I installed ruby, rails and gemsets using RVM on ubuntu as instructed on :
http://railstutorial.org/ruby-on-rails-tutorial-book#sec:rubygems
Now the problem is that everytime I reboot machine and open console, my RVM and rails settings are lost:
when I try "rails server" - rails is not found and all gems are lost too. I need to install rails and install other gems like heroku again.
Are you sourcing $HOME/.rvm/scripts/rvm into your shell in its .profile or whatever setup?
That would be the first thing to check.
Add this line:
source $HOME/.rvm/scripts/rvm
Try the following
rvm --default use 1.9.3

I am using Chef to provision a CentOS 6.5 box and install my Rails 4.0.4 app.
I installed RVM and Ruby 2.1.1
When I cd my_website, RVM will set the correct ruby version (gemset).
How do I tell Chef to bundle with the correct ruby version
currently I am using this:
execute "bundle-install" do
user "my_user"
cwd "/home/my_user/website/"
command "bundle install"
action :run
end
But that is not enougth, it's still trying to use ruby 1.9.3
RVM is a shell-based Ruby version manager. Since the Chef Client runs as root, it probably isn't executing the login shell. So things like .rvmrc and the actual loading of RVM are ignored. Handling this with Chef is a bit complicated. I would recommend looking at Fletcher's chef-rvm cookbook.
I installed RVM and installed 3 different rubies: 1.8.7, ree, and 1.9.2.
I have a Rails 3.0.9 project that uses 1.8.7.
Now when I try to run the 3.0.9 project, I get this error:
Could not find xml-simple-1.1.0 in any of the sources
However, the following command:
bundle show xml-simple
yields:
/Users/me/.rvm/gems/ruby-1.8.7-p334/gems/xml-simple-1.1.0
Looks right to me. What am I missing here? The application, when running, is clearly not seeing the right path. Yet Bundler, when run at the command line, sees it just fine. I am not certain where these paths are to be set. I am admittedly new to RVM, I installed it because I want to start a new edge project with 1.9.2.
Thank you for any help you can provide.
I needed to learn how to create a gemset, then switch to that gemset. You can always check your gem and ruby environment with rvm using:
rvm info
That's what clued me in. Once I "use"d the appropriate gemset where the gem was installed, it worked great.
I'm trying to setup passenger with rvm. I keep getting this error
Your RVM wrapper scripts are too old.
Please update them first by running
'rvm update --head && rvm reload &&

I did that still same problem

I'm using Fedora 14, Ruby 1.9.2, Rails 3.0.7
RVM is installed for multiuser
I also get this error when I do 'passenger start'
Cannot execute
'/home/antarr/.passenger/standalone/3.0.7-x86_64-ruby1.9.2-linux-gcc4.5.1-1002/support/helper-scripts/prespawn

I was having the same issue but found that using the rvmsudo command worked. Instead of
sudo passenger-install-apache2-module
try using:
rvmsudo passenger-install-apache2-module
It looks like Passenger 3.0.7 is confused by newer versions of rvm, but it seems like the instructions are incorrect and it's causing trouble. If the GEM_HOME environment variable is not set you get this error.
The correct instructions should be to use your particular version first:
rvm use 1.9.2
Although I got the same error as you, after that it worked for me.
If none of the above solutions work for you and you're getting the GEM_HOME warning
delete everything in .rvmrc
rvm get head && rvm reload && rvm repair all
gem install passenger
passenger-install-apache2-module
copy/paste the end message into your apache.conf
I am still having the same issue with passenger 3.0.19 if I tried to install on gemsets other than default and global. This is soooo troublesome. I have tried many suggestions and even rvm implode, then have everything brand new. but still hitting the brick wall. my forehead almost flatten. Hope not to lose my head!
Luckily, I found myself a fix. I found out that in i am in rvm multiuser envrioment and the issue arised if I switch to user gemset using command: "rvm user gemsets" which basically will create and use .rvm folder in user's home folder. e.g.: /home/.rvm instead of /ur/local/rvm folder. Since I do not know how to switch back and could not find any documention on how to, I did the following steps:
remove .rvm folder in the user home folder,
rm -rf ~username/.rvm
added back the user to rvm group (in multi enviroment, every new user need to be added to rvm group)
sudo usermod -a -G rvm username
re-login.
Now, as long as I am using shared rvm gemset folder, phusion passenger wont complaint.
Hope that helps someone.
I fixed the Permission Denied issue with:
chmod a+x /Users/tvd/.passenger/standalone/3.0.7-x86_64-ruby1.9.2-macosx-10.6/support/helper-scripts/*
Found it in comment section on the phusion.nl blog:

Using rvm I installed and am using Ruby 1.9.2p180.
I created a gemset called rails3tutorial and, using it, installed Rails 3.0.7, created "sample_app", then used bundle to install. Very nice.
Then I created a new gemset called rails310b1, installed Rails 3.1.0 Beta 1, created an app, and bundle install'd...but it turned out I was not actually switched to the rails310b1 gemset, and so I ended up installing to ruby-1.9.2p180's default gemset (is that #global?...). I then manually deleted all the gems that had been installed!
Then I switched to rails310b1, and bundle install'd, created an app, fired up the app -- golden.
Now I switch back to the rails3tutorial gemset, and cd to the app created using it, and I get errors when running rails commands like...
$ rails generate integration_test layout_links
/Users/paul/.rvm/gems/ruby-1.9.2-p180#rails3tutorial/bin/rails:19:in `load': no such file to load -- /Users/paul/.rvm/gems/ruby-1.9.2-p180#rails3tutorial/gems/rails-3.1.0.beta1/bin/rails (LoadError)
from /Users/paul/.rvm/gems/ruby-1.9.2-p180#rails3tutorial/bin/rails:19:in `<main>'
It's looking for /Users/paul/.rvm/gems/ruby-1.9.2-p180#rails3tutorial/gems/rails-3.1.0.beta1/bin/rails but why?! $PATH looks fine.
Any suggestions as to what is messed up and how to clean this up, or is it best if I wipe out all my gems/gemsets and start over?...
Thanks!
There is nice screencast with basics of RVM http://screencasts.org/episodes/how-to-use-rvm but it mostly comes to using rubies:
rvm install 1.9.3
cd ~/projects/my-app
touch Gemfile
rvm use --create --rvmrc 1.9.3#rails32
gem install bundler rails
bundle exec rails new .
bundle install
bundle exec rails generate integration_test layout_links
please note you need to prefix most of the commands with bundle exec there is my gem that should save you from this problem rubygems-bundler.
also make sure you use .rvmrc files for every project so when you switch dir in console the proper ruby environment is set, the --rvmrc switch used above will generate one for you.
I am using Ubuntu 10.10, RVM and Ruby 1.9.2 and trying to install Heroku for the first time. Ruby 1.9.2 is the default for RVM and the only version I have been using.
The gem install heroku worked but trying to run heroku leads to "command not found" error. The executables folder /home/mike/.rvm/gems/ruby-1.9.2-p0/bin is already in the PATH. However, I see that Heroku was installed in /var/lib/gems/1.8/gems. gem list heroku does not show any installed gem. Simply creating symbolic links in .../ruby-1.9.2-p0 did not solve the problem, though it gives a different error:
/usr/lib/ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem heroku (>= 0) (Gem::LoadError)
from /usr/lib/ruby/1.8/rubygems.rb:214:in `activate'
from /usr/lib/ruby/1.8/rubygems.rb:1082:in `gem'
from /home/mike/.rvm/gems/ruby-1.9.2-p0/bin/heroku:18
I don't understand gem and rvm well enough to know what to try next. I read in another question that Heroku supports Ruby 1.9.1 but not 1.9.2 but don't know if that is still true. If so, how does one use Rails and Ruby 1.9.x with Heroku?
The problem turned out to be related to sudo and Ubuntu. RVM depends on the rvm_path environment variable to get started. According to answers to another question, sudo does not preserve the PATH variable in some versions of secure Linux. I don't know if it should ever preserve the rvm_path variable, but in any case, it does not on my version of Ubuntu. So the result of sudo gem install is that the default, RVM-provided version of Ruby is not available during the installation, and the system-default is used. In my case that is version 1.8. The installation appears to succeed, but it is not going to the right gem version.
The solution was simply to use gem install instead of sudo gem install.
If 'gem list' doesn't show the Heroku gem then that would seem to be the problem (the error you posted occurs when running a Heroku command without the gem installed).
Have you tried installing it again? Any error messages?
It does work with 1.9.2.
Had the exact same problem on Mac OSX 10.6.5. Reinstalling without sudo worked in this case also. Thanks for the explanation... being a nube, I would have never figured it out.
