What do

ruby -v

and

which ruby

show (is 'which ruby' the right command on OSX for findinq which
executable is being called when you run ruby? If not then run
whatever command will tell you that).

Is it correct to have a config like this?

RubyGems Environment:
- RUBYGEMS VERSION: 2.0.14
- RUBY VERSION: 2.0.0 (2015-04-13 patchlevel 645)
[universal.x86_64-darwin15]
- INSTALLATION DIRECTORY:
/Users/myname/.rvm/gems/ruby-1.9.3-p327@global
- RUBY EXECUTABLE:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby
- EXECUTABLE DIRECTORY:
/Users/myname/.rvm/gems/ruby-1.9.3-p327@global/bin
- RUBYGEMS PLATFORMS:
- ruby
- universal-darwin-15
- GEM PATHS:
- /Users/myname/.rvm/gems/ruby-1.9.3-p327@global
- GEM CONFIGURATION:
- :update_sources => true
- :verbose => true
- :backtrace => false
- :bulk_threshold => 1000
- REMOTE SOURCES:
- https://rubygems.org/

I notice Ruby 2 and Ruby 1.9 mentioned and I'm a little bit confused

Thanks.

Hi Colin

ruby -v

which ruby
/usr/bin/ruby

You are using the wrong ruby. Since you are using rvm you should be
using the one from the .rvm directory. You have probably done
something like compiling the gems with 1.9.3 but running them with
2.0.0.

That means something is wrong with your rvm setup. Did you install it
using the instructions at
https://rvm.io/

Also what does
rvm info
show?

Uhm ... I've got this.

Warning! PATH is not properly set up,
'/Users/myname/.rvm/gems/ruby-1.9.3-p327@global/bin' is not at first
place,
usually this is caused by shell initialization files - check
them for 'PATH=...' entries,
it might also help to re-add RVM to your dotfiles: 'rvm get
stable --auto-dotfiles',
to fix temporarily in this shell session run: 'rvm use
ruby-1.9.3-p327@global'.

I've to say that the problem now not occurs and I didn't do nothing to
fix it.
It seems randomic

[Colin Law]

The message says that your path is not correctly setup, so it may pick
up the wrong ruby.
'which ruby' should show the one in .rvm, if it doesn't you will get
problems. I don't know about Macs so don't know how you should fix
it.

Ok, thanks for your support.

[Yuri Redaelli]

In order to fix what showed during RVM INFO I needed to move this line

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" #
Load RVM into a shell session *as a function*

at the bottom of my bash_profile

Ah yes, that would explain it, if that was not in the right place.
Glad you got it fixed.

Cheers
