Reactjs 玩笑测试总是失败

我试图对我的React应用程序进行单元测试，当我运行npm run jest时，它失败了

Plugin/Preset files are not allowed to export objects, only functions. In /node_modules/babel-preset-react/lib/index.js

尝试了@babel/preset env和@babel/preset react的npm安装

请在package.json中找到我的笑话babel config

"jest": {
  "moduleNameMapper": {
    "^.+\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/test/jest/mocks/fileMock.js",

“开玩笑”：{
“moduleNameMapper”：{
“^.+\（jpg | jpeg | png | gif | eot | otf | webp | svg | ttf | woff | woff2 | mp4 | webm | wav | mp3 | m4a | aac | oga）$”：“/test/jest/mocks/fileMock.js，
“^.+\\（css | styl）$”：“身份对象代理”
},
“SetupFileAfterEnv”：[
“/test/jest/config.js”
],
“快照序列化程序”：[
“酶到json/序列化程序”
],
“设置文件”：[
“/test/jest/enzyme.js”
],
“testPathIgnorePatterns”：[
“/（节点单元）/”
]
},
“巴别塔”：{
“预设”：[
“@babel/preset env”，
“@babel/预设反应”
],
“插件”：[
“动态导入节点”
]
},
“依赖项”：{
“@babel/preset env”：“^7.3.1”，
@babel/preset react:“^7.0.0”
}

请建议启动并运行jest测试，并消除节点_模块中的错误
