react-native - 如何修复 'undefined is not an object (evaluating ' NativeModules ["SQLite"][方法 ]')'

Question

我无法在我的应用程序中使用“react-native-sqlite-storage”。我正在使用 expo 构建纯 react-native 应用程序。

我已经尝试重新安装 React Native，但没有成功。

这是我的 package.json-

"main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {
    "@expo/vector-icons": "^10.0.1",
    "axios": "^0.18.0",
    "expo": "^32.0.0",
    "native-base": "^2.12.1",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
    "react-native-camera": "^2.10.0",
    "react-native-camera-kit": "^8.0.0",
    "react-native-easy-grid": "^0.2.1",
    "react-native-sqlite-storage": "^3.3.10",
    "react-navigation": "^3.11.0",
    "realm": "^2.28.1"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0"
  },
  "private": true
}

库没有链接到它的本地代码。 如果您使用的是 Expo，则可以使用 SQLite Api

如果您想使用react-native-sqlite-storage，您必须弹出您的应用程序并链接库，如图所示here
