Ruby installation issues with RVM

Question

I've been following the directions at http://installrails.com to get my Macbook Air setup for some ruby work but I am running in any issue with RVM. When I try to install Ruby I get the following errors. I also see them when trying to run ruby -v.

dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib
  Referenced from: /Users/Chris/.rvm/rubies/ruby-2.1.3/bin/ruby
  Reason: image not found

Googling around hasn't solved it, so I am confused what is causing it. Any suggestions?

Solution 1

I had the exact same problem when setting up RVM on my new Mac this morning:

$ ruby -v
dyld: Library not loaded: /usr/local/lib/libgmp.10.dylib
Referenced from: /Users/psoshnin/.rvm/rubies/ruby-2.1.3/bin/ruby
Reason: image not found

To solve the issue I first ran:

$ brew update && brew upgrade

Then I ran:

$ rvm reinstall 2.1.3 --disable-binary

And it installed successfully for me.

$ ruby -v
ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-darwin13.0]

Hope this helps.

Solution 2

This worked for me:

brew update && brew install gmp && rvm reinstall 2.1.3

Oh you are a champion! :D Now if only it made sense why it was being silly...

I didn't want to upgrade my various packages for this single issue, so I just ran: brew update && brew install gmp && rvm reinstall 2.1.3

I didn't have gmp installed. So the comment from @LeeXGreen worked best for me: brew update && brew install gmp && rvm reinstall 2.1.3
