Using rbenv for a Ruby 2.3.0 environment on OS X 10.11.1 I am unable to get therubyracer Gem to install when using 'bundle'.
This is successful:
> gem install therubyracer
Building native extensions. This could take a while...

In my Gemfile:
gem 'therubyracer', '0.12.2', platforms: :ruby
This fails:

To see why this extension failed to compile, please check the mkmf.log which can be found here:
/Users/jsidlosky/code/sentons/websocket-rails-demo/.bundle/extensions/x86_64-darwin-15/2.3.0-static/therubyracer-0.12.2/mkmf.log
The mkmf.log file's error is:

Some things I've tried:
From: How to install therubyracer gem on 10.10 Yosemite?
git clone https://github.com/cowboyd/libv8.git
cd libv8
bundle install
bundle exec rake clean build binary
gem install pkg/libv8-3.16.14.13.gem
From: Bundle install tries to use cache file
Adding to ~/.bundle/config
BUNDLE_PATH: .bundle
BUNDLE_DISABLE_SHARED_GEMS: "1"
I also tried this:
bundle config build.libv8 --with-system-v8
I've now spent well over 5 hours trying other random ideas from various StackOverflow questions and other sites. So far, nothing gets me a working therubyracer inside "bundle" even though "gem install therubyracer" works just perfectly.
I will be very grateful for any pointers or solutions.
It appears from the comment from: github.com/cowboyd/therubyracer/issues/359
"I wasn't able to get any of the above solutions to work (or rather, everything I could get to work would have required the rest of my team to rebundle). After switching from rbenv to RVM, however, bundle install ran without a hitch."
I tried switching from rbenv to RVM and it worked perfectly. I can now 'bundle' and therubyracer gem installs perfectly.
