Forum: Ruby on Rails Starting rails server problem

Still fairly new to Ruby and Rails in general and trying to figure out
how to address this error.  I recently migrated to a new computer and
now I get this error message when I try to start the rails server.

-bash: /Users/user1/.rvm/gems/ruby-1.9.3-p125/bin/rails:
/Users/user/.rvm/rubies/ruby-1.9.3-p125/bin/ruby: bad interpreter: No
such file or directory

I know what the problem is and it's being caused because my ID from one
mac to the other changed from user to user1, now rails is still trying
to start the server using my old path.  I just don't know where I would
go to change that path and tell rails to look under user1 and not user.

Did you install rvm and ruby as the new user, or did you just copy files 
across?

Colin

I installed rvm, ruby, rubygems and rails from scratch.  However I had 
some apps and tutorials I was working on that I copied over from the old 
computer.

What do get (in the app that is failing) for
rvm info
ruby -v
rails -v

If those look ok does it work if you make a new rails project?

Creating a new rails app works as expected however when I try to start 
the rails server I get the following error:

The main issue I see is where it says Library not loaded: the path isn't 
correct and seems to be trying to reference my old ID and not the new 
one.  Where I would go to fix this I have no idea.

Would perhaps completely removing rails, ruby and rvm be a solution 
here?

Is that path to the current logged in user?

Not sure exactly which path you are referring to.  Previously you
mentioned user and user1, are those not the actual names?

You said you have only just installed them.

Colin

1. Yes

2. Correct, if you look on the error where it says Library not loaded:
/Users/derkdoijer/.rvm/rubies/ruby-1.9.3-p125/lib/libruby.1.9.1.dylib

It's still referring to my old username (I was using user and user1 as 
an example here) the usernames are derkdoijer and derkdoijer1

3.  I had them installed on my previous system and reinstalled them on 
my new system since this did not migrate over correctly.  I'm wondering 
if wiping the slate clean will potentially fix the problem.

Since you have not followed my request to insert your reply inline in
previous post and even worse have not even quoted the previous message
no-one finding this in the future will have any idea about what this
message is about.  Remember this is a mailing list not a forum (though
you may be accessing it via a forum-like interface).

Yes I see that now, have you got a user dekdoijer on the new system?
If not then are you sure you did not copy the .rvm stuff from your old
user directory across to the new one?

If I am right and you copied the .rvm stuff from the old user to the
new one then just running through the rvm and ruby install might not
have fully re-installed them, so paths to the old user are still
there.  I think you may be right to fully remove all rvm stuff and
re-install.

My apologies, I did not notice that in your original reply above and 
will reply inline from now on.  I do in fact access this via a forum 
like interface and was not aware that this was a mailing list.  Again, 
my apologies.

user derkdoijer does not exist on the new system.  You are most likely 
correct that .rvm was copied over and not properly reinstalled when I 
setup my new system. I used the migration assistant to migrate my files 
over to the new system.

would 'rvm implode' be the best way to go about doing this or is that 
overkill?

That sounds like a good plan, then you know you have removed everything.

Thanks for everything!

After some work got everything working again, mountain lion removing 
gcc-4.2 was not helpful at all but now that everything is reinstalled 
and setup correctly rails server starts as it should again.
