Rvm and gem confusion

Rails
1

I’ve previously used Macports to manage ruby. Now I’ve installed rvm and
installed ruby 1.9.2. Seems to be ok. But I’m a bit confused of where
the gems are. So 2 questions:

  1. I have my gems in .gem. This is the “old” location. With rvm they
    should be in .rvm. I’ve created a gemset global. Will this then be
    available for all apps on the server?

  2. When trying to install mail with “gem install mail” I get “ERROR:
    While executing gem … (Errno::EACCES) Permission denied -
    /Users/me/.gem/specs”. Why (besides the permission issue)? Is it still
    trying to install in .gem?

This is probably better asked on the Ruby or RVM list. It certainly has
nothing to do with Rails.

You’re really a funny guy Marnen. I thought Rails was based on Ruby. :slight_smile:

I’m trying to install Rails 3. Besides this hopeless linear behavior
from Marnen, anyone who can assist me with an answer? Or should I ask in
the Ruby list instead and say that I’m trying to install Rails using rvm
and gem but be asked to jump over to Rails list instead as I happen to
mention Rails?

Of course it is. This list, however, is not for basic Ruby or RVM
questions, but only for issues specific to Rails. So your question is
off topic here. Please take it where it is on topic – that way it will
get seen by more people who can help.

Your problem is with RVM, not with Ruby or Rails.

Maybe your RVM is not running as a function that is causing gem env
confusion.
Check out the manual, Post Install section.

Run “type rvm | head -n1” and check if the return is “rvm is a
function”. And if it’s not, follow the instructions given in the
manual.
Hope this helps.

Thanks. :slight_smile:

And what is yours?

Hello,

I’m not sure if I got it well, but I’ll try my best. So have you
installed RVM already? It’s wise to install Ruby 1.9, then set it as
default, then install the gem - but not as super user! So without
sudo! This way it won’t be in your system files, it will be “Ruby-
vesrion-specific”.

Also it’s a good idea, hogy uninstall, reinstall rubygems, since
sometimes it’s wokring well around updates.

May I ask you to write here the output of theese commands:
ruby -v
gem -v
rvm -v
rails -v
gem list

and your OS? and which Rails are you using/would you like to use?

I think alost every info is here:
http://rvm.beginrescueend.com/

but feel free to ask here, or almost every other mailing list… don’t
care if others are not really helpful! :wink:
cheers, good luck,
Zoltn

Did you install rvm using sudo? If you sudo install it, it’ll make it
so you have to use sudo to install any gems. If you want to tell which
ruby you’re running (on a mac) type:

which ruby

shouldn’t be /usr/bin/ruby

I can’t remember but I don’t think so. I stand as owner for the .rvm
directory.

It’s the ruby installed by rvm.

Maybe I should start over. If I uninstall rvm will that mean I get rid
of the installed rvm gems as well? I presume so. Can I just delete the
.rvm directory?

Yes. But I had to use sudo as I got an error of some sort and a
reference to my previous gem, the .gemrc. Not sure what that was.

Perhaps it’s a good idea to uninstall and start over.

Thank you very much. Feels really good to read a post like yours. I
appreciate your effort to help. :slight_smile:

I’ve used Rails for a few years now, but I’m not the natural programmer
and I can get stuck on technical stuff, even though I feel at home in
the Terminal and such. This thing with rvm was new to me, and yes, a bit
confusing.

What I don’t understand is how my old Rails 2 apps will deal with rvm.
Will they use my old gems and run as before even though I’ve set rvm
with 1.9.2 as --default? Well, it looks like they do but I’m not sure
which gem is used and where.

I recently had to reinstall rvm when I was upgrading from rails 3.0.0
to rails 3.0.3 (maybe too harsh but it worked), so in order to remove
the cached gems (on a single user install), I removed all the stuff in
$HOME/.rvm/gems

Btw, I don’t think you should’ve used sudo in the first place so maybe
just doing a fresh single user install without sudo will help you.

AFAIK, deleting .rvm is the recommended way on rvm’s site to delete a
single user install.

AFAIK everything related to RVM is stored inside ~/.rvm. I’ve
reinstalled before by simply deleting the directory and reinstalling.

If you want to know details about your RVM environment use…

rvm info

It will tell you where to find the gem folder and exactly what gemset
you’re using. All of this information can be found in the RVM docs on
their web site.

I was able to delete all in my previous location. Now I can start over
using rvm.

Thanks. Everything seems to be ok now, kept in rvm.

Yes, I’ve realized that’s the way to go. Trying to figure out how to do
it. Thanks.

I have found that making a gemset for each of my apps has been working
nicely, and makes them easy to find, i.e.

.rvm/gems/ruby-1.9.2-p0@wavelineup3/gems

Where wavelineup3 is the gemset I created under ruby-1.9.2-p0
installation
for one of my apps. See: http://rvm.beginrescueend.com/gemsets/creating/

Robert W. wrote in post #965531:

Once you get your gemsets configured look into using .rvmrc files in
your projects to automate the switching of your environment.

rvm gemset create my_gemset

rvm use 1.9.2@my_gemset

my_project
→ .rvmrc

rvm 1.9.2@my_gemset

http://rvm.beginrescueend.com/workflow/rvmrc/

And don’t forget to set your default interpreter:

Thanks. :slight_smile:

Besides rvm and the gem directory there I have a .gemrc in my home
directory and a .gem directory. Not sure why I have it there. It stops
my installation of Rails 3, complaining about permissions of the .gemrc.
Is that something I’ve created or has it to do with Mac OS Snow Leopard?
That is, can I delete them?

It sounds to me like you have permission issues with your home folder.
Anything in your own home folder should be fully accessible by you. I
don’t think this issue is directly related to rvm or RubyGems itself. I
think you may have basic OS permission issues on your machine.
