brew 安装 node 及 npm用法

使用brew 安装node

首先先对 brew 进行检查

brew update
brew doctor

创建目录，并修改权限

因为权限问题，我这里是手动创建的。

sudo mkdir /usr/local/Cellar
sudo chown -R $(whoami) /usr/local/Cellar
	
sudo mkdir /usr/local/opt
sudo chown -R $(whoami) /usr/local/opt/
	
sudo mkdir /usr/local/opt/icu4c
sudo chown -R $(whoami) /usr/local/opt/
	
sudo mkdir /usr/local/include
sudo chown -R $(whoami) /usr/local/include/
	
sudo mkdir /usr/local/share
sudo chown -R $(whoami) /usr/local/share

然后进行安装

brew link node
brew uninstall node
brew install node

我这里失败了啊

brew uninstall --force node
brew uninstall icu4c && brew install icu4c
brew unlink icu4c && brew link icu4c --force
# 这里可能会提示设置 ~/.zshrc。 看底部 icu4c ~/.zshrc 这个模块
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc
# 如果执行了上面那条命令，需要更新资源文件
source ~/.zshrc

brew install node

icu4c ~/.zshrc

If you need to have icu4c first in your PATH run:

1
2


  echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.zshrc

For compilers to find icu4c you may need to set:

1

  export LDFLAGS="-L/usr/local/opt/icu4c/lib"
  export CPPFLAGS="-I/usr/local/opt/icu4c/include"

常用命令

npm install <module> //安装
npm uninstall <module> //卸载
npm search <module> //搜索
npm update <module> //更新

npm

npm 是node.js自带的功能。
