Using the recommended ruby 2.1.0 and bundler 1.5 I got an error when running ‘bundle install …’. The error was something like this: ‘Bundler::GemNotFound: Could not find json-1.8.1.gem’.

I found an answer here: http://stackoverflow.com/questions/21095098/why-wont-bundler-install-json-gem

It seems that bundler 1.5 has a problem. The solution is to install bundler 1.5.1. When I did that the bundler found json and installed it.

My environment: Centos 6.4.

Hi Andrew,

thanks for your post. I added the bundler version requirement to every installation guide I know of :)
