NAME

       bundle-pristine - Restores installed gems to their pristine condition

SYNOPSIS

       bundle pristine

DESCRIPTION

       pristine  restores  the installed gems in the bundle to their pristine condition using the
       local gem cache from RubyGems. For git gems, a forced checkout will be performed.

       For further explanation, bundle pristine ignores unpacked files on disk. In  other  words,
       this  command  utilizes  the  local  .gem cache or the gem´s git repository as if one were
       installing from scratch.

       Note: the Bundler gem cannot be restored to its original state  with  pristine.  One  also
       cannot  use  bundle  pristine on gems with a ´path´ option in the Gemfile, because bundler
       has no original copy it can restore from.

       When is it practical to use bundle pristine?

       It comes in handy when a developer is debugging a gem. bundle pristine is a great  way  to
       get rid of experimental changes to a gem that one may not want.

       Why use bundle pristine over gem pristine --all?

       Both  commands  are  very similar. For context: bundle pristine, without arguments, cleans
       all gems from the lockfile. Meanwhile, gem pristine --all cleans all  installed  gems  for
       that Ruby version.

       If  a  developer  forgets  which gems in their project they might have been debugging, the
       Rubygems gem pristine [GEMNAME] command may be inconvenient. One can avoid waiting for gem
       pristine --all, and instead run bundle pristine.
