问题
I'm nearly crazy to install therubyracer. I know there're many people have the same problem with me, and I had also viewd these issues, however it's too complicated for me cause different situations have the different solutions. And in fact, there're have been not a good way to solve the problem. My problem is similar to this, and there have a discussion about it, however there're still have not a conclusion.
In spite of these, this is a good question asked by Chris S, but come not a good result.
① Here is some notes about my problem:
1.ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin15]
2.libv8 3.11.8.17 with native extensions
② OS X El Capitan, 10.11
③ Here is the error messages:
ERROR: Error installing therubyracer:

Help!
Well, firstly I'm so sorry to reedit the problem again, too busy no time to notice the comments your guys replied for me. And, here, I'm so appreciated that @Javid Jamae afford so great a way to me to solve the problem, although there're still some little matters to deal, but it's ok that we just need the errors to help us find the final answer. The follow is the console after I had try @Javid Jamae way,

It's seems the installation is ok! And then, I had uninstalled the therubyracer and libv8 with gem. However when it comes to install the therubyracer (I didn't point the version when install or in Gemfile, and the bundle remind me the version 0.12.2 is need), there're comes the error:

.................. (the follow error messages are similar to above)
Well, I'm wonder it's still the problem of the libv8! At first, I think it's maybe the problem of the version of therubyracer, so I had make a try to install the version 0.12.0, unfortunately, there're the same errors. There're something strange, I mean the libv8 is installed with the therubyracer in my case (see that from the error messages), but you're different with me. As your suggestion marked you install the libv8 after you had installed the therubyracer, why they're different? Maybe it's relate to my ruby environment settings, here I posted my Gemfile configuration:

I had the sam problem in OSX El Capitan. The steps I used to get over this were
First check if V8 is installed or not. I used brew to install it.
brew install homebrew/versions/v8-315
Try uninstalling libv8, therubyracer gems if some instance exists.
gem uninstall -a libv8
gem uninstall -a therubyracer
Then install the libv8 gem.
gem install libv8 -v '<<VERSION>>' -- --with-system-v8
Then install the therubyracer gem.
gem install therubyracer -v '<<VERSION>>' -- --with-v8-dir=$(brew --prefix v8-315)

This worked for me:

$ gem uninstall therubyracer
$ gem uninstall libv8
$ gem install therubyracer -v '0.12.0'

I had the same problem, updating therubyracer to the latest version solved the issue.
Try:
bundle update therubyracer
If you also have issues with libv8 then try:
bundle update libv8
