Installing ruby-2.0.0-p0 with rbenv BUILD FAILED

Question

So I tried to install ruby through rbenv on my new ubuntu 12.04LTS running on VirtualBox.

I got rbenv from https://github.com/sstephenson/rbenv and ruby-build from https://github.com/sstephenson/ruby-build.

and then i run the following but build fails :(

rbenv install 2.0.0-p0
Downloading ruby-2.0.0-p0.tar.gz...
-> http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p0.tar.gz

The Ruby openssl extension was not compiled. Missing the OpenSSL lib?

Any help would be appreciated. Let me know if you need any more details. Thanks!

Answer 1

You are going to need libssl-dev. For best results install all of the requirements which rvm autolibs function will install for you. Some of them (like sqlite3) presume that you will ultimately be wanting to install Rails, but aren't harmful if you don't need them.

Answer 2

Most probably you need the openssl extension as a prerequisite :

sudo apt-get install openssl

should to the trick. Relaunch your RBENV install afterwards.
