Question

我在我的项目中使用装饰器，但似乎巴贝尔开玩笑不支持这个新的实验功能我从github issue ===＆gt;中找到了一些支持。用webpack-babel-jest取代babel-jest，它解决了装饰问题。但是当我运行npm run test ==＆gt;时出现了一个新问题。＆＃34; ReferenceError：未定义regeneratorRuntime＆＃34; 看来我们需要再生器 - 运行时。（我在我的项目中使用redux-saga）我无法找到解决这个问题的方法。

我无法解决这个问题。

这是众所周知的再生器变换babel插件的问题，它通常用于传输带有传奇的代码。
