      "presets": [
        ["env", {
          "modules": false,
          "targets": {
            "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
          }
        }],
        "stage-2"
      ],
      "plugins": ["transform-vue-jsx", "transform-runtime"]
    }

改为

{
      "presets": [["es2015", { "modules": false }]],
      "plugins": [
        [
          "component",
          {
            "libraryName": "element-ui",
            "styleLibraryName": "theme-chalk"
          }
        ]
      ]
    }

3、解决办法

执行一下下面命令：

npm install --save-dev babel-preset-es2015

F:\WebstormProjects\euw\esa>npm install --save-dev babel-preset-es2015
    npm WARN deprecated babel-preset-es2015@6.24.1: ????  Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update!
