Javascript 开玩笑地使用es7装饰器

我在我的项目中使用了装饰器，但似乎巴贝尔笑话不支持这个新的实验特性 我从这个==>中找到了一些支持，它将babel jest替换为Web包babel jest，并修复了装饰器问题。但是，当我运行npm run test==>“ReferenceError:regeneratorRuntime未定义”时，出现了一个新问题 看来我们需要再生器运行时。（我在我的项目中使用了redux saga）我找不到解决这个问题的方法

package.json {
"babel-core": "^6.7.6",
"babel-eslint": "^7.2.3",
"babel-jest": "^21.2.0",
"babel-loader": "^6.2.4",

我找不到办法解决这个问题

这是众所周知的regenerator transform babel插件问题，它通常用于用sagas传输代码

请参阅此处的详细解释：

最好从“再生器运行时”显式地导入*在每个测试失败的文件中

   .babelrc {
{
"presets": [
    "es2015",
    "react",
    "stage-0"
],
"plugins": [
    "transform-decorators-legacy",
    "transform-react-jsx-source",
    "transform-class-properties",
["transform-runtime", {
  "polyfill": false,
  "regenerator": true
    }
],
"env": {
    "development": {

        "presets": [
            "react-hmre"
        ]
    },
    "test": {
        "presets": [
            "es2015",
            "react",
            "stage-0"
        ]
    }
}
}
}
