Rails: Command not Found after successful install - ruby-on-rails

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]

- RUBY EXECUTABLE: /usr/local/bin/ruby
- EXECUTABLE DIRECTORY: /usr/local/bin
- RUBYGEMS PLATFORMS:
- ruby
- x86_64-freebsd-8
- GEM PATHS:

- 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

If you installed Rails only via Bundler, then rails will only be accessible if you run bundle exec rails.
A "naked" rails command will only exist if you gem install rails directly without Bundler.

Answer 2

If you are using rbenv, it is possible you will need to run rbenv rehash after installing your dependencies for you rails application. ie. bundle install
From digitalocean:
Whenever you install a new version of Ruby or a gem that provides commands, you should run the rehash sub-command. This will install shims for all Ruby executables known to rbenv, which will allow you to use the executables:
Hope this helps!

Answer 3

If your app is running in production but can't find rails command on root then this might help:
run
script/rails c ENV
Instead of
rails c ENV
I had the same issue and resolved it this way. The app was running with nginx/passenger but wasn't able to run rails console/ rails server on production.

Answer 4

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.)

Answer 5

I just encountered this same problem under another scenario where I installed rails along with rvm on ubuntu-20.04.
I had to add the following line to my ~/.bashrc ( or `~/.profile')
# Where you installed rvm...
source ~/.rvm/scripts/rvm
