问题 I have followed minimal examples using the rouge gem here (i.e. the documentation), as well as here and here. Everything working, except that line breaks in the code aren't appearing. To be explicit, code like this def plus_two(x) x + 2 end has the colours highlighted correctly, but is rendered across one line, like so def plus_two(x) x + 2 end How can I make it render with the line breaks (just as in the code file) 回答1: Change require 'rouge' source = "def plus_two(x)\n x + 2\nend" formatter

问题 I'm developing two gem: Runel and Runic. Runel depends on Runic. But then how do I get Runic to load up to run Runel tests (and bundle install). I need Runic in the Runel tests because some of Runel's classes extend from Runic's classes. And I want to test it (try it out) as the whole thing (Runel is a VM, Runic is the base for it). 回答1: If Runel depends on Runic, then the tests of Runic should use Runel. That is, Runic provides a service and this service should be tested as an independent

问题 Currently I am using rails 2.3.10, I want to update my rails version to version 3. What's the command to update rails? 回答1: So, the basic command would be: gem update rails But, upgrading from 2.3.x to 3.x isn't a trivial task... you should really read up a little more on it before you do so. 回答2: Ryan Bates shows you how to do it here. The Rails version you are using are completely different so you will have to upgrade Rails and then use this plugin to help upgrade your application unless

问题 I've deployed a new server that has the exact same version of JRuby (1.7.22), Java (openjdk-7-jre-headless 7u51), and bundler as the other servers. Both servers are running Ubuntu 14.04, but the new one has some newer packages. I deployed the same version of the project using Capistrano to the new server.
