How To Install Node.js on Ubuntu 20.04 | DigitalOcean
ubuntu20上默认用apt install 安装的nodejs版本是 v10.几
官方提供了对应的脚本， 下面的setup_19.x 如果你需要v18，就把19改成18.
# node 安装较新的版本
curl -sL https://deb.nodesource.com/setup_19.x -o /tmp/nodesource_setup.sh
sudo bash /tmp/nodesource_setup.sh
# The PPA will be added to your configuration and your local package cache will be updated automatically.
# You can now install the Node.js package in the same way you did in the previous section:
sudo apt install nodejs
node -v还有一种方法是使用node version manger, nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
source ~/.bashrc
nvm list-remote
