解决Vue按需引入element-ui报错

按照官方文档里的步骤配置,出现如下报错

Error: Cannot find module 'babel-preset-es2015'

修改babel.config.js配置

将 "presets": [["es2015", { "modules": false }]]

改为 ["@babel/preset-env", {"modules": false}]

详细配置如下

{
    // "presets": [["es2015", { "modules": false }]],//错
    ["@babel/preset-env", {"modules": false}],//对
  "plugins": [
    [
      "component",
      {
        "libraryName": "element-ui",
        "styleLibraryName": "theme-chalk"
      }
    ]
  ]
}
