Unable to install on OS X 10.11.4 with Ruby 2.2.4

[Geesu]

I'm just simply trying to run gem install therubyracer and I'm receiving the following errors:

I have tried the following as well, but it is the same error:

brew tap homebrew/versions
brew install v8-315
brew link --force v8-315
gem install libv8 -- --with-system-v8
gem install therubyracer```

I have the same problem. I tried number of things, including reinstalling all rubies, as well as different combination of libv8 and rubyracer as it seems that interface has changed. However I was not succesfull figuring this out.

[Geesu]

What's odd is I was able to get it working with the above on MY macbook pro, and I have no idea why. This was after spending 2 hours trying to get it work on my co-worker's mac, which I still haven't been able to complete (hence the issue).

[desireco]

Same here. It works on my laptop, on desktop I just can't make it work and I was hoping during weekend to use bigger screen to work through some stuff. Both are with updated software. So I don't know. Wish I know where else to look.

[EricBoersma]

Also seeing this problem. Fresh install of El Capitan, can't install therubyracer.

[EricBoersma]

For those struggling with this, I was able to follow the steps included in the accepted answer on This StackOverflow question. Specifically the parts about using the 4.2.2 GCC for building libv8 in the bundler config. That workaround has worked for me.

[Geesu]

Shux, I was really hoping that would do it @EricBoersma but I receive this error: https://gist.github.com/Geesu/5e93aec94ed4962dcbc85a8c509784fc

[im-kulikov]

brew tap homebrew/versions
brew install v8-315
brew link --force v8-315
gem install libv8 -- --with-system-v8
gem install therubyracer

solved my problem, thanx @Geesu

[Southern]

I was able to use this to finally get it working:

brew install v8-315
bundle config --local build.libv8 --with-system-v8
bundle config --local build.therubyracer --with-v8-dir=/usr/local/opt/v8-315
bundle install

[desireco]

Strangely, this solved my problem. Thank you. I kind of not sure why this would work and normal ways wouldn't. But happy it does work.

[Southern]

Yeah. It took me 2 days to figure this out. Tried all of the combinations in this issue with no luck, some from StackOverflow, and finally hit this one. Glad it helped.

[desireco]

Thank you. I think this solves it.

[avatsaev]

@im-kulikov yes this worked, thanks

[Geesu]

Yes that did it!

[ronnietaylor]

#issuecomment-209169869 worked for me. Thanks!

[KudosX]

thanks southern!!
#issuecomment-209169869 worked for me with rails 5.0.0.beta3.
that was painful finding a solution.
I have no idea how you figured that one out but, sure glad you did!

[Southern]

It was pure luck. I just started working with Ruby/Rails like 3 days ago, and most of that time was spent looking for this solution.

Glad it's working for everyone though.

[haaayden]

Thank you!

There has been a new release of libv8 that should address most OS X install issues. Closing for now.
