Re: Installing ruby with RVM cannot find <CoreFoundation/CFString.h>

Hello Nicholas Gallimore,

Seams like you installed ruby with HomeBrew. It's not multiple ruby version. Its Inheritance. Every time you update there will be old code of old ruby version inside it. So Don’t very about it. 

Yes you are getting error inside rails because you are not using correct ruby with correct rails version. 

I am more of a RVM user, So I can suggest to use RVM for managing ruby by simple commands:

$ rvm install ruby-2.6.2 --default
$ rvm gemset create name_of_project
$ gem gemset use name_of_project
$ gem install bundler
$ gem install rails
$ 

You can also manage ruby versions form rvmrc file

So that you need not to switch ruby version every time, but latest rvm switch between automatic hence, you can use ramrc file in a much better way.

Always install bundler first then rails for version stability.

I hope your problem get solved by this.

Thank You,

I have been trying to install ruby using rvm for a week now and I have had little success. Both rvm and rbenv complain about not being able to find CoreFoundation/CFString.h on OSX. I know this is more of a question related specifically to my machine, but how can I fix my machine? I have posted on Apple forums, stackoverflow 3-4 times, etc., not sure where else to go from here.
