bundler disappeared with ruby (solved, but what happened?)

Question

For the record, I already fixed my problem, but I'm trying to figure out what happened so it doesn't happen again.

I had been using Ruby earlier today and hadn't had problems. All of a sudden, I cant run anything.

In the past, I'd forget tobundle install and doing that that would make work out, but this time, I didn't even get that message. Instead I got this:

[ERROR] cannot load such file -- bundler/setup

And on trying to bundle install, I'd have this error:

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in `to_specs': Could not find 'bundler' (>= 0) among 16 total gem(s) (Gem::LoadError)
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:in `to_spec'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in `gem'
    from /usr/bin/bundle:22:in `<main>'

So bundler is not there? Where did it go?

I ended up having to do gem install bundler per this post. Then did bundle update and now everything works fine.

What may have happened?

Do you use RVM (or something similar)? It sounds like you were using a bundler from system or somewhere else in your path. I have seen that error when this happens.

Installing bundler for the current ruby should fix the problem -- which is what you did.
