Answer 1

Ruby 2.2.0 requires the devel version of libffi, so this should help:

sudo apt-get install libffi-dev

Answer 2

I tried answer of Tomáš Dundáček but it did not work for me I have to install following to make it work

sudo apt-get install autoconf bison build-essential libssl-dev libyaml-dev libreadline6 libreadline6-dev zlib1g zlib1g-dev

Answer 3

Just as a side note: I had this problem with rbenv install 2.2.1 (and installing libffi-dev solved it) but not with the 2.2.2 version which is now out. You should use the last hotfix version anyway, so that could solve the problem. I'm interested to know if I'm the only one to had the problem with 2.2.1 and not 2.2.2.

Answer 4

Thought I'd add this here since the error is the same, but the cause is different (OpenSSL). The only thing that worked (after a few hours of trying a bunch of things) was uninstalling an old version of OpenSSL with homebrew.
