问题 I'm trying to replace a bad version of my gem on rubygems.com, but yanking fails. You can see at https://rubygems.org/gems/v2gpti that the gem does exist at v0.2.

问题 Is there a way to tell Bundler to install a particular .gem file I have lying around? I have a compiled version of ParseTree that I must use (damn you, Windows!), but didn't want to expand the gem file in order to add a :path => '...' attribute to the 'gem' requirement. 回答1: You could also package your gems with bundle package , which puts all of your gems in the vendor/cache directory of your project.

问题 To provide some background - I've just downloaded a Git Repo from GitHub, for a friends app and I am attempting to launch it from my Mac ('rails s').
