1.下载安装包
wget https://nodejs.org/dist/v14.15.4/node-v14.15.4-linux-x64.tar.xz
2.解压并放入制定目录
tar -xf node-v14.15.4-linux-x64.tar.xz
mv node-v14.15.4-linux-x64 /usr/local/node
3.建立软链接
cd /usr/bin
ln -s /usr/local/node/bin/node node
ln -s /usr/local/node/bin/npm npm
4,配置淘宝镜像
npm config set registry https://registry.npm.taobao.org
5.查看是否切换成功
npm config get registry
如果npm不好使,使用cnpm
npm install -g cnpm --registry=https://registry.npm.taobao.org
cd /usr/bin
ln -s /usr/local/node/bin/cnpm cnpm
