npm 找不到某些 react-native 模块的依赖项

Question

我正在使用 create-react-native-app 创建一个 React Native 应用

npm create-react-native-app 

我更新了react-native版本到0.44.0，这需要更新react版本到16.0.0-alpha.6这是我的 package.json

{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-native-scripts": "0.0.29",
    "jest-expo": "^0.4.0",
    "react-test-renderer": "~15.5.4"
  },
  "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": {
    "@expo/ex-navigation": "^2.11.1",
    "babel-preset-react-native-stage-0": "^1.0.1",
    "expo": "^16.0.0",
    "react": "~16.0.0-alpha.6",
    "react-native": "0.44.0"
  }
}

运行 npm install 会出现以下错误

C:\dev\repo\test>npm install
npm WARN lottie-react-native@1.1.1 requires a peer of react@>=15.3.1 but none was installed.
npm WARN react-native-maps@0.12.2 requires a peer of react@>=15.4.0 but none was installed.
npm WARN react-native-svg@4.4.1 requires a peer of react@>=15.4.0 but none was installed.
npm WARN react-static-container@1.0.1 requires a peer of react@^0.13.0 || ^0.14.0 || ^15.0.0 but none was installed.

看起来 react 版本 16.0.0-alpha.6 无法被 lottie-react-native、react-native-maps、react-native-svg 和 react-static-container 识别。我不确定是否必须满足主要版本 (15)，或者这些库未使用 alpha 版本 16，或者其他。有谁知道如何解决这一问题？谢谢。

我有一个类似的问题，实际上现在我遇到了这个问题，每当我尝试使用 create-react-native-app 创建一个新的应用程序时。我现在找到的唯一解决方案 (hack) 是:

1. 删除 node_modules(对我来说，仅仅执行 npm install 是不够的)
2. 执行npm install
