I need help getting Textmate to find gems. I've spent quite a bit of type researching the problem, but being new to both OS X (Snow Leopard) and the use of Ruby gems, I can't seem to figure out what the problems are. Many others have had similar problems, but their solutions don't seem to fix my problems. (Among other things, I did read Section 8--Shell Commands--of the Textmate manual.) I expect it largely has to do with the setting of environmental variables, but that's just a guess. A secondary--and no doubt related--problem is that Ruby cannot find the gem active-record when invoked in a terminal (or in irb), as shown below.

I've tried entering a TM_PATH shell variable in Textmate preferences, but that hasn't helped.

Here are some possible clues. No doubt I have provided some unnecessary information and have left out important information.

I recently used RVM (Ruby Version Manager) to reinstall Ruby. From a terminal I then ran gem install xml-simple gem install sqlite3 gem install activerecord They all appeared to install OK.

Then I wrote the following short script (test.rb): ************ #!/usr/local/bin/ruby # Ruby 1.9.2

require 'rubygems' print 'Gem.path = ' puts Gem.path print 'ruby_description = ' puts RUBY_DESCRIPTION

require 'xmlsimple' require 'sqlite3' require 'active-record' *************

When I run test.rb in a terminal I get: ************* MacBook-Pro-2:economics101 cary$ ruby test.rb Gem.path = /Users/cary/.rvm/gems/ruby-1.9.2-p0 /Users/cary/.rvm/gems/ruby-1.9.2-p0@global ruby_description = ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0] internal:lib/rubygems/custom_require:29:in `require': no such file to load -- activerecord (LoadError) from internal:lib/rubygems/custom_require:29:in `require' from test.rb:12:in `<main>' *************

When I run Ruby test.rb from within Textmate (cntrl-r), I get: ************* Gem.path = /Users/cary/.rvm/gems/ruby-1.9.2-p0@global /usr/local/lib/ruby/gems/1.9.1 ruby_description = ruby 1.9.2dev (2010-07-02 revision 28524) [x86_64-darwin10.4.0] LoadError: no such file to load — sqlite3

method require in test.rb at line 11 method <main> in test.rb at line 11 copy output ************* (If I have <require 'active-record'> before <require 'sqlite3'>, I get the same message, with 'active-record' substituted for 'sqlite3'.)

Notice that xmlsimple was found when running test.rb from a terminal, but not with cntrl-r in Textmate. See below (near the end) where I think Textmate found xmlsimple.

Next I ran irb: ************* MacBook-Pro-2:~ cary$ irb /Users/cary/.rvm/rubies/ruby-1.9.2-p0/bin/irb:4: warning: Insecure world writable dir /Users/cary in PATH, mode 040777

ruby-1.9.2-p0 > RUBY_DESCRIPTION => "ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]"

ruby-1.9.2-p0 > Gem.path => ["/Users/cary/.rvm/gems/ruby-1.9.2-p0", "/Users/cary/.rvm/gems/ruby-1.9.2-p0@global"]

ruby-1.9.2-p0 > require 'xmlsimple' => true

ruby-1.9.2-p0 > require 'sqlite3' => true

ruby-1.9.2-p0 > require 'active-record' LoadError: no such file to load -- active-record from internal:lib/rubygems/custom_require:29:in `require' from internal:lib/rubygems/custom_require:29:in `require' from (irb):1 from /Users/cary/.rvm/rubies/ruby-1.9.2-p0/bin/irb:17:in `<main>'

(ibr's message, "warning: Insecure world writable dir /Users/cary in PATH, mode 040777" is something I should look into as well.) *************

(It makes no difference if I precede the above with <'require rubygems'>.)

and then back at a terminal: ************* MacBook-Pro-2:~ cary$ ruby -v ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]

MacBook-Pro-2:~ cary$ which ruby /Users/cary/.rvm/rubies/ruby-1.9.2-p0/bin/ruby

MacBook-Pro-2:~ cary$ echo $PATH /Users/cary/.rvm/gems/ruby-1.9.2-p0/bin: /Users/cary/.rvm/gems/ruby-1.9.2-p0@global/bin: /Users/cary/.rvm/rubies/ruby-1.9.2-p0/bin: /Users/cary/.rvm/bin:/usr/local/bin: /usr/local/sbin: /usr/local/mysql/bin: /usr/bin:/bin: /usr/sbin: /sbin: /usr/local/bin: /usr/X11/bin

MacBook-Pro-2:economics101 cary$ ls /Users/cary/.rvm/gems/ruby-1.9.2-p0@global/gems MacBook-Pro-2:economics101 cary$

MacBook-Pro-2:economics101 cary$ ls /usr/local/lib/ruby/gems/1.9.1/gems libxml-ruby-1.1.4 xml-simple-1.0.12 ************* The last line suggests to me that, from Textmate, Ruby is using an old version of xlm-simple.

Any help would be greatly appreciated.
