搜了下资料说删除vue-cli中.babelrc下的一个配置可以引用其他标准的模块包
现在有个拼音库想打包，就试了下

{
  "presets": [
    ["env", {
      "modules": false, //删除这行
      "targets": {
        "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
      }
    }],
    "stage-2"
  ],
  "plugins": ["transform-runtime"],
  "env": {
    "test": {
      "presets": ["env", "stage-2"],
      "plugins": ["istanbul"]
    }
  }
}

可是并不可行，整个项目都报错

133:3 Uncaught ReferenceError: exports is not defined
    at eval (133:3)
    at Object.<anonymous> (app.js:1644)
    at __webpack_require__ (app.js:689)
    at fn (app.js:110)
    at Object.<anonymous> (app.js:2886)
    at __webpack_require__ (app.js:689)
    at app.js:790
    at app.js:793

有什么解决方法吗？
