I have tried the standard
brew uninstall node
and even went to /usr/local/ to delete the files according to this post: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)
I have received a bunch of error messages but when I type
node -v
I still get v8.9.4. I can't seem to uninstall it. I'm trying to get to version v6.10.0. Now when I type brew uninstall node it gives the error
Error: No such keg: /usr/local/Cellar/node
What more do I need to do?
