clang: error: no such file or directory: 'CXX=c++'
解决办法：
For anything under v15, you will need to install node using Rosetta 2 You can do this by running the nvm installation commands inside the Rosetta 2 shell.
In Terminal
use arch -x86_64 zsh
to start a shell under Rosetta 2. Then you can run nvm install v12.
