1. Download the installation package and unzip it
这里的/user/local/node 是我自己建立的文件夹
# cd /user/local/node
# wget https://nodejs.org/dist/v14.16.0/node-v14.16.0-linux-x64.tar.xz && xz -d node-v14.16.0-linux-x64.tar.xz && tar -xvf node-v14.16.0-linux-x64.tar
2. Configure soft connections
ln -s /usr/local/node/node-v4.4.7-linux-x64/bin/npm /usr/local/bin/npm
ln -s /usr/local/node/node-v4.4.7-linux-x64/bin/node /usr/local/bin/node
