Installing therubyracer on Mac OS and Ruby 2.3.0

[justin808]

If you have the below problem, the solution that worked for me on April 3, 2016 can be found here:

http://stackoverflow.com/a/36388150/1009332

brew tap homebrew/versions
brew install v8-315

gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install

Errors that this fixes:

Thanks for this. Saved me a headache.

[bhushangahire]

Thanks a lot. I tried this before but somehow v8-315 was not downloading. I think they relinked the same :)

[adamjgrant]

Worked for me as well although I had to change the gem install line to

gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8@3.15

Thanks!

MacOS Mojave
install therubyracer version '0.12.2'

brew update
brew install v8
gem install libv8 -v '3.16.14.15' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=#{libv8_path}

on my computer, libv8_path is /usr/local/Cellar/v8/7.2.502.25

MacOS Mojave
install therubyracer version '0.12.2'

brew update
brew install v8
gem install libv8 -v '3.16.14.15' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=#{libv8_path}

on my computer, libv8_path is /usr/local/Cellar/v8/7.2.502.25

In my case I had to use /usr/local/Cellar/v8/7.3.492.25/libexec as libv8_path

I still seem to be having this issue even after following all of the steps above:

 gem install therubyracer -- --with-v8-dir=/usr/local/Cellar/v8/7.3.492.27

yields:

I also tried with the libexec path as suggested by the previous comment and it yielded the same result.

This answer https://stackoverflow.com/a/25757171/6186921 worked for me. MacOS Mojave.

gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.15' -- --with-system-v8

[ssjod]

Using homebrew's directory of v8 for --with-v8-dir=/usr/local/Cellar/v8@3.15/3.15.11.18_1, instead of /usr/local/opt/v8-315, is what worked for me, in coding addicted's answer.

This is visible in the Summary of the brew install command, brew install v8-315.

[guillaumebihet]

Same as previous comment, with specifying in addition the required version, as such:
gem install therubyracer -v '0.12.2' -- --with-v8-dir=/usr/local/Cellar/v8@3.15/3.15.11.18_1

[hussainakram]

I have tried all above mentioned but nothing did work. But updating mini_racer did work in my case:

bundle update mini_racer

It updates the version of libv8 from 6.7.288.46.1 to 7.3.492.27.1 which solves the issue.

In my case, bundle was stuck at this point for more than 30 mins even after multiple tries

Also raised the PR: #466

Worked for me as well although I had to change the gem install line to

gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8@3.15

Thanks!

This works for me, thanks!
