Libraries missing for ruby 2.3.1 - ruby

Question

currently trying to install Ruby 2.3.1 using rvm on my terminal(macOS Sierra) but ran into this error
Libraries missing for ruby-2.3.1:
/Users/travis/.rvm/rubies/ruby-2.3.1/lib/libruby.2.3.0.dylib,/usr/local/opt/gdbm/lib/libgdbm.4.dylib. Refer to your system manual for installing libraries
This error is similar to another question on stack overflow but the solution there did not work for me.
I am new to Ruby, so any help would be much appreciated.
This is the full output from the terminal by the way.

I have the same error but the installation completes successfully.

But your message looks quite explicit:
/bin/sh: /Applications/Xcode-beta: No such file or directory
Do you have that directory?

Answer 2

First of all, do you have Xcode installed? If not, you can just get the command line tools here: http://railsapps.github.io/xcode-command-line-tools.html
It seems like the message is saying that you had Xcode-beta but removed it and now it has no way to install properly. The command line tools should be good enough
