用户配置不覆盖默认配置

[happylindz]

{
  "presets": [["env", { "modules": false }], "react"],
  "plugins": [
    "babel-plugin-transform-decorators-legacy",
    "transform-object-rest-spread",
    "transform-class-properties",
    ["import-fix", {
      "libraryName": "antd",
      "libraryPath": "antd/lib/${name}/index.js",
      "namePolicy": "dash",
      "cssPath": ""
    }]
  ]
}

我将 cssPath 置空，但是还是会按照默认配置进行读取，我看之前有人提了 issue，但还是存在这个问题？
