Answer 1

This solution worked for me following Jakub Troszok's solution above with just a minor change

gem uninstall libv8
gem install therubyracer -v '0.12.1'
    Fetching: libv8-3.16.14.19-x86_64-darwin-18.gem (100%)

bundle install

Answer 2

It seems like this has been fixed upstream. What worked for me and @aurels and @Mike Causer and @Juanda was:

bundle update libv8

Answer 3

I did the following

gem install therubyracer

which now installs therubyracer 0.12.1 which installs the dependency libv8 (3.16.14.7 x86_64-darwin-14) which installed with no errors.

I did this using ruby 2.1.5 which I installed via:

CC=/usr/bin/gcc rbenv install 2.1.5

which I did after running brew upgrade ruby-builds.

After installing ruby 2.1.5, I also ran

gem upgrade --system

to get rubygems-update 2.4.5

Answer 4

gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.3' -- --with-system-v8

this is the only way it worked for me on 10.10 (ruby 2.1.2)

Or try gem install libv8 -v 'XX.XX.XX' -- --with-system-v8 adding the version of the gem :)

UPDATE for Mac OS Catalina:

brew tap homebrew/versions
brew install v8@3.15
brew link --force v8@3.15
gem install libv8 -v 'XX.XX.XX' -- --with-system-v8
gem install therubyracer

Answer 5

Updated answer for 2018.

I'm on High Sierra, on Homebrew 1.6.1

brew install v8-315

gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8@3.15/

Is what worked for me.

Answer 6

git clone https://github.com/cowboyd/libv8.git
cd libv8
bundle install
bundle exec rake clean build binary
gem install pkg/libv8-3.16.14.3-x86_64-darwin-12.gem #note that libv8 version may change, so tab through files in pkg/, also remember to use the one with version specified

then just bundle your project gems

this is the only way it worked for me on 10.10 (ruby 2.1.2)
