I’m reposting this here from my original post on Superuser[1], to hopefully get more relevant feedback from more experienced RoR users. I need to get a RoR environment up and running, because I have a client that needs some RoR work done on her website. Although I’m new to RoR, I’m a quick learner and was expecting installing and setting up the environment was easy, so I could focus my effort on site development. I’ve already spent five days trying to get the environment up so I could just begin working. I’ll probably have follow up questions to this group (seems I can’t get script/server to work at all) - but for now, this is the immediate concern. Update #3: Starting over from scratch, shortened this post, decided to re-install a clean copy of Ubuntu 10.04 on a VM and go through the walk-through[0] again. So, all the steps go without a hitch. As root: root@ubuntu:~/rubygems-1.3.7# ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [x86\_64-linux] root@ubuntu:~/rubygems-1.3.7# gem -v 1.3.7 root@ubuntu:~/rubygems-1.3.7# rails -v Rails 2.3.8 Now, as myself (in a separate term): emptyset@ubuntu:~$ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [x86\_64-linux] emptyset@ubuntu:~$ gem -v /usr/local/lib/site\_ruby/1.8/rubygems.rb:10:in `require': no such file to load -- rubygems/defaults (LoadError) from /usr/local/lib/site_ruby/1.8/rubygems.rb:10 from /usr/local/bin/gem:8:in `require’ from /usr/local/bin/gem:8 emptyset@ubuntu:~$ rails -v bash: /usr/bin/rails: Permission denied So, this appears to be a permissions issue, but I don’t understand why. Specifically, if I have to start making things go+rx all over the place, I really need to understand which specific files need the permissions change.

I installed Ruby and Rails on Ubuntu 10.04 by following this guide: [RubyOnRails - Community Help Wiki](https://help.ubuntu.com/community/RubyOnRails). Everything went well. Quick steps: 1. > sudo apt-get install ruby-full build-essential 2. Download and install latest rubygems. Do not use apt-get because rubygems update itself and corrupts apt-get. 3. > sudo gem install rails 4. test your environment! \> rails ~/my\_test\_app On Wed, Jun 30, 2010 at 2:03 PM, emptyset [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > ## Now, as myself (in a separate term): bash: /usr/bin/rails: Permission denied > > You received this message because you are subscribed to the Google G. “Ruby on Rails: Talk” group. > To post to this group, send email to removed\_email\_address@domain.invalid. > To unsubscribe from this group, send email to removed\_email\_address@domain.invalid. > For more options, visit this group at [http://groups.google.com/group/rubyonrails-talk?hl=en](http://groups.google.com/group/rubyonrails-talk?hl=en). – Filipe Quadros Borges email: removed\_email\_address@domain.invalid msn: removed\_email\_address@domain.invalid ---

I would strongly suggest you look into rvm to manage your ruby/rails environments. But you might also want to install gem as your own user as opposed to root. The new gems will be kept somewhere in your home directory. - Victor ---

Thanks! I updated my answer on SU and linked to this post. My best guess is that: apt-get install ruby rdoc libopenssl-ruby build-essential Doesn’t quite cover everything that’s needed to run gem effectively…ruby-full on a clean VM install worked great. Much appreciated. ---
