In MAC OS Catalina,
this are the steps that worked for me, all the above solutions did help but didn't solve my problem.
- check node --version, still the old one in use.
- cd ~/
- atom .bash_profile
- Remove the $PATH pointing to old node
version, in my case it was /usr/local/bin/node/@node8
- Add & save this to $PATH instead "export
PATH=$PATH:/usr/local/git/bin:/usr/local/bin"
- Close all applications using node (terminal, simulator, browser expo etc)
- restart terminal and check node --version
