No idea why but in the quest for more information, do you get any
errors?  Does the command work?

A few random thoughts ... show us output from those commands below.

$ cat ~/.railsrc

$ rvm current

$ rvm gemdir

go into that gemdir and have a look at the gems.

$ cat Gemfile

$ gem list rail  # Without s

$ which rails

$ ruby -ve ''puts 4''

For your reference, I am showing the output I see here in a recently
installed 3.2.1 project:

Sorry that I was not clear here. I meant the cat Gemfile to
be executed in your home directory.

$ cd
$ cat Gemfile

But probably, there is no Gemfile there.

Is there any chance that the 3.1.0.rc6 is used and has a known bug ?

Actually, something I don''t understand. IIRC (??) you said, you threw
away everything and reinstalled rails. But how come we have these
"old" versions or Rails then ?

What happens when you do this as a fresh new install :

I copied the output on my side in https://gist.github.com/1722491

$ cd <some test directory>
$ rvm install ruby-1.9.3 # this will install 1.9.3-p0
$ rvm use ruby-1.9.3
$ rvm gemset create new_rails
$ rvm gemset use new_rails
$ gem install bundler
$ gem install rails # this will install rails 3.2.1
$ rails new new_app --skip-bundle
$ # in previous tests, you never arrived here ?
$ cd new_app
$ vim Gemfile # active therubyracer
$ bundle install
$ rake environment # should not fail

HTH,

Peter

Really thanks for the instruction.

Here is the output after above instructions
https://gist.github.com/1722814

Yes, you are right it hang right on this step (I wait for 10 minutes and 
still the same)
"rails new new_app --skip-bundle"

I have two exactly "clone" machine. One I did not remove using rvm
(this
for backup because I don''t want to mess up my current development 
environment) and another one I remove everything using rvm. (This where 
I do the testing to figure out the problem with rails).
The reason you see "old" rails because the previous reference run on
the
machine which still have not removed everything. Sorry for the 
confusion,

So now, both this run on fresh rvm
https://gist.github.com/1722814
https://gist.github.com/1722825

And I still have problem. I kind of confuse where to troubleshoot 
further, may be the best way is to format everything and start from 
fresh Mac OS install

Ah, sorry I forgot to ask you to show the rvm version ....

$ rvm version # this is the latest "stable" version

rvm 1.10.2 by Wayne E. Seguin
<wayneeseguin-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>, Michal Papis <
mpapis-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
[https://rvm.beginrescueend.com/]


I presume you have a quite old version of rvm, since it sets you up with
this:

ruby-1.9.3-preview1


I wrote in my previous mail

#  $ rvm install ruby-1.9.3 # should install 1.9.3-p0

and that did not seem to succeed.

So, next try:

* on _both_  machines

$ rvm version   # this could be different and the root cause ??

* on the "test" machine

$ rvm get stable
... (download, build, install)
rvm 1.10.2 by Wayne E. Seguin
<wayneeseguin-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>, Michal Papis <
mpapis-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
[https://rvm.beginrescueend.com/]

RVM reloaded!
~/be$ rvm version

And then reinstall ruby

$ rvm reinstall ruby-1.9.3 # => check explicitly for 1.9.3-p0

$ rvm list

rvm rubies

   jruby-1.6.5.1 [ i386 ]
   jruby-head [ i386 ]
   ruby-1.8.7-p352 [ i686 ]
   ruby-1.8.7-p357 [ i686 ]
=* ruby-1.9.3-p0 [ i686 ]
   ruby-head [ i686 ]

# => - current
# =* - current && default
#  * - default

And hopefully it works now ?

HTH,

Peter

Hi Peter,

You really deserve the MEDAL of HONOR in helping ways to solve these.
So far, it still not able to pass that ton''s of ruby process problems.

https://gist.github.com/1723620

At least now, I know i have old rvm and be able to update it already.

Seems like there already several test to resolve it, replacing rails to 
ruby to rvm.

Honestly, this exact problem already half year, I just postpone it until 
I need to create a new rails problems from template

Let''s wait with that until it actually works :-)

Now you have new version of everything (I believe), and I see
you are on 64 bit Darwin 10.8.0

robinhood:junk106 steve$ ruby --version
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0]
robinhood:junk106 steve$ rails new new_app --skip-bundle
^C

I propose someone else with access to a Mac checks this out ?

Any ideas what changed at that time?

Thanks Peter,

Since I have machine to experiment with, in the near future, I might 
reinstall from fresh. In the past, this machine (Mac Book Pro and 
MacMini), Ruby on Rails with that simple statement work.

but somehow, don''t know what cause it and when it happen and why it 
happen, suddenly just stop working.

And the funny thing is, others than that ruby generations, "rails 
server" working just fine
