rubygems

问题 I've noticed that when generating a new rails project, the Gemfile now defaults to: source 'https://rubygems.org' instead of source 'http://rubygems.org' and now bundle install fails for me. When it attempts to run, I get: /Users/<my user name>/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/http.rb:799: [BUG] Segmentation fault If I manually change the Gemfile to http , then bundle install performs fine. Is there an error with my setup (I've replicated this on two different boxes), or is there

问题 When a user clicks, for example, "Take a Picture" how can we prepopulate the create.html.erb form with attributes specifically set for that featured challenge, like do for 12 days and do on Tue, Thu ? I am using the reform gem. #challenges_controller def new @challenge = Challenge.new respond_modal_with @challenge, location: root_path end #challenges/new.html.erb <%= simple_form_for(@challenge, html: { data: { modal: true } }) do |f| %> <%= f.text_field :action, placeholder: 'Enter a Custom

问题 Is there a gem or something to parse strings like "4h 30m" "1d 4h" -- sort of like the estimates in JIRA or task planners, maybe, with internationalization? 回答1: Posting a 2nd answer, as chronic (which my original answer suggested) doesn't give you timespans but timestamps. Here's my go on a parser. class TimeParser TOKENS = { "m" => (60), "h" => (60 * 60), "d" => (60 * 60 * 24) } attr_reader :time def initialize(input) @input = input @time = 0 parse end def parse @input.scan(/(\d+)(\w)/)

问题 do you know an alternative to jrails? It's more or less outdated (uses jQuery 1.5 - now 1.7 is the current release). Does anybody know an alternative? Thanks EDIT: I know how to build the rails helper with jquery allone - but I like the rails helpers, so I dont want to use jquery allone (without jrails) 回答1: Right now there's no real alternative. However, you can install jRails then upgrade the jQuery installation simply replacing the javascript files (except jrails.js) in the javascripts

问题 Can't find the 'libpq-fe.h header ** extconf.rb failed ** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. Where do I find the mkmf.log file? 回答1: The mkmf.log file can be found under the gem's installation directory. rvm If you are using RVM, then look for a directory similar to ~/.rvm/gems/ruby-1.9.3-p194/gems/some-cool-gem-name/ext/mkmf.log You can list all the mkmf.log files available with this

问题 I installed Ruby 1.9.2 using one click installer to c:\ruby192 It doesn't set any path, so I set it to include c:\ruby192 at the very beginning of the path. But when it error on something (for Rails 3.0), the path says: [Error message] c:/ruby192/lib/ruby/gems/1.9.1/gems/railties-3.0.0/lib/rails/commands.rb why is it 1.9.1 gems path for Ruby 1.9.2? 回答1: From a little FAQ chapter to the release: The standard library is installed in /usr/local/lib/ruby/1.9.1 This version number is "library

问题 How do I find out if a particular gem is compatible with a certain Ruby version or not? I want to upgrade the Ruby version of an application I am working on, But I did not see an authentic way of knowing which Ruby version is supported by a particular gem. I found the *.gemspec of the gem, which often contains a configuration saying config.required_ruby_version ... , but I noticed not all the gems contain a gemspec file. I noticed I have a few gems on my system, ActiveRecord for example,
