“gem install therubyracer -v '0.10.2'” on osx mavericks not installing

Question

Trying to install therubyracer on mavericks using \"gem install therubyracer -v \'0.10.2\'\" but i am getting the following error:

/Users/dennischen/.rvm/rub         


        

Answer 1

I had the same problem, this works for me:

therubyracer (0.10.2) & libv8 (3.3.10.4)

First of all:

• brew install apple-gcc42
• you must link all the binary files of the compilers (gcc, cpp, g++) to /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/<compiler>

After, you could try this:

• brew install v8
• gem install libv8 -v '3.3.10.4' -- --with-system-v8
• gem install therubyracer -v 'therubyracer' or bundle install into the directory of the rails project.

Answer 2

I found a workaround that worked without installing apple-gcc42.

This will work if the error message you're getting looks like this:

clang: error: no such file or directory: '/Users/mscottford/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/libv8-3.3.10.4/lib/libv8/build/v8/libv8.a'

Then you should be able to do the following:

brew install v8
bundle install 
# after failing create link from brew installed v8 to error location
ln -s /usr/local/Cellar/v8/3.21.17/lib/libv8_base.x64.a /Users/mscottford/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/libv8-3.3.10.4/lib/libv8/build/v8/libv8.a
bundle install

Answer 3

I had a nearly identical error when trying to install therubyracer 0.12.0 to get it to work with libv8. This worked for me:

$ brew upgrade gcc

$ gem uninstall therubyracer

$ gem uninstall libv8

$ gem install therubyracer -v '0.12.0'
Fetching: therubyracer-0.12.0.gem (100%)
Building native extensions.  This could take a while...
Successfully installed therubyracer-0.12.0
1 gem installed

$ gem install libv8 -v '3.16.14.3' -- --with-system-v8
Fetching: libv8-3.16.14.3.gem (100%)
Building native extensions with: '--with-system-v8'
This could take a while...
Successfully installed libv8-3.16.14.3
1 gem installed

Answer 4

So I finally got it working after some struggling... thanks to Simon and Alvaro.

I have one thing to add though, using the flag --with-system-v8 did not work for me... So i removed my system v8 with

brew uninstall v8

And the run

gem install libv8

If you have already run gem install libv8 with the system v8 flag be sure to uninstall that gem version (do it by running gem uninstall libv8). The important thing is that you shouldn't use the one provided by brew, it does not seem to work in Mavericks (it gets installed well and bundler will report that your bundle is complete, but your app will fail when it tries to use v8).

To summarize the answer, doing the following worked for me:

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
gem install libv8
gem install therubyracer

I manage to install therubyracer 0.12 and libv8 3.16.14.3 on ruby 2.0.0p353 and os x 10.9

libv8 requires gcc42

brew install v8
brew install apple-gcc42
sudo ln -sf /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 /usr/bin/gcc
sudo ln -sf /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2 /usr/bin/g++
sudo ln -sf /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2 /usr/bin/cpp
gem install libv8

therubyracer requires later gcc

brew install gcc49
sudo ln -sf /usr/local/Cellar/gcc49/4.9-20131110/bin/gcc-4.9 /usr/bin/gcc
sudo ln -sf /usr/local/Cellar/gcc49/4.9-20131110/bin/g++-4.9 /usr/bin/g++
sudo ln -sf /usr/local/Cellar/gcc49/4.9-20131110/bin/cpp-4.9 /usr/bin/cpp

Gemfile

gem 'therubyracer', :require => 'v8', :platforms => :ruby

use bundle instead of gem install therubyracer

I just had the same problem and one solution is currently to use apple-gcc42 instead of clang to compile both gems :

brew install apple-gcc42

And then you have the choice between doing some symlinks in /usr/bin for {gcc,g++,c++} binaries :

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

In fact g++ should be enough.

Or...you could export CC/CXX/CPP environment variables with paths corresponding to the binaries created by homebrew. That's surely a cleaner workaround.

A third solution is to download Xcode 4.6.3 and install it in the Applications folder. Then, enter in the terminal:

sudo xcode-select --switch /Applications/Xcode4.6.3.app/Contents/Developer
gem install therubyracer

Once the gem has been installed you can switch back to Xcode 5.0 :

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
