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

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.

After several attempts I get:

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

I don’t think it’s the internet connection, I get the same errors at
home and at work. I think it’s best we just let this one go, I gave up.
I’ll probably just make a fresh install of everything.

thank you and kind regards,

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.

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/

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?

Ubuntu is excellent for rails.

And finally now what? Should I try and change to rials 3 via RVM?

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

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.

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?

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.
