问题 What does that mean? In the instructions for a project, it said to "freeze the Rails gems". Is that different from freezing the Rails version? What's freezing about? 回答1: If one of the authors of a gem you use introduce a new version of the gem, there is a possibility the new version introduces backwards incompatible changes that would break your code. Freezing a gem puts it into the vendor folder of your application, and it will not be automatically updated on its own. Rails will use this

问题 Completely new to Ruby on Rails. My environment is Windows 2008 R2, and I just use the RailsInstaller to set it up. I was given a website, so I placed it under C:\Sites. I followed the guide, and installed rails, as you can see the version down there in the code. Then I ran "rails server" to try to start the service, but I was given error message about "therubyracer-heroku-0.8.1.pre3 not installed, so I did a gem install and bundle install after that. Then therubyracer-heroku threw bunch of

问题 I have a project (tracks) that ships its gems under vendor/gems . Some of these gems are no longer available trough rubygems, so a rake gems:install fails. I want rubygems to load gems from both the rvm-gem-dirs ( /usr/local/rvm/gems/ruby-1.8.7-p334@tracks, /usr/local/rvm/gems/ruby-1.8.7-p334@global ) and from the vendor/gems . How can I add such a dir to the rubygems load path? Is that possible at all? 回答1: Add the vendor/gems directory to the GEM_PATH environment variable. GEM_PATH=$GEM

问题 I copied the application from production and did bundle install to install all the missing gems that are in production version and not on my local machine.

问题 TL;DR: Below is a tragic story of a how I lost about 8 hours of my life because different gems were looking for different versions of openssl that weren't there. In the course of coming here to beg for help and writing up everything I tried I've managed to implement the hackiest fix imaginable, at which point I have to get back on with actual work. But this solution seems totally inadequate for reasons I outline below. So I'm asking: Is there a proper way of specifying system dependencies for
