Question

In trying to use the mail gem from geany I get errors as so:

/home/thufir/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mail (LoadError)
    from /home/thufir/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from mail.rb:3:in `<main>'


------------------
(program exited with code: 1)
Press return to continue

However, the program runs fine from the CLI:

thufir@dur:~$ 
thufir@dur:~$ ruby ruby/mail.rb 
hello world
hello world
thufir@dur:~$ 
thufir@dur:~$ nl ruby/mail.rb 
     1  require 'yaml'
     2  require 'net/imap'
     3  require 'mail'

     4  2.times do
     5    puts 'hello world'
     6  end
thufir@dur:~$ 
thufir@dur:~$ ruby -v

thufir@dur:~$ 

Why does geany have trouble with the mail gem?

Just to confirm:

thufir@dur:~$ 
thufir@dur:~$ type rvm | head -1
rvm is a function
thufir@dur:~$ 
thufir@dur:~$ gem list --local

Answer 1

your system is not configured to use login shell, here is an example how to enable login shell in gnome terminal https://rvm.io/integration/gnome-terminal/

also running:

rvm get head --auto-dotfiles

will update your shell configuration to load rvm in the “right” way
