Unable to install therubyracer on clean install of Yosemite and clean version of ruby

Question

There are many people with similar issues and I've been one of them in the past on other machines and none of the solutions out there appear to work -- I also appear to have different error than others who have similar problems:

Building native extensions.  This could take a while...
ERROR:  Error installing therubyracer:

Gem files will remain installed in /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/gems/therubyracer-0.12.2 for inspection.
Results logged to /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/extensions/x86_64-darwin-14/2.0.0/therubyracer-0.12.2/gem_make.out

When running:

gem install therubyracer -v '0.12.2'

or simply

bundle install

with therubyracer included in my gemfile.

I'm running Yosemite 10.10.3, Ruby 2.0.0-p353, I have uninstalled everything and tried the gem install libv8 -- --with-system-v8 solution that comes up frequently with these kind of problems, but have found no resolution.

Answer 1

Creating a temporary file '__debug' solved this issue for me.

Run this command in terminal:

echo '#define _LIBCPP_ASSERT(x, m) ((void)0)' | sudo tee -a /Library/Developer/CommandLineTools/usr/include/c++/v1/__debug > /dev/null

Answer 2

I was able to solve this by re-installing Command Line Tools for XCode 6.2 (instead of those for XCode 6.3).
