当尝试在react原生应用程序上运行jest时，测试会失败。找不到"setupDevtools“错误

Question

我正在尝试运行我的测试，但由于某些原因，我在执行npm run test时出现以下错误。

  ● Test suite failed to run

    Cannot find module 'setupDevtools' from 'setup.js'

      at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:229:17)
      at Object.<anonymous> (node_modules/react-native/jest/setup.js:9:6)

这是我的package.json

    "private": true,
    "name": "app",
    "version": "0.1.0",
    "scripts": {
    "start": "react-native start",

问题是我的依赖项上的版本不匹配。因为我使用了

"react": "16.3.1",
"react-native": "^0.55.4"

我不得不从"jest": "^24.7.1"降级到"jest": "23.6.0"。在那之后，babel出现了一些问题。已安装"@babel/core": "^7.4.5"和"@babel/runtime": "^7.4.5"。并最终完成安装"babel-jest": "^24.8.0", "@testing-library/jest-native": "^3.0.1" and "native-testing-library": "^3.1.1",的整个过程

带有react-native@0.55.4的最终package.json
