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

You can use the Libv8 from the brew instead of the one from gem. You can do that by following commands:

$ gem uninstall libv8
$ brew install v8
$ gem install therubyracer

Answer 2

I've had the exact same issue just till now.

This link saved me.

to sum up, you need to do this:

$ gem uninstall libv8
$ gem install therubyracer

before i fixed this issue, i had v8 installed in my mac. i don't know if this helped, since it seems have sth to do with js interpreter, I thought it might help.

Answer 4

Mac 10.10.5, Ruby 2.1.0 this worked for me:

gem uninstall libv8
gem uninstall therubyracer

brew upgrade gcc
brew install v8

bundle config --local build.libv8 --with-cxx=/usr/local/bin/gcc-6
gem install libv8 -v '3.16.14.17' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install # worked !

Answer 5

On Mavericks, you just need to update to therubyracer 0.12.0

Answer 6

On Mountain Lion 10.8, it doesn't come preinstalled with a C compiler. You'll need to download and install the 'command line tools' package from Apple themselves, and then run which gcc to confirm it is installed. Everything should run fine from there on in.
