Question

So the crux of the problem, is I get the following error when running

rake -T

WARNING: Global access to Rake DSL methods is deprecated.  Please Include
    ...  Rake::DSL into classes and modules which use the Rake DSL methods.
WARNING: DSL method SeenicServer::Application#task called at /home/grantismo/.rvm/gems/ruby-1.9.2-p180/gems/railties-3.0.7/lib/rails/application.rb:215:in `initialize_tasks'
rake aborted!
no such file to load -- parse_tree

So obviously I did, gem install ParseTree.
Running gem list -d ParseTree produces:

*** LOCAL GEMS ***

ParseTree (3.0.7)
    Author: Ryan Davis
    Rubyforge: http://rubyforge.org/projects/parsetree
    Homepage: http://rubyforge.org/projects/parsetree/
    Installed at: /home/grantismo/.rvm/gems/ruby-1.9.2-p180

    ParseTree is a C extension (using RubyInline) that extracts the
    parse tree for an entire class or a specific method and returns it
    as a s-expression (aka sexp) using ruby's arrays, strings, symbols,
    and integers

it looks like I’m using the correct rake

which rake

/home/grantismo/.rvm/gems/ruby-1.9.2-p180/bin/rake

Most of the explanations I’ve read say to run sudo gem install ParseTree, but I don’t understand why I should be installing with sudo if I’m managing gems through rvm.

Any ideas? I’m a unix noob, so it might be something simple. Thanks for your time.

You need to make sure your Gemfile has a gem 'ParseTree' line in it, otherwise Rails won’t load it (even if the system has it installed).

After adding the line, do a bundle install.
