react-native ios2020开发环境搭建

自学react-native,搭建ios环境踩了不少坑,仅供参考。。。

1.安装brew

/bin/zsh -c “$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)”

2.安装node

brew install node
npx nrm use taobao (可选切换淘宝源,快)

3.安装yarn (高级版npm)

npm install -g yarn

4.安装cocoapods (ios依赖库)

brew install cocoapods
切换源
pod repo remove trunk
pod repo add master https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git

5.安装watchman(官网文档说要装,但是我装了就会报错,卸载了就可以跑了,迷~)

·brew install watchman

6.安装xCode

appstore有

7.安装react-native-cli 脚手架

npm install -g react-native-cli

8.创建helloworld工程

react-native init helloworld

9.启动

cd helloworld;npm run ios

10.起飞
