RVM was such a great tool to switch between various rubies and gemsets.
But from my last update of the rvm using
rvm get head, my shell hangs whenever I change the directory.
So, I thought it is the time to move on with rbenv.
First delete the rvm with the following cmd:
Delete the rvm specific code from your
~/.zshrc or whaterever files related to the shell you’re using.
Then install rbenv and rbenv-gemset via homebrew.
brew update brew install rbenv rbenv-gemset
Creating a global gemset
echo global > ~/.rbenv-gemsets gem install bundler cd project echo "project-gemset global" > .rbenv-gemsets bundle install
Whenever you create a gemset and want to share some gems like
bundler, install the bundler in global gemset as above and add the global gemset along with the project specific gemset in
.rbenv-gemsets file as above.

Sometime when upgrading RVM or just doing a fresh install and try to install Rubies, one might stumble upon a weird problem. I’ve also encountered such situations several times. Specially, when RVM brings breaking changes while updating. The following is the most recurring issue I’ve faced with. So, just documenting for this time so that I don’t have to Google it again.
rvm install ree ruby-1.8.7-p330 - #fetching ruby-1.8.7-p330 - #extracting ruby-1.8.7-p330 to /Users/andrew/.rvm/src/ruby-1.8.7-p330 ruby-1.8.7-p330 - #extracted to /Users/andrew/.rvm/src/ruby-1.8.7-p330 ruby-1.8.7-p330 - #configuring ruby-1.8.7-p330 - #compiling Error running 'make ', please read /Users/andrew/.rvm/log/ruby-1.8.7-p330/make.log There has been an error while running make. Halting the installation.
If you do it again, you’ll see the error

Skipping extract (use --force to force re-download and extract). ree-1.8.7-2011.03 - #installing ERROR: Error running './installer -a /Users/millisami/.rvm/rubies/ree-1.8.7-2011.03 --no-tcmalloc --dont-install-useful-gems -c --with-readline-dir=/usr/local/Cellar/readline/6.2.1', please read /Users/millisami/.rvm/log/ree-1.8.7-2011.03/install.log ERROR: There has been an error while trying to run the ree installer. Halting the installation.
When you see the log file, you’ll see something at the end of that file:

This error is due to the
Now you’ve got 2 options. One is to install
rvm pkg install readline or if you have
homebrew installed, you can install it via
brew update; brew install readline.
brew info readline will show the
So now, you opt for either way.
# if you go via homebrew way $ rvm remove ree $ rvm install ree -C --with-readline-dir=/usr/local/Cellar/readline/6.2.1 # if with rvm way $ rvm get head; rvm reload $ rvm pkg install readline $ rvm remove ree $ rvm install ree --with-readline-dir=$rvm_path/usr

I’m just posting a quick installation in rvm. Install ruby 1.9.3 if you haven’t or skip to the next block.
rvm get head rvm install ruby-1.9.3-p0 rvm reload rvm 1.9.3
Now lets install the ruby-debug gem. Follow the below simple steps:
cd ~/tmp wget http://rubyforge.org/frs/download.php/75414/linecache19-0.5.13.gem wget http://rubyforge.org/frs/download.php/75415/ruby-debug-base19-0.11.26.gem $ gem install linecache19-0.5.13.gem Building native extensions. This could take a while... Successfully installed linecache19-0.5.13 1 gem installed $ gem install ruby-debug-base19-0.11.26.gem -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p0 Building native extensions.
