react-native错误：模块映射中不存在模块

Question

这是错误：

我已经尝试了Github问题中的所有内容，错误描述和此问题，但均无济于事。

这是我的package.json：

{
  "name": "MyAppName",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "jest-expo": "^24.0.0",
    "react-native-scripts": "1.8.1",
    "react-test-renderer": "16.2.0"
  },
  "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js",
  "scripts": {
    "start": "react-native-scripts start",
    "eject": "react-native-scripts eject",
    "android": "react-native-scripts android",
    "ios": "react-native-scripts ios",
    "test": "node node_modules/jest/bin/jest.js --watch"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "core-js": "^2.5.3",
    "expo": "^24.0.2",
    "react": "^16.2.0",
    "react-native": "^0.51.0",
    "react-native-awesome-alerts": "^1.0.3",
    "react-native-barcode-builder": "^1.0.2",
    "react-native-communications": "^2.2.1",
    "react-native-hyperlink": "^0.0.11",
    "react-native-image-pan-zoom": "^2.0.16",
    "react-native-image-zoom-viewer": "^2.0.18",
    "react-native-open-maps": "^0.1.1",
    "react-native-swiper": "^1.5.13",
    "react-native-vector-icons": "^4.4.2",
    "react-navigation": "^1.0.0-beta.22",
    "rn-viewpager": "^1.2.9"
  }
}

对于任何未来的查看者：这是一个依赖性问题。如果使用版本控制，请将旧的依赖项复制到当前版本中package.json

Answer 1

这是一个依赖性问题。如果您使用版本控制，请将旧的依赖项复制到当前的依赖项中package.json

我无法弄清楚出了什么问题，所以我只是从 GitHub 重新克隆了我的项目并复制了我的代码。
