Previously, I ran apt-get install rails, but that only installed rails 2, so I subsequently ran gem install rails. The output of that command clearly references rails 3, not 2:
Fetching: railties-3.2.9.gem (100%)
Fetching: bundler-1.2.3.gem (100%)
Fetching: rails-3.2.9.gem (100%)
# ...
...but rails -v outputs Rails 2.3.14. Gah! I can't run my rails local server! Yet when I run gem list rails, the output is:
*** LOCAL GEMS ***
rails (3.2.9)
What am I to do to get the rails 3 rails command to work on the command line?
