问题

尝试在 React Navigation 中使用堆栈导航器时，我收到错误“无法读取未定义的属性‘状态’”。 Switch 和 bottomTabNavs 运行良好。

如果有人知道如何解决这个问题，那就太棒了！

我的尝试

我已经检查以确保 react-native-gesture-handler 已正确安装和链接。

我的 Package.json：

  "name": "app",
  "version": "5.1.0",
  "private": true,
  "devDependencies": 
    "babel-jest": "23.6.0",
    "fs-extra": "^6.0.1",
    "jest": "23.6.0",
    "metro-react-native-babel-preset": "0.49.2",
    "react-test-renderer": "16.7.0",
    "reactotron-react-native": "^3.2.0",
    "replace-in-file": "^3.4.2"
  ,
  "scripts": 
    "android": "react-native run-android",
    "ios": "react-native run-ios --simulator=\"iPhone X\"",
    "apk": "cd android && ./gradlew assembleRelease",
    "rename": "node ./bin/rename.js",
    "start": "react-native start",
    "test": "jest"
  ,
  "jest": 
    "preset": "react-native"
  ,
  "dependencies": 
    "axios": "^0.18.0",
    "lodash": "^4.17.11",
    "react": "16.6.3",
    "react-native": "0.58.0-rc.2",
    "react-native-firebase": "^5.2.0",
    "react-native-gesture-handler": "^1.1.0",
    "react-native-rate": "^1.1.6",
    "react-native-sensitive-info": "5.2.9",
    "react-native-splash-screen": "^3.2.0",
    "react-native-status-bar-height": "^2.3.1",
    "react-native-table-component": "^1.2.0",
    "react-navigation": "^3.3.2"
  

【参考方案1】：

问题在于，即使 react-native 链接表明包已成功链接，但 pod 文件并未安装。

要解决此问题，请按以下步骤操作：

cd ios Pod 安装 清理ios文件夹 运行应用程序
