Cannot install gem 'therubyracer' in OS X Mavericks

Question

I am new to mac and tried to bundle install a cloned rails repo. I got an error while installing libv8 gem, googled and found a solution and did

brew install libv8
gem install libv8 -- --with-system-v8

Next I got struck at therebyracer gem, the full trace is as follows

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

I think this is a problem with Mavericks.

Answer 1

You may want to try what I summarized in this question: "gem install therubyracer -v '0.10.2'" on osx mavericks not installing

brew install apple-gcc42

sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 /usr/bin/gcc 
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2 /usr/bin/g++ 
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2 /usr/bin/cpp

brew uninstall v8 (only in case you installed it with brew)
gem install libv8
gem install therubyracer

Let me know if this works! I've been dealing with the same problem since the launch of Mavericks :)

Answer 2

Sorry, I don't know what fixed my problem. I was trying everything and it got fixed.

I installed gcc47 using macports, not homebrew.(it took nearly 2 days to install in my slow 512kbps connection)

Then I changed the version of therubyracer to '0.12.0'

I don't know which got my problem fixed.
