Installing ruby 2.0.0 with RVM

Ruby 2.0.0 was released on February 24, 2013, on the 20th anniversary of Ruby's inception. Test out your apps and gems so you can be ready. You must install libyaml because Ruby 2.0.0 deprecated syck in favor of psych.

Make sure you have the latest RVM:

rvm get stable

Just run this in your favorite terminal after installing RVM:

## For Debian-based systems
apt-get install libyaml-dev

## For Fedora/CentOS/RHEL systems
## yum install libyaml-devel

## For Mac with Homebrew
brew install libyaml

rvm pkg install openssl
rvm install 2.0.0 \ 
    --with-openssl-dir=$HOME/.rvm/usr \
    --verify-downloads 1
rvm use 2.0.0

Enjoy!

Nice, I've had to install this way: (maybe I have an old rvm version?)

rvm install ruby-2.0.0-preview1  --with-openssl-dir=$HOME/.rvm/usr --verify-downloads 1

I used RVM stable. I had to export CC=clang before the RVM install on OS X.

rvm install 2.0.0 </code> should work better.

For Fedora/CentOS/RHEL the package should be: libyaml-devel

yum install libyaml-devel

@mpapis hi there, I followed your steps, but still get the ssl issue, any idea?

gem install rails --version 4.0.0.beta1

ERROR: Loading command: install (LoadError) cannot load such file -- openssl ERROR: While executing gem ... (NoMethodError) undefined methodinvokewithbuild_args' for nil:NilClass`

rvm pkg is obsolete.
what did the trick for me in OSX was:
brew install openssl;
rvm install 2.0.0 --autolibs=1

@rafapolo I'm getting "Unrecognized command line flag: '--autolibs=1'" when trying your solution. I have the latest stable rvm, so is there anything else we need to do for that flag?

$ curl -L get.rvm.io | bash -s stable
$ rvm install 2.0.0

works for me.

I met SSL error when doing $ rvm get stable

If I'm not mistaken, Rails 4.0.0 (beta) isn't using Ruby 2.0.0 (preview). Every time I followed your instructions it all worked until I checked the version number of both rails --version and ruby --version. Installing Ruby 2.0.0 forces you to use an older version of Rails, in my case Rails 3.2.13. Do you know if the final release of Rails 4.0.0 is expected to use Ruby 2.0.0?

Worked like a charm, thank you

For Ubuntu Also

If got Error

Error running 'make -j8' or j2

rvm get stable
rvm autolibs enable
rvm install ruby || rvm install ruby --with-gcc=clang

over 1 year ago ·

For older versions of rvm,

rvm get head
rvm reload
rvm get stable

And, on OSX, you might have to update to XCode 4.6.2
