Have you installed rails inside rvm? Try gem install rails Note, no sudo.

After several attempts I get:

sebah@sebah-laptop:~/rails$ gem install rails ERROR: Could not find a valid gem 'rails' (>= 0) in any repository ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)     too many bad responses (http://rubygems.org/latest_specs.4.8.gz)

So where did those astericks come from? You have a problem with your rvm ruby installation. Here’s what I see when I type $(which ruby) --version bash-3.2$ __rvm list rvm rubies =* ruby-1.9.3-p194 [ x86_64 ]

=> - current

=* - current && default

* - default__bash-3.2$ **which ruby

/Users/richardlloyd/.rvm/rubies/ruby-1.9.3-p194/bin/ruby**bash-3.2$ **$(which ruby) --version ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin12.0.0]**bash-3.2$ My suggestion is to uninstall your ruby-1.9.3-p194 and install a clean copy.

Do you have any problems with your internet connection? Is there a proxy server for your connection?

Hi,

I am back with a new problem. Today I've installed Ubuntu 12.04 and after some trouble also

Ruby (output for ruby -v): ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]

and Rails (output for rails -v): Rails 2.3.14

I say trouble, because when I've installed with RVM I couldn't use them. The system kept saying unknown command for ruby and rails and it suggested to install via apt-get install. So I did. Still nothing. Then I ran the RVM installs again and now everything appears to be in order.

However (there's always however with me lately), when I run "rails new tasks" rails actually generates "new" as the application folder. And after "cd new" + "rails server" rails generates another application called "server".

What can I do?

thx seba

You should not have used apt-get if you are using rvm. But since you have now got it working with rvm that is ok.

What can I do?

You can use rails 3. The rails command has changed since version 2. The current version of rails is 3.2.8. If you really want to use rails 2 then the guides can be found at http://guides.rubyonrails.org/v2.3.11/

This was the only way at the time I could get it working.

I don't want to use rails 2, this was all installed by default as I described above. Are these issues related to Ubuntu? Are other distributions more aproppriate for RoR? And finally now what? Should I try and change to rials 3 via RVM?

Ubuntu is excellent for rails.

gem install rails will install the latest version of rails in rvm. Note /no/ sudo, because you are using rvm. gem install rails --version a.b.c will install version a.b.c

I followed the guide you recommended and it works like a charm now.

Thank you and kind regards, seba

This is getting really embarrassing. Today I get the error "bad interpreter" after running the new app command:

rails new app bash: /usr/local/bin/rails: /usr/bin/ruby1.8: bad interpreter: No such file or directory.

I've made no changes since the previous app creation, other than system updates today.

Ruby works fine, Rails doesn't. I've uninstalled and re-installed Rails and the error remains.

Are you using rvm? If not then I advise that you do.

which tutorial are you following?

the one you posted from sudobits. If this is regarding my last post which I have already deleted, the bad interpreter error occurs every time I start my computer. If I load the RVM via

source ~/.rvm/scripts/rvm

then it works. Why doesn't it load automatically? regards, seba

You can't delete a post on a mailing list (which this is), we have all already received it.

Have you followed this instruction from the command rvm notes

  * If you wish to use RVM in an interactive fashion in other shells     then place the following line at the end of your shell's loading files     (.bashrc or .bash_profile for bash and .zshenv for zsh),     after all PATH/variable settings:

    [[ -s "/home/colinl/.rvm/scripts/rvm" ]] && source "/home/colinl/.rvm/scripts/rvm" # This loads RVM into a shell session.
