I''m learning to use activerecord (not rails). Two gems are necessary for this: the activerecord gem and the mysql adpater (I''m using MySQL). I installed both gems (I think successfully). When I inspect the directory where all my local gems are installed, I get this: ~/.rvm/gems/ruby-1.9.2-p290/gems marcc$ ls total 0 drwxr-xr-x 28 marcc staff 952B Aug 15 19:47 . drwxr-xr-x 7 marcc staff 238B Jul 25 11:58 .. drwxr-xr-x 8 marcc staff 272B Jul 25 12:07 abstract-1.0.0 drwxr-xr-x 6 marcc staff 204B Jul 25 12:07 actionmailer-3.0.9 drwxr-xr-x 6 marcc staff 204B Jul 25 12:07 actionpack-3.0.9 drwxr-xr-x 6 marcc staff 204B Jul 25 12:07 activemodel-3.0.9 drwxr-xr-x 6 marcc staff 204B Jul 25 12:07 activerecord-3.0.9 drwxr-xr-x 6 marcc staff 204B Jul 25 12:07 activeresource-3.0.9 drwxr-xr-x 5 marcc staff 170B Jul 25 12:07 activesupport-3.0.9 drwxr-xr-x 12 marcc staff 408B Jul 25 12:07 arel-2.0.10 drwxr-xr-x 9 marcc staff 306B Jul 25 12:07 builder-2.1.2 drwxr-xr-x 14 marcc staff 476B Jul 25 12:08 bundler-1.0.15 drwxr-xr-x 14 marcc staff 476B Jul 25 12:07 erubis-2.6.6 drwxr-xr-x 8 marcc staff 272B Jul 25 12:07 i18n-0.5.0 drwxr-xr-x 7 marcc staff 238B Jul 25 12:07 mail-2.2.19 drwxr-xr-x 12 marcc staff 408B Jul 25 12:07 mime-types-1.16 drwxr-xr-x 13 marcc staff 442B Aug 15 19:47 mysql-2.8.1 drwxr-xr-x 9 marcc staff 306B Jul 25 12:07 polyglot-0.3.1 drwxr-xr-x 13 marcc staff 442B Jul 25 12:07 rack-1.2.3 drwxr-xr-x 5 marcc staff 170B Jul 25 12:07 rack-mount-0.6.14 drwxr-xr-x 14 marcc staff 476B Jul 25 12:07 rack-test-0.5.7 drwxr-xr-x 3 marcc staff 102B Jul 25 12:08 rails-3.0.9 drwxr-xr-x 6 marcc staff 204B Jul 25 12:08 railties-3.0.9 drwxr-xr-x 12 marcc staff 408B Jul 25 11:58 rake-0.8.7 drwxr-xr-x 14 marcc staff 476B Jul 25 12:08 rdoc-3.8 drwxr-xr-x 9 marcc staff 306B Jul 25 12:07 thor-0.14.6 drwxr-xr-x 11 marcc staff 374B Jul 25 12:07 treetop-1.4.9 drwxr-xr-x 8 marcc staff 272B Jul 25 12:07 tzinfo-0.3.29 When I run the gem list command, I get this: ~ marcc$ gem list *** LOCAL GEMS *** abstract (1.0.0) actionmailer (3.0.9) actionpack (3.0.9) activemodel (3.0.9) activerecord (3.0.9) activeresource (3.0.9) activesupport (3.0.9) arel (2.0.10) builder (2.1.2) bundler (1.0.15) erubis (2.6.6) i18n (0.5.0) mail (2.2.19) mime-types (1.16) polyglot (0.3.1) rack (1.2.3) rack-mount (0.6.14) rack-test (0.5.7) rails (3.0.9) railties (3.0.9) rake (0.8.7) rdoc (3.8) thor (0.14.6) treetop (1.4.9) tzinfo (0.3.29) As you can see, the mysql-2.8.1 gem directory is there but the mysql gem is not listed when I do gem list.
