问题 I have bash file which build gem files and launch my program: cd /src/stackify-api rm *.gem gem build stackify.gemspec gem install stackify-0.1.0.gem cd /src/stackify-classificator rm *.gem gem build stackify-classificator.gemspec gem install stackify-classificator-0.1.1.gem cd /src/bin ruby console-task.rb I use it in the docker container.

问题 I followed the steps here and installed the composite_primary_keys gem. When I try to require the gem in environment.rb at the very bottom of the file (after 'end') via require 'composite_primary_keys' I get this when starting the server "69125" => Booting Mongrel => Rails 2.3.4 application starting on http://127.0.0.1:3002 /Library/Ruby/Site/1.8/rubygems.rb:270:in `activate': You have a nil object when you didn't expect it!

问题 Could I simply copy the devise app and lib (and gem?) folders into my respective project folders and have them work just as if I was using the gem? I'd like to do this so that I can really see all the code, possibly do some customization, and also avoid some "cannot find" errors in my IDE. Is this a bad idea? If this is something that would work would I simply need to remove the gem and copy over the necessary files or would I need to "undo" things that the gem has done. Could this create

问题 So I haven't done too much craziness with add-ons via Compass for what I've been using it for. My primary use case was to leverage the color manipulation libraries and some of the conditional/looping structures to generate some different themes. Yesterday I did run an install for an ellipsis library and afterwards was given the following message when attempting to 'watch' my project... [Listen warning]: Missing dependency 'wdm' (version '~> 0.1')! Please run the following to satisfy the

问题 A lot of questions have been asked about gem support in Shoes, but none have answered where to put them.

问题 (Disclaimer: New to deploying Sinatra on Heroku.) I have seen http://www.sinatrarb.com/configuration.html and it tells me to set :environment, :production . My question is, how can I specify it to do: "when in Heroku, set environment as production, else stay in test/development." Also, even after putting the line set :environment, :production , I don't think it is working because when I try to rackup the app locally, it's still running (when I know (or I think I know) that it shouldn't
