Step 5: Modify the nvm configuration file (optional)

After the nvm installation is complete, open the settings.txt file in the nvm installation directory:

root: D:\nvm
path: D:\nvm\nodejs 
arch: 64 
proxy: none
node_mirror: http://npm.taobao.org/mirrors/node/
npm_mirror: https://npm.taobao.org/mirrors/npm/

Root and path are the installation paths of nvm and node respectively. Do not touch these two. They are automatically generated according to the path you selected during the previous installation. This configuration file only has these two items by default. Because I didn’t change the configuration file, I didn’t have the following 4 items. I just found it later. Let’s talk about it. Arch indicates how many nodes are installed, proxy is to set the proxy, and node_mirror is to change the mirror when nvm downloads node. Here It is set to Taobao mirror, and npm_mirror is to change the mirror of npm download dependent packages, and it is also modified to Taobao mirror.

Step 6: Install node

Check the version of node that nvm supports to install.
Use nvm list available
