trouble with new app in rails

[Sebastjan H.]

Hi,

I've just installed the latest gem version and also rails. Everything
went ok. I am using Ubuntu 11.10 with ruby 1.9.3-p194.

However, when I try to create a new application, I get:

---------------------------------------------------------------------------
/usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:247:in `to_specs':
Could not find railties (>= 0) amongst [] (Gem::LoadError)
from /usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:256:in
`to_spec'
from /usr/local/lib/site_ruby/1.8/rubygems.rb:1231:in `gem'
from /usr/local/bin/rails:18
---------------------------------------------------------------------------


when I want to get the rails version I also get this:
---------------------------------------------------------------------------
/usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:247:in `to_specs':
Could not find railties (>= 0) amongst [] (Gem::LoadError)
from /usr/local/lib/site_ruby/1.8/rubygems/dependency.rb:256:in
`to_spec'
from /usr/local/lib/site_ruby/1.8/rubygems.rb:1231:in `gem'
from /usr/local/bin/rails:18
---------------------------------------------------------------------------

seba

It seems that you still using ruby 1.8. 

Try : 

ruby -v 

And show me the output. If it's not ruby 1.9.3-p194, just install this version of ruby 

rvm install 1.9.3-p194 ( if you are using 'rvm' as ruby management tool )

Keep me posted 

;)

I thought so too, however, ruby -v gives:

ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]

how would I check for and completely remove version 1.8?

I strongly advise using rvm. Then you will have full control of ruby
and gem versions.

My guess is you've got something wrong in your shell environment.  What do you see when you type:

    $(which ruby) --version

NOTE: this is proper syntax for sh, bash, or ksh.  For csh use: `which ruby` --version

Try this as well :

and retry :)

I've checked my ubuntu program centre and there I have something called
a transitional package for ruby 1.8 (I am backtranslating from my
language). If I try to uninstall it I'd have to uninstall some
dependencies and I am not sure if I may.

[Colin Law]

No need to do that, your are using rvm so it should be using the
version installed under rvm.
Can you post the complete output from trying to create a new rails app.

Colin

[Sebastjan H.]

Colin Law wrote in post #1070094:

I've uninstalled the transitional package anyways and it didn't help. It
still tries to access the location below.

The entire output:

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

After several attempts I get:

[Rick]

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

[Colin Law]

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/

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?

[Colin Law]

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

See Sebastjan H. i m also new to rails, but a week ago i installed Ubuntu 12.04 for rails development from the link below

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

Thank you and kind regards,

[Sebastjan H.]

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.

[Colin Law]

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

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.
