Question

So I installed ruby, gems and rails – however whenever I type rails I get the rails: Command not found. error.

I did a dump of my local gems, which I’ll include below

I also checked my gem environment setup (below)

 - RUBYGEMS VERSION: 1.8.24
  - RUBY VERSION: 1.9.3 (2011-10-30 patchlevel 0) [x86_64-freebsd8.1]
  - INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.9.1
  - RUBY EXECUTABLE: /usr/local/bin/ruby
  - EXECUTABLE DIRECTORY: /usr/local/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-freebsd-8
  - GEM PATHS:
     - /usr/local/lib/ruby/gems/1.9.1
     - /root/.gem/ruby/1.9.1
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - http://rubygems.org/

and echo’d my $PATH variable /sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/root/bin

I attempted to go into where the whereis command told me rails was installed

whereis rails
rails: /usr/local/bin/rails

and execute rails from there, again , I got rails: Command not found.

I am running FreeBSD on a VPS, and would like to learn some additional languages beyond PHP, but I can’t seem to figure this one out for the life of me … any help would be amazing.

Answer 1

I’m certain that your problem was caused by gems in the other gem directory, here:

/root/.gem/ruby/1.9.1

So for future readers, look in your other GEM PATHS.

(And then if that’s wrong I’ll update this answer appropriately.)
