As Nathan suggests, this does appear to be related to the fact that the latest versions of the sqlite3-ruby and hpricot gems don’t appear to have Windows versions. Here’s what to do when faced with this situation (note, the name of the gem is automatically wildcarded, so you can type just sql and get a … Read more
You can easily get a latitude and longitude using the google maps geocoding API. There are ruby implementations for the API like GeoKit. Once you have that you can use the timezone gem to easily get the timezone of a latitude and longitude. The gem makes it easy to do time conversions in your timezone … Read more
The gem install ffi fails due to the gem trying to build a bundled copy of libffi, which does not work due to assumptions that /usr/bin/env exists and too old libffi copy. However, you can build the ffi gem against the system libffi – install the packages: apt install clang make ruby-dev libffi-dev After that … Read more
The proper way to do this is outlined here. Since the gemspec is evaluated at package time, you need to do it in a native extension. Don’t worry, it’s not that scary since its still just Ruby code (not compiling C or anything). We are currently using this approach for some client tools for OpenShift … Read more

If you have XCode 4 or later you will need to open it and go to Preferences -> Downloads -> Components and install the Command Line tools as they aren’t installed by default. Couldn’t install Rails until this happened.
So based off what I can tell there is no easy command that can move the gemspec file from the default folder to the non-default folder. This is a good thing from what I can tell but here are the instructions on how to do this by hand. Find the location of the default spec. … Read more
In Ruby 1.9.3 only there is also: Gem.available?(‘somegem’) You can use regex expressions too. Handy if I want to allow ‘rcov’ and GitHub variants like ‘relevance-rcov’: Gem.available?(/-?rcov$/)
In my opinion, a full Engine is overkill for this task. You could instead just create a Railtie which includes your helpers into ActionView::Base when it initializes. # lib/my_gem/view_helpers.rb module MyGem module ViewHelpers def pre(text) content_tag :pre, text end def another_helper # super secret stuff end end end # lib/my_gem/railtie.rb require ‘my_gem/view_helpers’ module MyGem class … Read more
