标题几乎可以解释我所面临的问题。我正在尝试测试React具有某种状态的组件，并且试图为该组件提供存储以获取所需的组件。当我使用Jest运行组件的测试时，出现以下错误：

ReferenceError: regeneratorRuntime is not defined

我已经通过了一些读数确定，这是造成babel-polyfill或者regenerator-

runtime没有被正确适用于玩笑。但是，我尝试安装这两个软件包并重新运行，但结果没有变化。阅读Jest Github问题页面（删除babel-

polyfill的自动包含＃2755）后，我发现babel-

polyfillJest从版本19开始不自动包含它。我手动安装该软件包应该已解决了问题，但确实如此不。我包括了一些我认为相关的文件

.babelrc：

{
  "presets": ["es2015", "react", "stage-2"],
  "env": {
    "development": {
      "plugins": [
        ["react-transform", {
          "transforms": [{
            "transform": "react-transform-hmr",
            "imports": ["react"],
            "locals": ["module"]
          }]
        }]
      ]
    }
  }
}

jest.config：

{
    "transform": {
        "^.+\\.(js|jsx)$": "<rootDir>/node_modules/webpack-babel-jest",
        ".*\\.(vue)$": "<rootDir>/node_modules/jest-vue-preprocessor",
        ".*": "babel-jest"
    },
    "moduleNameMapper": {
        "\\.(jpg|jpeg|css|scss|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/__tests__/__mocks__/fileMock.js",
        ".*\\.(vue)$": "vue/dist/vue.js"
    },
    "testPathIgnorePatterns": ["type_parser.spec.js", 
                               "<rootDir>/__tests__/__mocks__/",
                               "__tests__/unit/core/util/type_parser.js",
                               "__tests__/GitlabLoader.test.js"
                               ]
}
