React Native 环境搭建

1，安装 HomeBrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2, 安装 nvm

brew install nvm

安装以后可能会提示

按照上面的提示，终端执行以下代码：

mkdir ~/.nvm

vi ~/.zshrc

进入 ~/.zshrc  以后执行在末尾插入

export NVM_DIR="$HOME/.nvm"
  . "/usr/local/opt/nvm/nvm.sh"

3，安装 node.js

nvm install node && nvm alias default node 

4, 安装 watchman

brew install watchman

brew install flow

如果之前通过 brew安装 node, 卸载 node

brew remove --force node
sudo rm -r /usr/local/lib/node_modules
 
brew prune
sudo rm -r /usr/local/include/node
 
# 检查brew是否正常
brew doctor
