"bundle install" fails on Mac OS X

[carnesen]

I encountered some issues trying to build the site on Mac OS X. "bundle install" completes successfully with Ruby 2.1.2, but fails with 2.0.0, which is what the site uses currently. I'm moving forward by using a Linux VM for development, but wanted to make a note here of the failure.

Installing therubyracer 0.12.1 with native extensions

Not having a Mac, I don't have any advice for this issue. I'm currently waiting for Jekyll 3.0 to be released before starting a general upgrade of all our gems to the latest released versions, so hopefully that will resolve this issue.

For now, I'm going to tag this as Help Needed.

@carnesen Maybe you can experiment with workarounds from StackOverflow.

Ideally there would a be a clean solution not involving any extra steps than running "bundle install", but according to what I read this may prove difficult. Unfortunately I am also not a Mac OS X user so I am not able to investigate this on my side either. Thanks for reporting the issue!

Thanks to both of you for your replies. I didn't want to spend too much
more time on it because everything "just worked" with Ruby >2.1.2, which I
figured we'd upgrade to at some point in the not-too-distant future. I'm
also still on chapter 1 of Ruby, gems, and all that jazz, so not so good at
debugging such issues. As far as I can tell, besides that failure resolved
by Ruby >2.1.2, the only difference in the developer setup instructions on
Mac is that instead of using apt-get to "Install binary libraries and
tools", one must "Install the Xcode command-line tools", which is super
easy; any time you try to run a command included in the tools (e.g.
"make"), it prompts you to install the tools if you haven't already.

For now I like the workaround of just running the build on an Ubuntu
virtual machine. The combination of Vagrant
and VirtualBox makes that pretty easy to set
up, under 15 minutes. I could document those VM setup steps if we
eventually decide that's the best way to support Mac-based bitcoin.org
development.
