Question

我有一个react-native项目，带有以下package.json文件：

{
  "name": "react-native-paper-example",
  "version": "0.0.1",
  "description": "Example for React Native Paper",
  "author": "",
  "private": true,
  "scripts": {
    "flow": "flow",
    "start": "expo start",
    "android": "expo android",
    "ios": "expo ios"
  },
  "main": "node_modules/expo/AppEntry.js",
  "dependencies": {
    "@expo/vector-icons": "^9.0.0",
    "create-react-context": "^0.2.3",
    "expo": "^32.0.0",
    "expo-core": "^2.0.0",
    "expo-font": "^2.0.0",
    "query-string": "^6.2.0",
    "react": "16.7.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
    "react-native-paper": "^2.4.0",
    "react-native-svg": "^9.0.5",
    "react-navigation": "^3.0.9"
  },
  "devDependencies": {
    "babel-plugin-module-resolver": "^3.1.1",
    "babel-preset-expo": "^5.0.0",
    "expo-cli": "^2.3.8",
    "flow-bin": "^0.91.0"
  },
  "resolutions": {
    "**/create-react-context": "0.2.3",
    "**/hoist-non-react-statics": "2.5.0",
    "**/react-lifecycles-compat": "3.0.4",
    "**/react": "16.5.0"
  }
}

要安装我运行的模块：

$ yarn install

我的问题是我跑步时出现的问题：

$ expo start

我收到以下错误：

关于如何解决此问题的任何想法？

谢谢！

您可能应该从分辨率中删除此行"**/react": "16.5.0"，因为它与您指定为依赖项的React版本不兼容："react": "16.7.0",

重复的模块名称：react
