问题 There already a lot of topics about it. But I'm stuck I configured ssh with succes! Now I like to configure the portforwarding for connection with TOAD. I used this tut: https://blog.openshift.com/getting-started-with-port-forwarding-on-openshift/ Now when I try rhc port-forward -a php I get this error Could not parse PKey: no start line I founded this: http://blog.skypayjm.com/2015/02/accessing-remote-openshifts-database.html I tried to downgrade ssh, but it didn't change anything.

问题 I created a simple Gem for Ruby on Rails; the idea is that it provides some code/views for common actions (index/show/etc.) that I use in several of my applications. I would like to "DRY it up" in a Gem. Creating the Concern went without problems, however, I can't quite seem to manage to render a view in my application. For example, in my lib/rails_default_actions/rails_default_actions.rb I do: module RailsDefaultActions module DefaultActions extend ActiveSupport::Concern respond_to do

问题 I wanted to make a fresh Ruby app, so I decided to use bundle gem foo to do it. This gave me the whole: lib/ foo/ version.rb foo.rb Gemfile Rakefile foo.gemspec README.md structure. Now when I run ruby foo.rb , I get: `require': cannot load such file -- foo/version (LoadError) foo.rb is just the default: require 'foo/version' module Foo end Can gems not be ran on their own? I hope I don't have to include my gem into a sample app just to test it out? 回答1: You need to run bundle exec ruby foo

问题 I am trying to install ruby on windows 7 behind a proxy. I have looked at various forums and have set (i think) the http_proxy successfully (see below) SET HTTP_PROXY=http:username:password@http://proxyhere.com:8080 however, i now get the following error trying to install a gem: SocketError: getaddrinfo: No such host is known. Any ideas? 回答1: The HTTP_PROXY syntax needs to be URI: SET HTTP_PROXY=scheme://user:pass@host:port/path scheme could be http or https and on some cases path could be

问题 I have this in the Gemfile: gem 'mysql2' But when I run bundle update , I get this error message: An error occurred while installing mysql2 (0.3.16), and Bundler cannot continue. Make sure that `gem install mysql2 -v '0.3.16'` succeeds before bundling. I've tried to move this into the production section, like this: group :production do gem 'mysql2' end But after running bundle update , the result is the same. This section is processed only in the production mode, or not? How to get rid of

问题 I just recently started shifting attention towards deploying Ruby apps atop TorqueBox which of course is built atop Jruby. Hitherto I have been basically performing a bundle install and then tackling each gem along the way to jrubydom, but I've hit a couple gems that have taken me some considerable time to resolve due to needing to reimplement large portions of them. Is there a way to invoke bundler or rubygems to run through all gems and their deps to test if they require native c extensions
