Question

mac终端安装node时候，显示“-bash: brew: command not found”，怎么解决？

Answer 1

先安装brew

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

Answer 2

没安装 Homebrew

bash 下执行 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Answer 3

如果出现 brew not found :

sudo find / -name brew # 查看是否存在 brew, 如果不存在就删除下述两个文件
rm -rf /usr/local/Cellar
rm -rf /usr/local/.git

然后重新安装 brew 就 ok 了

Answer 4

删了以后，终端连ls,ll,....这些命令都不能用了；
