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

@endel same here.

In addition, I had to use rvm master instaed of rvm latest.

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

This worked on my mac os x moutain lion 10.8.3, resolved the openssl issue.

rvm get stable && rvm install ruby-2.0.0

Hey Eric. I had you pegged as more of a JRuby kind of guy :)

@johnkpush: Love 'em both :)

@krisleech same

in the latest updates for RVM it is enough to:

rvm get head
rvm pkg remove
rvm install ruby

@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`

@i3zhe check rvm issues or open new one if the problem was not mentioned there yet => https://github.com/wayneeseguin/rvm/issues/

hey @i3zhe I just had the same issue. Try running brew install openssl That worked for me

@gabceb thanks, will try later at home

rvm pkg is obsolete.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
sudo apt-get install libreadline6-dev autoconf libgdbm-dev libncurses5-dev automake libtool libffi-dev

If got Error

Error running 'make -j8' or j2

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

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

getting error with rubygems on ubuntu, i've tried omiting ssl option and it worked

thanks for share

thanks for share

nice tip

$ rvm install 2.0.0 worked just fine for me.

To make it default: rvm use --default 2.0.0

rvm install 2.0.0-p353 work for me.

I have the latest stable rvm, so is there anything else we need to do for that flag?

good work!
