问题 I tried to push a ruby gem for the first time while on a terrible internet connection. When I first tried to push, I was able to sign in and then it hung there for probably about 10 minutes with no sign of progress so I decided to just kill it and hit ctrl+c , which may have been a poor decision.

问题 I have been trying to run my ruby application on the server recently and I keep coming across this error: Could not find rake-10.0.4 in any of the sources (Bundler::GemNotFound) I am running Rails 3.2.12 and Ruby 1.9.3p392. Until now I have not had any problems when accessing the server, and this is the first time I have come across this error.

问题 I am trying to use the instructions here to install a pre-released version of a gem with bundler. The "bundle install" output lists the gem as getting installed, but "gem list" fails to find it. My Gemfile: source :gemcutter gem 'sinatra', '1.1.0', :git => 'http://github.com/sinatra/sinatra.git' gem 'RedCloth', '4.2.3' Here is a gist with the rest of my sample code. Has anyone gotten this scenario to work? NOTE: I am also using RVM (on OS X). bundle show does list the gem (and dependencies)

问题 This is purely an experiment, but I'm wondering if it's possible to get a list of the require 'd gems at runtime via some kind of metaprogramming. For example, say I have: require 'rubygems' require 'sinatra' require 'nokogiri' # don't know what to do here How can I print out the following at runtime? this app needs rubygems, sinatra, nokogiri 回答1: You can't do this exactly, because requiring one file may require others, and Ruby can't tell the difference between the file that you required

问题 Autotest increases the speed at which tests run by running only the changed tests.

If you happen to be on OSX, there are also instructions to utilize

If I do: bundle exec jekyll serve All work fine ( _site folder contains necessary files and server is running), but if I use the following command: jekyll build -d /var/www/budka/data/www/blog I get the error: Dependency Error: Yikes! It looks like you don't have jekyll-paginate or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is:
