Question

我们办公室里有一个小小的hackaton，我在react-native-maps时遇到了一些问题。我收到错误： undefined不是一个对象（评估＆＃39; PropTypes.string＆＃39;），它将从MapView转到MapMaker.js文件。

有我的package.json文件：

{
  "name": "niehandlowa",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "rnpm": {
    "assets": [
      "./assets/fonts/"
    ]
  },
  "dependencies": {
    "native-base": "^2.3.10",
    "prop-types": "^15.6.1",
    "react": "16.3.0-alpha.3",
    "react-native": "^0.54.2",
    "react-native-elements": "^0.19.0",
    "react-native-maps": "^0.4.2",
    "react-native-router-flux": "^4.0.0-beta.30",
    "react-redux": "^5.0.7",
    "redux": "^3.7.2",
    "redux-thunk": "^2.2.0"
  },
  "devDependencies": {
    "babel-jest": "22.4.3",
    "babel-preset-react-native": "4.0.0",
    "jest": "22.4.3",
    "react-test-renderer": "16.3.0-alpha.3"
  },
  "jest": {
    "preset": "react-native"
  }
}

我很高兴，因为今天我们的团队希望完成我们昨天开始的优秀应用程序：）

每个人都过得愉快！

Answer 1

很可能与您使用的PropTypes版本有关。 v0.4.2正在使用react和library separated now中的DELETE FROM users WHERE id in ( SELECT id FROM users ORDER BY id desc LIMIT 3 )。您应该使用更新版本的react-native-maps library

react-native-maps undefined不是一个对象（评估＆＃39; PropTypes.string＆＃39;）
