rubygems

问题 Is it possible to search for all gems that rely on a certain rubygem? For example, I'd like to ask for all gems in gemcutter that rely on the test-unit gem. Background : I'm looking to see how other gems handle the issue mentioned here. 回答1: I had the same problem, and found that some of the other suggestions for this question are now defunct. I came up with a 2-step solution that worked for me. The following unix-y script will tell you all the gems your gems depend on: gem list | egrep '^.*[

问题 I read "Relationships between Rubygems, Bundler, and RVM" before asking it again. Well, there are many questions like this, but people who answered say they work with Rubygems, RVM and Bundler, and they have not explained how each of these work in isolation. I am really confused with how the three work in isolation when we are installing gems. Please do not tell me how you work, which will help me, but I won't learn what is happening when we play with them. My confusion can be broken down

问题 I just upgraded to Rails 3 and had a bit of a mess with MacPorts, gems and databases to sort out. I threw out all the gems and installed them fresh. Everything seems to be OK except for the requirement of the pg gem. After creating a new Rails 3 project, prepared for PostgreSQL, the server would not start, complaining about the missing pg gem. Doing bundle install , it chugged along for a while and, of course, fails on the pg gem. Installing pg (0.10.0) with native extensions /Library/Ruby

问题 I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link. I think it's an update to Ruby, but RVM is having trouble installing alternate versions of ruby as well. Heres the full post: $ sudo gem install jekyll ERROR: Error installing jekyll: ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework

问题 I'm going to start with the usual noob line, "I'm new to rails". Oh, and I'm running Mac OSX 10.6.4 I've been following a bunch of guides to get set up, specifically these two here and here. The guides are great, the reason I'm using the second one is because of RVM and the reason I'm using the first is for MYSQL. Anyway, when I started, I wasn't following the directions completely and so after I installed RVM, for some reason I installed rails with sudo gem install rails -v 2.3.8 because
