                                        RN学习之路1：mac系统下搭建RN环境

1，安装homebrew 

         终端输入 ruby -e "$(curl --insecure -fsSL         https://raw.githubusercontent.com/Homebrew/install/master/install)"

        如果遇到报错：curl: (7) Failed to connect to raw.githubusercontent.com port 443 after 13 ms: Connection refused

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

2，安装RN的依赖

    brew install node

    brew install watchman 

    //需要依赖python报错：Error: python@3.10: the bottle needs the Apple Command Line Tools to be installed.

    解决：官网下载安装：

（1）下载python的地址：https://www.python.org/downloads/

（2）安装完毕后终端输入python3，如下图所示即安装成功

    brew install flow

3，安装React Native

    npm install -g react-native-cli

4，创建RN项目

    react-native init HelloRN

报错 Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.

Please try again manually: "cd ./HelloRN/ios && pod install".

解决：按照提示操作即可

有可能需要更新cocoapods版本

sudo gem install cocoapods
