{
    "presets": [
      ["env", {
        "targets": {
          "browsers": ["> 2%"]
        },
        "useBuiltIns": true
      }]
    ],
      "plugins": [
        [
          "component",
          {
            "libraryName": "element-ui",
            "styleLibraryName": "~theme"
          },
          {
            "libraryName": "@xiaoe/b-e-commerce",
             "style": true
         },
         "@xiaoe/b-e-commerce"
        ]
      ]
    }
