NVM installation under Deepin [npm + node]

System environment: deepin (Ubuntu 18.04 is also applicable)

1. 
   sudo apt update && apt upgrade -y
   During the system update, select yes for all prompts, and restart the system after the end (based on the system just installed)
   sudo reboot
2. Install git.
   sudo apt install git -y
   If there is one in the system, there is no need to install it, generally there is no? I heard that it is generally available, but I have not used it. . .
3. Install wget
   sudo apt install wget -y
4. If you encounter a prompt about insufficient permissions to install nvm , add sudo
   nvm before the command to
   create the directory
   mkdir -p /usr/local/nvm
   for nodejs and npm . Download the source code.
   git clone https://github.com/nvm-sh/nvm.git /usr/local/nvm
   Switch the directory.
   cd /usr/local/nvm
   Install.
   ./install.sh
   Add Taobao mirror.
   export NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/dist
   Restart the configuration file. You can restart Linux to
   source ~/.bash #输入到这的时候按两下Tab键看看到底是哪一个 我用的deepin是.bashrz | Ubuntu应该是bash_profile
   start the installation.
   nvm install stable
5. verification
   node -v
