when installing other software, the environment variable of NVM was accidentally deleted. After restoring the installation path of NVM in the system path, an error was reported using NVM
error open\ settings.txt : the system cannot find the file specified after comparing my environment variables with those of other people, I find that I am missing% NVM_ HOME%，%NVM_ Symlink% two variables add two paths to the path
add two variables to the system variables, and the variable values can be found in the NVM installation file settings.txt
