Ruby on Rails with RVM on Ubuntu: no such file to load — openssl error

January 30, 2011

The following was adapted from:

RVM (Ruby Version Manager) is a must if you are working with different versions of Ruby. You can also create “gemsets” which are a set of gems that you can easily switch between. It isn’t perfect, however, on Ubuntu, you may hit some errors when using 1.8.7 when trying to use the openssl package for any non-system provided Ruby version.

Fixing openssl for Rvm-provided Ruby’s

RVM maintains the various versions of ruby in their own self-contained environments (folders) and will have trouble accessing some system-installed packages. On Ubuntu, apt is most commonly used to administrate Ruby. Using apt, openssl is a separate package ( libopenssl-ruby). This installs openssl for your apt-provided Ruby, which will most likely be /usr/lib/ruby/1.8/openssl. Rvm-provided Ruby’s can’t access this, however, so you need to build openssl for each rvm-provided Ruby you install.

The trick for this is to get the libssl-dev from apt before building openssl, otherwise you’ll have trouble configuring it. So, to get openssl on a rvm-provided Ruby, simply do:

sudo apt-get install libssl-dev
cd ~/.rvm/src/ruby-1.8.7/ext/openssl
ruby extconf.rb
make && make install
