rake bootstrap failing with ruby 2.2.0

[andreamazz]

Hi all.
While setting up Rainforest on a fresh install with ruby 2.2.0 I noticed that json 1.7.7 fails, as stated here.
Using ruby 2.1.2 fixes the issue, maybe the README should point this out, what do you think?

I'm pretty sure we have a .ruby_version?

[andreamazz]

This repo doesn't seem to have one.

Ah yeah json 1.7.7 doesn't compile on 2.2, I've needed to manually patch it to work. I just recommend using system ruby for CocoaPods development, honestly.

I just ran into this same issue; perhaps it would be a good idea to specify which Ruby version(s) should be used when running rake bootstrap in the README?

Switching to ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0] worked for me, with the exception of this failure:

I fixed the above issue by commenting out Line 17 (and the corresponding end) in Molinillo's Gemfile:

install_if RUBY_VERSION >= '2.0.0' do

Not sure what the issue causing that is though.

[segiddins]

install_if is a bundler 1.10 feature
