Strange... but this is what I got :
$ gem list | grep rvm
>> rvm (1.11.3.3)
$ gem uninstall rvm
>> INFO: gem "rvm" is not installed
How can that be possible? The root of this problem probably stems from me downloading the latest RVM and finding that it does not work with the latest version of POW. Thus I had to implode RVM and reinstall an older version. Since then when I do a cap deploy, I get the classic :
`<top (required)>': RVM - Capistrano integration was extracted to a separate gem, install: `gem install rvm-capistrano` and remove the `$LOAD_PATH.unshift` line, note also the 'set :rvm_type, :user' is now the default (instead of :system). (RuntimeError)
Any ideas?
I recently encountered the same rvm error:
"RVM - Capistrano integration was extracted to a separate gem, install: gem install rvm-capistrano and remove the $LOAD_PATH.unshift line, note also the 'set :rvm_type, :user' is now the default (instead of :system). (RuntimeError)"
Doing what the error suggested did not work for me at all.
What did work for me was to do: rvm -v
When I did this I saw that my rvm version was rvm 1.13.0
Using "rvm get" I did "rvm get 1.12.0" but still got the error
Then I tried "rvm get 1.11.0" and then presto, my rvm started working again.
I'm not 100% sure what caused the error in the first place but I think it all began when I tried to upgrade rvm with rvm get stable after I was unable to install some gems. I found out that I wasn't able to install gems anymore due to the fact that I had updated my xcode to 4.3.2 and apparently Apple changed their c complier which doesn't play nice with rvm.
Hope this helps someone.
Are you in a gemset? If so, that gem might be in the interpreter's unnamed gemset or the global gemset. If so, try
rvm use 1.9.3
gem uninstall rvm
or
rvm use 1.9.3#global
gem uninstall rvm
I just ran into this error as well. The error you ran into was because of the recent capistrano update. If you add rvm-capistrano to your gemfile and remove the $LOAD-PATH.unshift line from your capistrano deployment file it should work, at least it did for me.
That would be correct. Its in the 'global' gemset. This gemset is 'mixed in' to both the 'default' gemset and any gemsets you actually create.
Thus if you have Ruby 1.9.3 installed, for example, (rvm install 1.9.3) it will be installed into that ruby's 'global'. You can verify this by doing 'gem list rvm -dl' which will show you the name, version, description, and location on the disk of the requested gem.
∴ gem list rvm -dl

rvm (1.11.3.3)

I don't know why you want it removed, but you would do as Abe stated as the second choice.
To give more details, RVM works with POW, this is known issue: https://github.com/37signals/pow/issues/271
the easiest solution(in project dir):
rvm env . > .powenv
The version of RVM might not be compatible with POW. You can remove RVM and then install the most current version.
The problem is that RVM 1.12 and up does not play well with Capistrano.
So uninstall your RVM, then get RVM 1.11 (rvm get 1.11.0).
Nathan got it right: https://stackoverflow.com/a/10306090/294449
You used to have to do the unshift in your deploy.rb but the latest versions of RVM have made that hack no longer necessary. Just remove it and add the rvm-capistrano gem to your Gemfile. It works like a charm.

When attempting to run any rake, rails or bundle commands, I get following error:
/home/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': libcrypto.so.1.0.0: cannot open shared object file: No such file or directory - /home/username/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/x86_64-linux/digest/sha1.so
I have tried rvm pkg install openssl, rvm remove 1.9.3, rvm reinstall 1.9.3, reinstall bundler and all gems. I read on another forum that I may have to uninstall rvm, ruby and rails and start from scratch. Ugh - really?
Thanks in advance.
you need to read and follow the instructions displayed with:
rvm requirements
then remove the rvm installed openssl:
rm -rf $rvm_path/usr/
and reinstall ruby:
rvm reinstall 1.9.3-p194
I had tons of gems on my local machine which I were installed before and after RVM, so I decided to wipe them all and reinstall. Everything seemed to go ok, except bundler:
gem list
.....
bundler (1.1.3, 1.0.22)
I don't know why 1.0.22 is still there, and I can't figure out how to get rid of it!
$ gem cleanup
Cleaning up installed gems...
Attempting to uninstall bundler-1.0.22
Unable to uninstall bundler-1.0.22:

UPDATE 1
Path info as requested by Andrew
/Users/brandon/.rvm/gems/ruby-1.9.3-p125-perf#global/gems/bundler-1.0.22/
What's most likely happening is that the two versions of Bundler are installed in two different gemsets, one of which is inheriting from the other. 1.0.22 is probably installed in the global gemset (rvm use #global), or "root" gemset (rvm use <ruby_version>). Once you're in the gemset that has 1.0.22 installed, you should be able to remove it with gem uninstall bundler.
I recently started learning Ruby and Ruby on Rails, and have watched a plethora of getting started materials. I have been finding lately that I keep getting errors where gems won't install or they will be installed but they can't be used for some reason, and I have decided that I want to remove everything down to once again just having Ruby installed and start over with the installation. One training video had me install most of my gems with RVM, so I don't know if that changes anything.
So in short my question is "How to I get rid of RVM, Rubygems, and all installed Gems so that I can start over with just Ruby?"
Edit: I am on Mac OS 10.6
gem uninstall -aIx
Uninstalls all gems without prompt.
Options
-a, --[no-]all Uninstall all matching versions
-I, --[no-]ignore-dependencies Ignore dependency requirements while
uninstalling
-x, --[no-]executables Uninstall applicable executables without
confirmation
From the RVM support site:
RVM installs everything into ~/.rvm.
To remove RVM from your system run 'rm
-rf ~/.rvm'. You may have one additional config file in ~/.rvmrc and
of course the RVM hook in your
bash/zsh startup files.
So, just go to the command line and type rm -rf ~/.rvm
All the installed gems are in the ~/.rvm folders, so doing the above will remove the gems and installed rubies in one go.
Gems you added pre-RVM with the default ruby install can be removed by typing this at the command prompt:
for x in `gem list --no-versions`; do gem uninstall $x -a -x -I; done
For Windows and Unix copy/paste in command prompt (Ruby 1.9.x).
ruby -e "`gem list`.split(/$/).each { |line| puts `gem uninstall -Iax #{line.split(' ')[0]}` unless line.strip.empty? }"
using RVM, you could just type...
rvm gemset empty GEMSET
where GEMSET is the gemset which you would like to empty. then...
install bundle
yum install bundler and finally
bundle install
rvm implode (see cli docs) seems to work - and it even tells you where to look at for leftovers
This is work for me on Ubuntu 16.04. For me, when I was executing
command rails -v it throw errors because of NameError. I have
installed 3 version of rails (4.2.0, 4.2.6, 5.0.0.1). I was trying
to uninstall unnecessary gem using command gem uninstall rails -v
version number but I won't able to, but I find a way to solve
this problem. In order to uninstall all gems, you have to loop
through all entries in gem list with bash scripting. This method is
very inconvenient. Thanks to Rubygems 2.1.0, you now could do it
with one command.
STEP - 1
Firstly, please make sure you upgrade your Rubygems to 2.1.0 or
newer. For this run this command (Incase you are working on an older
version. You can check your gem version using this command any one
of them gem -v or gem --version)
gem update --system
gem --version
STEP - 2
Run this command in you terminal
gem uninstall --all
Step - 3
Install gem bundles (it is not necessary I think just for
precautions)
gem install bundle
Step - 4
Install the rails on your system using this command
gem install rails -v specific version you want to install you can check the rails version on the official site rails all versions
example :- I have installed rails 4.2.6
version, you install as per requirement.
gem install rails -v 4.2.6
Step - 5
Finally check the version of installed rails framework application
by Using basic command rails -v. It will echoed the current
version of rails frameworks. Enjoy :)

Step 1:
I first kept running into an error that said:
You don't have write permissions for the /usr/bin directory
To get permission, I became a root user with (this is potentially dangerous for reasons beyond my current understanding):
sudo -s
Credit
Step 2:
Then, I kept running into an error that said:
[gem] cannot be uninstalled because it is a default gem
This allowed me to uninstall everything:
for i in `gem list --no-versions`; do gem uninstall -aIx $i; done
Credit
FWIW, there are some weird cases where gems are installed but not really installed:
This should do the trick reasonably reliably.
gem uninstall -Iax `gem list | grep default | awk '{print $1}'`
Trying to install the new Rails 3 release on OSX 10.6.
Have never touched Ruby or Rails on this machine since purchased.
I was able to get rvm and get Ruby 1.9.2. installed. From there, I am stuck.
I tried:
rvmsudo gem install rails -v 3.0.0
sudo gem install rails --pre
sudo gem install rails
sudo gem update rails
And I get the same result error each time:
ERROR: While executing gem ... (Errno::ENOENT)
No such file or directory - /Users/kevin/.rvm/gems/ruby-1.9.2-head#rails3/cache/activesupport-3.0.0.gem
If I do gem list, it says LOCAL GEMS and doesn't list anything.
I have read a few walkthroughs but honestly none of them address this issue and its kind of pissing me off. Why is this so difficult to install? Would love to learn it if someone could help me get it running.
I was trying to follow this:
http://eddorre.com/posts/installing-rails-3-beta-4-using-rvm
and this:
http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard
Which is actually linked from the ROR guides website. Am I missing dependencies? How do I get them in?
If I do rails -v I get:
rails -v
/Library/Ruby/Site/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)

Older versions of rvm had a bug that can cause your ruby versions to get crosswired because the OS can cache executable paths for the which command (particularly if you are using zsh). See this long, detailed, mind blowing post by Yehuda Katz on the subject.
What I had to do this morning:
rvm update && rvm reload # update rvm
rvm gemset delete rails3 # delete old gemset
rvm install 1.9.2
rvm use 1.9.2
rvm gemset create rails3
rvm use 1.9.2#rails3
which ruby # check to be sure the ruby interpretter is properly set to 1.9.2
hash -r # if ruby interpretter is not pointing to 1.9.2
gem install rails
which rails # check to be sure we are using rvm version of rails
Note: On newer versions of rvm, you will have to use rvm get stable instead of rvm update
You don't need to use sudo when installing gems with rvm. If you follow the directions here to get RVM installed, you should be able to just do rvm use 1.9.2; gem install rails --version 3.0.0.
You don't have to specify version 3. If you have 1.9.2-p0, it will automatically get rails 3 when you rvm gem install rails 3. note: no sudo. I think when you use sudo it makes it use the system-installed ruby. If you think you need sudo, use rvmsudo.
Things probably got messy because you were following guides based on the pre-stable release of rails, which involved many other things. If you like, you can try uninstalling rvm and re-doing everything. It really isn't all that difficult.
Remember, you need 1.9.2, 1.9.1 won't work.
curl -O http://rvm.beginrescueend.com/releases/rvm-install-head
sh rvm-install-head
rvm install 1.9.2-p0
# also remember to edit your bash profile and add the required lines
# verify that 1.9.2-p0 shows up there
rvm list
# makes it so you're using it, and sets it as the default
rvm use 1.9.2-p0 --default
# verify this happened. should have => 1.9.2-p0 in the list
rvm list
# verify the version
ruby --version
# should automatically get 3.0
# `rvm gem install` installs it for every single installed ruby version
# in my experience
gem install rails
When you did rvm gem install, I think it installs it for every ruby version you have registered with rvm (at least it happened in my experience), so my assumption is that it was trying to force install rails 3 for an older ruby installation, which was missing the required gems.
Take it easy, not many commands are required. If you find yourself having to do 'hacks' or workarounds, then you're doing it wrong. Thankfully it's easy to start over. To remove rvm, just do rm -rfv ~/.rvm and also rm ~/.rvmrc if it's there.
Let me know how it goes.
working through this myself as new user mac osx blah blah
seems like a cache directory doesn't get made, try
mkdir $HOME/.rvm/gems/cache
so far so good after that...
I am running into the same problem (tried uninstalling and installing like Blaenk suggested)

After doing "rvm update && rvm reload" rvm got updated to 1.04 (instead of 1.02 which I got via the recommended GIT install yesterday!?) it worked nicely.
The solution worked for me, with a few tweeks:
Instead of using rvm update, I had to use rvm rubygems. Then, after doing all the work from post 2, I had to execute bundle install and I entered rvm use 1.9.2#rails3 to my .rvmrc file. Everything now works like a charm, even when starting a new shell or terminal session. The full list of commands I used is:
>> NEW >> rvm rubygems
rvm reload # update rvm
rvm gemset delete rails3 # delete old gemset
rvm install 1.9.2
rvm use 1.9.2
rvm gemset create rails3
rvm use 1.9.2#rails3
which ruby # check to be sure the ruby interpretter is properly set to 1.9.2
>> DID NOT NEED >> hash -r # if ruby interpretter is not pointing to 1.9.2
gem install rails
which rails # check to be sure we are using rvm version of rails
>> NEW >> bundle install
>> NEW >> cat 'rvm use 1.9.2#rails3' > .rvmrc
Followed these instructions, and found them very useful for rvm installation. Hope they work for you.

Doing this after the rvm update and reload worked for me:
rm -rf .bundle && bundle install
How do you update rubygems under rvm when ree is your default vm (on Snow Leopard)? I am doing:
$ rvm ree gem update --system
This results in things looking like everything went fine:
Updating RubyGems
Updating rubygems-update
Successfully installed rubygems-update-1.3.7
Updating RubyGems to 1.3.7
Installing RubyGems 1.3.7
RubyGems 1.3.7 installed
[...]
RubyGems installed the following executables:
/Users/douglassellers/.rvm/rubies/ree-1.8.7-2010.02/bin/gem
but when I run gem --version it still says 1.3.5. Doing a which gem points at ree version of gem.
Anyone know how to get rubygems to update with RVM?
Now you can just do :
rvm rubygems latest
Or you can define which rubygems you really want. https://rvm.io/rubies/rubygems/
The problem, I think, is the initial command (or what you expect that command to do):
$ rvm ree gem update --system
That tells rvm to pass the gem update --system to the gem under ree, but it doesn't switch you to that particular Ruby interpreter. You continue using whatever interpreter you have set in that shell (whether by default or because you switched manually earlier in the shell session).
As an example, my default interpreter is Ruby 1.9.2. If I pass this command: rvm 1.9.1 gem install pony, then the Pony gem is installed for Ruby 1.9.1. However, I'm still using Ruby 1.9.2 after that installation is finished. If I enter irb and try require 'pony', I get a load error. If I run rvm 1.9.1 and then enter irb, Pony is installed and loads fine.
So as Brian says in his comment to your post, you could switch manually with rvm use ree. Alternatively, you could switch your initial command to this:
$ rvm ree
$ gem update --system
$ gem --version
rvm suggested me to use something like this:
rvm ruby-1.9.3-p327#mygemset do gem update --system
It is an unusual problem.
If it is not yet resolved, consider using
rvm --default use ree
which ruby
which gem
this should show you if you are in the right version.
install gems either using rvm or directly.
