On a Debian system, if the Ruby complains about “LoadError: no such file to load — openssl” try to install this package libopenssl-ruby
$ sudo apt-get install libopenssl-ruby
Now test if the problem resolved:
$ irb -rubygems<br /> irb(main):001:0> require 'openssl'<br /> => true
Voilla, there is no more load error.
