标题已经很清楚地解释了我所面临的问题。我正在尝试测试一个具有一些状态的React组件，并尝试为该组件提供我的存储以获取它所需的内容。当我使用Jest运行组件测试时，我会收到以下错误：
ReferenceError: regeneratorRuntime is not defined
通过一些阅读，我已经确定这是由于babel-polyfill或regenerator-runtime未正确应用于Jest引起的。然而，我已经尝试安装这两个包并重新运行测试，但结果没有变化。在阅读Jest Github问题页面（Remove auto-inclusion of babel-polyfill #2755）之后，我发现自2019年版本19以来，Jest不再自动包括babel-polyfill。我手动安装该软件包应该可以解决问题，但事实并非如此。我已经包含了一些我认为相关的文件。

import "babel-polyfill"，并在我的.babelrc的plugins部分提供它，但没有任何变化。 - rafafan2010
