问题 I am trying to debug a gem that's used by a Rails app. I cloned the Gem locally to go prying around (and also allows me to do nice things such as git bisect , etc.) # Gemfile gem "active_admin", path: "~/dev-forks/active_admin" However, I am often stuck with adding Pry to a Gemfile somewhere to be able to use it, or calling require "pry" live in the code even though I don't want it in there. For example, I will sometimes forget about it, fix the bug, and then commit to the project with Pry in

问题 I have a sinatra application and packaged that as a gem. Its file-layout looks roughly like this: ├── bin │ └── tubemp ├── lib │ └── tubemp.rb ├── Gemfile └── tubemp.gemspec I can install and run it just fine. Calling ruby lib/tubemp.rb fires the app too, because Sinatra made it self-starting. tubemp.rb : class Tubemp < Sinatra::Application get '/' do erb :index, :locals => { :title => "YouTube embeds without third party trackers." } end end The binary is really simple too. bin/tubemp : #!

I've re-installed active model and restarted my terminal.

问题 I have a Padrino App called Gusy that specifies (Sequel) Models like # gusy/models/seminar.rb class Seminar < Sequel::Model # hopefully irrelevant stuff defined here end I want to access this Model from either a second gem, or a script in bin/ .

I can successfullly see the Gusy namespace (and e.g. print the apps Version Gusy::VERSION ) if interactively exploring with bundle

问题 I have a Sinatra app using Postgres via Activerecord. I'm using RVM on a Mac and a number of gems including: activerecord activesupport When I run the server (thin), I get an error: Could not load 'active_record/connection_adapters/postgresql_adapter'.
