undefined method file=' for #<Pry::History using pry v0.13

Using the latest version of guard and pry (just released) in a Rails application, you'll get this error:

$ bundle exec guard

There's a PR that fixes this already submitted #955

In the meantime, you can lock your version of pry to v0.12 in your Gemfile

  gem 'pry', '< 0.13' # or maybe just '0.12.2'

These versions work:

 * guard (2.16.1)
 * pry (0.12.2)
 * pry-byebug (3.8.0)
 * pry-rails (0.3.9)

while this set will now

 * guard (2.16.1)
 * pry (0.13)
 * pry-byebug (3.9.0)
 * pry-rails (0.3.9)

I think this is a duplicate of #953. Thanks for the issue anyway!
