安装Node.js和npm、cnpm

我用的是MAC，没有用brew，个人觉得brew安装指定版本的软件比较烦

直接进Node官方网站下载，我下的.tar.gz

解压

tar -zxf node-v14.15.0-darwin-x64.tar.gz

设置环境变量

vi ./bash_profile

export NODE_HOME=/usr/local/node-v14.15.0-darwin-x64
export PATH=$PATH:$NODE_HOME/bin

#让配置生效
source ./bash_profile

验证

liuqideMacBook-Pro:local liuqi$ node -v
v14.15.0
liuqideMacBook-Pro:local liuqi$ npm -v
6.14.8

安装cnpm

npm install -g cnpm --registry=https://registry.npm.taobao.org

liuqideMacBook-Pro:local liuqi$ cnpm -v
