therubyracer install error

Question

As you can see below, libv8 installs fine, but therubyracer doesn\'t. I\'m using Mac 10.7.4.

~/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1> gem install lib         


        

Answer 1

@Haegin's answer in https://github.com/cowboyd/libv8/issues/205

brew uninstall v8
brew install v8-315
gem uninstall -a libv8
gem uninstall -a therubyracer
gem install libv8 -v '3.16.14.17' -- --with-system-v8
gem install therubyracer -v '0.12.2' -- --with-v8-dir=$(brew --prefix v8-315)

Answer 2

For Linux:

The code below is of course correct

$ gem uninstall libv8

$ gem install therubyracer

But sometimes it does't help because you haven't program make. AT FIRST you need install make. To do this, run:

sudo apt-get install build-essential

And only after that:

gem install therubyracer

Answer 3

The solution that worked for me was putting these steps together on 10.7.4

export CC=gcc-4.2

sudo ln /usr/bin/gcc /usr/bin/gcc-4.2

gem uninstall libv8
gem install therubyracer

Answer 4

For an older project I had to used the 0.10.1 version of rubyracer on mavericks (bootstrap depends on it)

So I had to use an older version of gcc

1. edit your .zshrc or .bashrc

   export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
   export CXX=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2
   export CPP=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2
   

2. be sure that you have uninstalled all older versions of libv8

   gem uninstall libv8
   

3. install your version of therubyracer

   gem install therubyracer -v=0.10.1
   

Answer 5

On OS X 10.7 I actually found that the "Command Line Tools" package wasn't enough, I had to install the full-blown XCode package, then gem install worked.

Answer 6

I had this same problem when I upgraded from OSX Mountain Lion to OSX Mavericks.

Upgrading from ruby-1.8.7-p354 to ruby-1.8.7-375 did the trick for me. If you are on ruby-1.93-p125, you may want to try upgrading to 1.9.3-rc1 (which is above p484 already)

libv8 (3.16.14.3-x86_64-darwin-13) and the therubyracer (0.12.0) gems installed without problem.

assuming you use rbenv:

rbenv install 1.9.3-rc1
rbenv rehash
rbenv shell 1.9.3-rc1
bundle install
