Question

我花了整整一天的时间尝试使地图视图正常工作，并一路走来，发现了这个错误，我在互联网上找不到任何地方。错误代码在iOS模拟器上显示为红色，这是React native的典型现象。

我尝试重新安装开发工具，但没有成功。

这是我的package.json

{
  "name":"P77",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "^16.7.0",
    "react-native": "0.57.8",
    "react-native-elements": "^0.19.1",
    "react-native-maps": "^0.22.1",
    "react-native-vector-icons": "^6.1.0",
    "react-navigation": "git+https://github.com/react-community/react-navigation.git"
  },
  "devDependencies": {
    "babel-jest": "23.6.0",
    "jest": "23.6.0",
    "metro-react-native-babel-preset": "0.51.1",
    "react-devtools": "^3.4.3",
    "react-test-renderer": "16.6.3"
  },
  "jest": {
    "preset": "react-native"
  }
}

请帮助

我找到了一个对我有用的答案，但我不确定。也许这可以在将来对人们有所帮助。我跑了：

"yarn add eslint-config-rallycoding --dev" 
"npm start"

（在项目目录中）

未定义不是函数（在'... reactDevTools.connectToDevTools ...'附近）
