按照中文網(wǎng)一步一步往下：
1.先安裝這個(gè)brew 先较，打開網(wǎng)址：https://brew.sh里頭有安裝指令：
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
安裝完brew血崭，就可以安裝node ，watchman,yarn,cocoapods
如果安裝brew報(bào)錯(cuò)：
Failed to connect to raw.githubusercontent.com port 443: Connection refused
打開此網(wǎng)站（https://githubusercontent.com.ipaddress.com/raw.githubusercontent.com
）查看raw.githubusercontent.com 的ip地址，然后修改 /etc/hosts 文件，新增：
# 你查到的IP地址
199.232.68.133 githubusercontent.com
brew install node
brew install watchman
# 使用nrm工具切換淘寶源
npx nrm use taobao
npm install -g yarn
brew install cocoapods
最后就是：
cd AwesomeProject
yarn ios
# 或者
yarn react-native run-ios
會有一個(gè)報(bào)錯(cuò)：
error Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.
Please try again manually: "cd ./iosProject/ios && pod install".
這個(gè)沒事届榄，按照提示：
#先設(shè)置xcode路徑
sudo xcode-select --switch /Applications/Xcode.app
cd ./iosProject/ios && pod install
