【问题描述】：

我是 react-native 的新手。我运行时不断收到此错误

react-native run-android

这是我的最后一个 package.json，上次我推送更改时它工作正常，但现在它似乎已经坏了。

我的 package.json

  "name": "taxiapp",
  "version": "0.0.1",
  "private": true,
  "scripts": 
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  ,
  "dependencies": 
    "@babel/runtime": "^7.0.0",
    "native-base": "^2.8.0",
    "react": "16.5.0",
    "react-addons-update": "^15.6.2",
    "react-native": "^0.54.1",
    "react-native-maps": "^0.21.0",
    "react-native-router-flux": "^4.0.5",
    "react-redux": "^5.0.7",
    "redux": "^4.0.0",
    "redux-thunk": "^2.3.0"
  ,
  "devDependencies": 
    "babel-jest": "23.6.0",
    "jest": "23.6.0",
    "metro-react-native-babel-preset": "^0.48.1",
    "react-test-renderer": "16.5.0",
    "redux-logger": "^3.0.6"
  ,
  "jest": 
    "preset": "react-native"
  

【参考方案1】：

尝试运行：

del %appdata%\Temp\react-* & del %appdata%\Temp\metro-* & del %appdata%\Temp\haste-* & watchman watch-del-all & npm start -- --reset-cache

如果仍然不起作用，您可以在这里尝试 2 个解决方案：

将 react-native 升级到 0.57.2

或降级 babel，据我所知，RN 0.54 使用 babel 6 而不是 7。

这是一个适用于 RN 0.57 的配置：

React native upgrade from babel 6 to babel 7

【讨论】：

谢谢！现在我得到这个新错误：错误：捆绑失败：错误：无法从C:\Users\Santiago\Google Drive\files\php\repos\taxiapp\node_modules\react-native\Libraries\Renderer\oss\ReactNativeRenderer-dev.js解析模块scheduler/tracing：模块scheduler/tracing在Haste模块映射中不存在

【参考方案2】：

请尝试将这些转换规则添加到您的 package.json 中：

"jest": 
  "preset": "react-native",
  "transform": 
    "^.+\\.js$": "<rootDir>/node_modules/react-native/jest/preprocessor.js"
  ,
  "transformIgnorePatterns": [
    "node_modules/(?!(jest-)?react-native)"
  ]
,
