Can't install Ruby Gems - gives a zlib error

Whenever I try and install any ruby gem (trying to install rails), I get this error:

ERROR:  Loading command: update (LoadError)
    cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

I have tried everything I can think of; reinstalling ruby, trying different ruby versions, etc., but I keep getting this error.

I am currently using Ruby Version 2.3.1, and I am on mac os x 10.11 El Capitan. I am trying to install the rails gem on my system so that I can use it in all my projects.

If installing gems you used:

sudo gem install nameOftheGem

problem could be that you only use sudo if the stack was installed as root, so try the same as above without sudo.

Install zlib in your machine

rvm get head
rvm pkg remove
rvm requirements run force
rvm reinstall 1.9.3-p374

I guess that you missed zlib package if you are using rvm. https://rvm.io/packages/zlib/

Update:

I have two options, you can try one of them.

Option1:

Copy and paste this command to your console:

rvm pkg install zlib
rvm autolibs rvm_pkg

Option 2:

You need to install the zlib development headers.

xcode-select --install

Then reinstall your gem.
