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 using Ubuntu 11.10 and the terminal to install and run Rails. Here
is the process I've taken so far to setup Rails:
download and install Ruby 1.9.2 and Rails 3.1.0
-- I did this using sudo apt-get ruby1.9.1 and sudo gem install
rails
I made a new rails app using rails new path/to/app
I went to the new app directory and tried running rails server and got an
error about not having a JS ruby environment
I had to get a JS runtime environment for execjs so I downloaded 'therubyracer'
as well as 'therubyrhino' and added them to my gem file, one at a time like this:
gem
'therubyracer' then ran bundle install
After everything was successful with the install, I ran rails server again
-- with both runtime environments I have had similar errors:
Could not find libv8-3.3.10.4 in any of the sources
Run `bundle install` to install missing gems.
Could not find therubyrhino-1.73.0 in any of the sources
Run `bundle install` to install missing gems.
Bundle knows where these programs live, giving correct pathnames when I
enter bundle show libv8 or bundle show therubyrhino. They are both
in /usr/lib/ruby/gems/1.9.1/gems/_ where all the other gems are
located for the bundle install.
Does anyone know where this exception is coming up in the Rails source
code? Does anyone know how Rails is gathering the gems? Better yet,
anyone had this problem and know how to fix it?
Thanks so much,
Feav
Have you tried starting the server using bundle exec rails server?
This problem has been fixed in a newer version of Rails.
I'm a beginner programmer and I'm trying to get the rails server to run on OS X Lion. When I type "rails server" into the command line, I get this error:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:777:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:211:in `activate'
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1056:in `gem'
from /usr/bin/rails:18
What do you think a solution to the problem is? Any help you can provide would be greatly appreciated. Thanks!
You need to install the rails gem. You could probably do this by running bundle install inside that project.
Have you installed the Rails Gem?
gem install rails
Then do a gem list to see if Rails is in there.
It's also important that you be in the proper directory. So if you keep all of your apps in /apps/ make sure you are in /apps/my_app before calling the server command.
The Ruby bundled with OS X is too old for Rails 3.
I would recommended using 'rvm' to install the latest stable version of ruby-1.9.2-p260
Since installing ruby requires some compilation, make sure you have a gcc installed. You can install XCode to get an usable gcc.
To install rvm, you need bash, git and curl.
RVM: http://beginrescueend.com/
After that, you can use
gem install rails
Enjoy!
The Lion Server looks at a non-default path for the gem file
For example have a look at the first line of /usr/share/devicemgr/backend/devicemgrd:
#!/usr/bin/env GEM_HOME=/usr/share/devicemgr/webserver/gems GEM_PATH=/usr/share/devicemgr/webserver/gems RAILS_ENV=production /usr/bin/ruby
So to install the missing gems, make sure to install them at the required path:
sudo GEM_HOME=/usr/share/devicemgr/webserver/gems gem install rails
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.
I am trying to get the Rails tutorial by Michael Hartl going. I spent a lot of time fighting various libraries. So I removed all ruby software from my Ubuntu 10.4 system.
Then I installed Ruby 1.9.2.
$ ruby -v
ruby 1.9.2dev (2010-07-02) [i486-linux]
So far so good. Then I did
sudo gem install rails
After a long time, it finished the installation.
Then I ran
$ rails -v
bash: /usr/bin/rails: /usr/bin/ruby1.8: bad interpreter: No such file or directory
So...I have no /usr/bin/ruby1.8 on my system. How do I get Rails 3.0.3 to use my ruby at /usr/bin/ruby?
I appreciate any help you can give me.
Just to see if I could keep going, I tried
$ cd /usr/bin
$ sudo ln -s ruby1.9.2 ruby1.8
This let me keep going, but is it the right thing to do?
It took trying 3 different methods of installing and uninstalling Ruby, but I finally got it!
I found a great tutorial by Toran Billups which gives some great instructions. After analyzing what he did, it comes down to a few key concepts:
Some libraries that are independent of the Ruby version must be installed in the system (using "sudo apt-get").
Use RVM to install Ruby in your own account. i.e. no "sudo".
Use gem to install gems in your particular ruby environment. (i.e. no "sudo"). When you set 1.8 as the Ruby environment, the gems are installed in the RVM 1.8 tree in your environment. When you set 1.9.2 as the environment, gems are installed in the 1.9.2 tree in your environment.
Here, then, is the process.
Remove all Ruby programs (1.8.x and 1.9.2) and Ruby libraries from your Ubuntu 10.4 system.
Install RVM on your system, following the instructions at the RVM site(broken) RVM site.
Follow Toran Billups' tutorial, starting at the point where you install Ruby 1.8.7.
Follow the instructions at Michael Hartl's tutorial(broken) Michael Hartl's tutorial to get Rails 3.0 working with Ruby 1.9.2, github, heroku.com, rspec, spork, and autotest.
I had the same error after installing with RVM and opening new shells. The solution was to run:
$ rvm use 1.9.2 --default
P.S.
I'm running Ubuntu 10.04 and after two days of trial and error finally got rails 3 working with ruby 1.9.2. I highly recommend using RVM to install ruby a godsend!
By the sounds of it Bash is finding ruby1.8 when its running the #!/usr/bin/env ruby line from the rails script, even though it doesn't exist. Try /usr/bin/env which ruby to see exactly what interpreter it's trying to load.
I was also having a headache with this, and don't want to use RVM right now.
I saw that the shebang line for /usr/bin/gem was #!/usr/bin/ruby1.8 and that this was presumably the issue.
I made sure /etc/alternatives pointed to the correct gem script; this can be set with:
update-alternatives --config gem
Then I removed /usr/bin/gem and symlinked from /usr/bin/gem to /etc/alternatives/gem
It turns out the only difference in the gem scripts was the shebang line, so manually changing that would have worked too.
Solved by changing back the version of my current Ruby (using RVM) to 2.0.x.
When i installed rails (two days ago) it was under the 2.0.0 version. Yesterday i changed to 2.1.x. Today i tried the rails command and got the error.
So turning back to the RVM Ruby version i installed rails did the trick.
Sorry by the bad english.
P.S. Using Ubuntu 13.10
