I am trying to clone a repository from Github and I am on the step where I run "bundle install". However everytime I try to run this I get the following message:
An error occurred while installing eventmachine (1.0.3), and Bundler cannot
continue.
Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.
When I run "gem install eventmachine -v '1.0.3'" I get
Building native extensions. This could take a while...
ERROR: Error installing eventmachine:

I have tried a number of solutions (that have not worked) that I found online:
I've changed my ruby version to 2.1.5 in my .ruby-version file and gemfile.
I have also changed the eventmachine version in my gemfile.lock and gemfile to 1.0.4 and then also 1.0.7. After each change I then tried to run bundle install or gem install eventmachine. Which just produced the following:

What happened was that I didn't have xcode installed! once I downloaded I was able to run bundle install and update eventmachine

So I believe that this is a SSL certificat issue si I tried :
brew link --force openssl
logs :

Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
Do you guys have any ideas on going around this error ?

please any help would be appreciated.
This is your problem:
make "DESTDIR="
compiling binder.cpp
In file included from binder.cpp:20:0:
project.h:29:20: fatal error: iostream: No such file or directory
#include <iostream>
What's occurring is that the compiler cannot find project.h's include iostream. You could play around with installing it manually, link provided below.
https://github.com/eventmachine/eventmachine/wiki/Building-EventMachine
This link may help solve your problem.
C++ Hello World trouble on OSX10.8
Another potential quick fix is to install it manually and see if adding the header extension will solve your issue.
#include <iostream.h>
If you are using Mac OSX el captain, openssl headers are not installed by default therefore try installing openssl. If openssl is already installed try to relink using following command
brew link openssl --force
See this issue for more detail - https://github.com/eventmachine/eventmachine/issues/643

What am I getting wrong? Is it an issue with my RVM?
With some basic updates, I was able to get it to work.
bundle update
and then
bundle
installs the gem.
Thanks to https://github.com/celluloid/nio4r/issues/46
Another approach would be to install a later version of ruby with RVM and do bundle again. Both works
I'm trying to get set up with a somewhat outdated Rails app so I can try and update it a little but I can't seem to get bundle install working. It keeps telling me:

Anyone got a clue of what this might be?
I have installed ruby 2.0.0 with DevKit. Both in the 64 bit version.
The problem was solved with help from the thread that #GraemeMcLean mentions in the comments above ( Eventmachine gem install fail )
This was a weird workaround though, and the authors of the gem should really fix this.
