個人工程建立時間是2019.7.11號下午：首先看一下最後個人工程的package.json各個包的版本：html

{
  "name": "MyApp",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.8.3",
    "react-native": "0.59.8",
    "react-native-gesture-handler": "^1.3.0",
    "react-navigation": "^3.11.0"
  },
  "devDependencies": {
    "@babel/core": "^7.5.4",
    "@babel/runtime": "^7.5.4",
    "babel-jest": "^24.8.0",
    "jest": "^24.8.0",
    "metro-react-native-babel-preset": "^0.55.0",
    "react-test-renderer": "16.8.3"
  },
  "jest": {
    "preset": "react-native"
  }
}

1.安裝依賴node

brew install node brew install watchman 注意 node>10
react

安裝yarn ios

npm install -g yarn react-native-cli
git

安裝完 yarn 後同理也要設置鏡像源：github

yarn config set registry https://registry.npm.taobao.org --global yarn config set disturl https://npm.taobao.org/dist --global

在Appstore下載Xcode  版本>10

React Native 目前須要Xcode 9.4 或更高版本。你能夠經過 App Store 或是到Apple 開發者官網上下載。

這一步驟會同時安裝 Xcode IDE、Xcode 的命令行工具和 iOS 模擬器。

建立新項目

安裝第三方依賴，再http://bbs.reactnative.cn/topic/4301/ios-rn-0-45以上版本所需的第三方編譯庫-boost等

選擇最高版本，複製到.rncahce文件夾下

須要安裝到根目錄下的.rncache文件夾因此執行一下操做，

hewenkedeMacBook-Pro:AwesomeProject hewenke$ cd ~npm

hewenkedeMacBook-Pro:~ hewenke$ mkdir .rncachejson

hewenkedeMacBook-Pro:~ hewenke$ cp ~/Downloads/boost_1_63_0.tar.gz ~/.rncache/ react-native

hewenkedeMacBook-Pro:~ hewenke$ cp ~/Downloads/double-conversion-1.1.5.tar.gz ~/.rncache/ xcode

hewenkedeMacBook-Pro:~ hewenke$ cp ~/Downloads/double-conversion-1.1.6.tar.gz ~/.rncache/

hewenkedeMacBook-Pro:~ hewenke$ cp ~/Downloads/folly-2018.10.22.00.tar.gz ~/.rncache/

hewenkedeMacBook-Pro:~ hewenke$ cp ~/Downloads/glog-0.3.5.tar.gz ~/.rncache/

hewenkedeMacBook-Pro:~ hewenke$ cd .rncache

hewenkedeMacBook-Pro:.rncache hewenke$ ls

boost_1_63_0.tar.gz folly-2018.10.22.00.tar.gz

double-conversion-1.1.5.tar.gz glog-0.3.5.tar.gz

double-conversion-1.1.6.tar.gz

hewenkedeMacBook-Pro:.rncache hewenke$ rm double-conversion-1.1.5.tar.gz

hewenkedeMacBook-Pro:.rncache hewenke$ ls

boost_1_63_0.tar.gz folly-2018.10.22.00.tar.gz

double-conversion-1.1.6.tar.gz glog-0.3.5.tar.gz

安裝完第三方依賴，就能夠建立新項目

react-native init AwesomeProject

初始化結束之後cd AwesomeProject && react-native run-ios

就能夠啓動項目

===>注意事項不要初始化0.44版本的項目。問題太多。
