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

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 am new to Rails and have been trying to setup up my Mac to handle some development. I am currently in a project folder and trying to install a Gem and get this error:
*bash-3.2$ gem install pg
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /Library/Ruby/Gems/1.8 directory.*
It appears its trying to install this to the 1.8 directory. I would like all gems to be installed only for this project and not for everything.
Here is my folder structure for Rails projects.
Rails Projects:
Project 1:
Project 2:
How do I correct the issue with the gem installation so it only goes into a specific folder. This goes for the ruby version as well.
Thanks for the help.
You need to be using RVM, the Ruby Version Manager, found at http://beginrescueend.com/
I assume you already have installed XCode and Macports (or something like it).
Install rails using "gem install rails"
Use "rails new new-project" to setup your new rails project
Use bundler to add any new gems to your project http://gembundler.com/
Finally, if you want to use MySQL, there is a trick to getting the mysql2 gem configured properly on Mac. That is covered in this stackoverflow post.
Without installing RVM, which you should be doing anyway, you just need to use sudo to install the gems. By default, your user account does not have write permissions to the default gem installation directory.
sudo gem install pg
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 am trying to install rails and have installed rvm and am trying to install rails but it is saying I do not have write permissions.
$ gem install rails --version 3.0.7
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /var/lib/gems/1.8 directory.
When I try sudo it give me this error, I know that you can use --no-ri --no-r-doc but even when I did this rails was not installed properly. Does anyone have any ideas?
$ sudo gem install rails --version 3.0.7
Successfully installed rails-3.0.7
1 gem installed
Installing ri documentation for rails-3.0.7...
file 'lib' not found
Installing RDoc documentation for rails-3.0.7...
file 'lib' not found
from my experience with rvm, gems should't stay in /var/lib/
if you didn't specifically asked for this, there might be a problem with your rvm installation
if so, i would definetly recommend a clean rvm install by following ryan bigg's guide of installing rvm. i followed it every time and never ever had the slightest problem after.
hope this helps!
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.
