Fix therubyracer/libv8 (0.12.1) installation on Mavericks

Tags:

OK, I’m at the end of my tether with this. There are a few similar questions but they all refer to therubyracer 0.10, and they mostly conclude that the problem can be fixed by upgrading to 0.12.

I’m having similar problems, but when I use 0.12.

Similar questions

  • Installing libv8 gem on Mavericks
  • How to fix libv8 error from Gemfile on Mavericks?

I’m having problems using ‘standard’ (xcode?) gcc, and both apple-gcc42 and gcc from homebrew. I’ve tried both --with-system-v8 and --without-system-v8, and again, no dice.

Here’s some logs:

OK. So to fix the issues with therubyracer 0.10, some people recommend brew installing v8, then telling rubygems to use system v8. Let’s see what happens!

I was able to proceed with ruby racer after rm Gemfile.lock Perhaps try this, which is easier than the RVM nuke option.

beforehand: I installed v8 via brew install v8, and then did gem install libv8 -v '3.16.14.3' -- --with-system-v8

and I am running 10.10 Yosemite

I was able to get things going again by running gem install libv8 -v '3.16.14.3' -- --with-system-v8.

OK, so this is now sorted.

For future people with the same problem, I was suffering from having ruby built against a previous installation of OS X.

Fixed by completely nuking rvm and starting from scratch, though I imagine you could just uninstall/reinstall the offending ruby.

More details on how the problem was solved here:

Same issue with OSX 10.9.3, ruby 2.1.3 and every version of therubyracer.

Now i'm letting execjs (uglifier gem dependencie) take care of it.

ExecJS lets you run JavaScript code from Ruby. It automatically picks the best runtime available to evaluate your JavaScript program, then returns the result to you as a Ruby object.

OSX users

"Apple JavaScriptCore" comes as default for JS runtime on OSX. Just installing execjs will solve the problem.

Linux users

Install node.js. Execjs gem will automatically choose node.js as js runtime.

sudo apt-get install nodejs
