Error: Couldn‘t find preset “es2015“ relative to directory

vue引入element-ui，运行时报了这个错误

复制代码

 @ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev-server ./src/main.js

按照element-ui中的步骤把.babelrc 文件内容从

复制代码

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

更改为了

复制代码

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

然后运行时就报了这个问题

解决方案：

安装es2015 工具

复制代码

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