Very simple situation. This is what I did:
$ rbenv local 1.9.3-p448
Then I opened a new tab in Terminal (on OS X) and while still in the same directory, I do:
$ ruby -v
and get back ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]. Then I do:
$ fish
$ ruby -v
and get back ruby 1.9.3p448 (2013-06-27 revision 41675) [x86_64-darwin13.1.0]
The .ruby-version file is present and contains only the text 1.9.3-p448. What is going on here?

With Nitrous.io the documentation states that other Ruby version managers may be used instead of RVM.
However, sudo is needed for installing rbenv
Is RVM currently the only option on nitrous.io?
If you do not wish to use RVM which is pre-installed then you can install rbenv. Run the following commands within your Nitrous.IO console:
$ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
$ git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
$ source ~/.bashrc
These steps can be found within the Octopress guide which utilizes rbenv on Nitrous.IO.
I have an .rvmrc file:
rvm use 1.9.3-p286#refinery --create
and changing to that folder yields:
Using /Users/neil/.rvm/gems/ruby-1.9.3-p286 with gemset refinery
$ ~/code/visioneng/ master* ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]
$ ~/code/visioneng/ master*
However, this clearly isn't what I asked for. What gives?
check if you do not overwrite PATH in any of your shell scripts/functions/aliases
I'm trying to use the MongoID-Devise generator template by doing this under Ubuntu and using RVM:
rails new myapp -m https://github.com/RailsApps/rails3-application-templates/raw/master/rails3-mongoid-devise-template.rb
I've also tried to download the file and do the generation locally, but in both cases, I get:
$: command not found
As according to the guides: Application Template, I'm using the command/options correctly...
EDIT:
The following commands gives me the following results:
rails -v --> Rails 3.1.3
ruby -v --> ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
The "$" you see at the beginning of the command is actually a convention that indicates a Unix console prompt. Don't include the "$".
I am at wit's end here and am turning to you all for some help on this f*#$^ encoding issue.
I am running on a private server with root permissions on Dreamhost. Here is a bit about my environment and versions.
$ `which ruby` -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
$ `which bundle` -v
Bundler version 1.0.15
$ `which rails` -v
Rails 3.0.9
Aside from this error, my rails app runs fine without issue. However, when I try to change the encoding a string by using the encode method it:
NoMethodError: undefined method `encode' for "foobar":String
encode should be defined but it is not! Encoding is found if I try in irb:
$ irb
ruby-1.9.2-p180 :001 > Encoding
=> Encoding
ruby-1.9.2-p180 :002 > "foobar".encode('utf-8')
=> "foobar"
But if I try using the rails console through bundle exec, Encoding is not found:
$ bundle exec rails c staging
Loading staging environment (Rails 3.0.9)
ruby-1.9.2-p180 :001 > Encoding
NameError: uninitialized constant Encoding
from /[REDACTED]/shared/bundle/ruby/1.8/gems/aws-s3-0.6.2/lib/aws/s3/extensions.rb:206:in `const_missing'
from (irb):1
ruby-1.9.2-p180 :002 > "foobar".encode('utf-8')
NoMethodError: undefined method `encode' for "foobar":String
Obviously the setup is not loading something correctly but I am not sure where to look to figure it out. What am I missing here?
UPDATE 6/19/2011
As Ryan Bigg pointed out, it is curious that the directory path for the gems is 1.8. However, running bundle exec shows that bundler is using the correct ruby and rails versions:
$ bundle exec which ruby
/path/to/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
$ bundle exec `which ruby` -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
$ bundle exec which rails
/path/to/shared/bundle/ruby/1.8/bin/rails
$ bundle exec `which rails` -v
Rails 3.0.9
Clearly something is wonky here… I just don't know what.
UPDATE 6/26/2011
Seamus asked for the $LOAD_PATH…
UPDATE 6/26/2011 (later)
Seamus asked for the Gemfile.lock and the pp ENV… In the ENV output, I found that the GEM_PATH was not correct. In my staging.rb environment file, I have:
GEM_HOME = "/home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180#[REDACTED]"
GEM_PATH = "/home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180#[REDACTED]:/home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180#global"
…which is obviously not being honored. Nowhere else in my code is there a mention of GEM_HOME or GEM_PATH
UPDATE 6/27/2011
Seamus asked for the .bundle/config contents…
UPDATED same idea (that GEM_HOME is messed up), but more suggestions
Your GEM_HOME is messed up, possibly because your PATH is messed up. You could try setting the following environment variable in your shell
$ export PATH=[your current path but with rvm's ruby 1.9 at the front]
Then run
$ bundle install
If that doesn't work, try also setting this in your shell
$ export GEM_HOME=[your ruby 1.9 gem home]
and then re-run
$ bundle install
New ideas from this answer: Using RVM, bundler does not install in proper gemset when gems are installed in a different ruby version
My RVM is installed as root.
When I'm trying to start unicorn socket, it prints
user#9001-3:~$ /etc/init.d/unicorn start
Starting myapp app: /usr/bin/env: ruby: No such file or directory
unicorn.
But if I type
user#9001-3:~$ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
/usr/local/rvm/gems/ruby-1.9.2-p180/bin/unicorn path exists.
My unicorn config: https://gist.github.com/1010519
/etc/init.d/unicorn doesn't know where to find Ruby because it's managed via RVM. Normally, your .bashrc or similar file is executed and sets up the environment; this doesn't happen in init scripts (or likely anything else executed by root).
The solution is to use wrappers. For example, to create a binary called system_ruby that loads up RVM's 1.9.2p180 environment and then executes ruby, execute the following:
rvm wrapper ruby-1.9.2-p180 system ruby
For more information and more details, check out this answer of mine, which addresses a similar problem.
Symlink also works,
which ruby<your version>
ln-s /ruby/path/ruby<your version> /ruby/path/ruby
Type :
which ruby (show the ruby bin path) then type this : ln -s (change_to_ruby_path) /usr/bin/env/ruby (construct the correct access for your system)
I had the same problem and this for me
rvm --default use <version>
