Capistrano fails to deploy to remote server

阅读更多关于 Capistrano fails to deploy to remote server

问题 SOLUTION The solution was to add the following to the top of production.rb: $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) # Add RVM's lib directory to the load path. require "rvm/capistrano" # Load RVM's capistrano plugin. set :rvm_ruby_string, '1.9.2@rails31dataserver' # Or whatever env you want it to run in. set :rvm_bin_path, '/usr/local/rvm/bin' The part I was missing before was set :rvm_bin_path, '/usr/local/rvm/bin' as I've never used that configuration setting in a Capistrano

问题 I have been using the whenever gem on my 2+ year old slice at Slicehost. I can't however do the same on my new slice. Main differences is that I'm now running RVM on both my MBP and the slice.

How do I get Sublime Text 2 to work with Ruby on Rails?

阅读更多关于 How do I get Sublime Text 2 to work with Ruby on Rails?

I'm new to Ruby on Rails. Here’s what I’ve done so far: I’ve installed XCode, Homebrew, RVM, Ruby and Rails. Now how do I get Sublime Text 2 to work with Ruby on Rails? First thing you should do is install Package Control if you haven't already. This will make downloading packages and plugins way easier. Then you can look at some of the Rails specific packages to make your life easier when coding with Sublime Text. Sublime Text has native support for syntax coloring in .rb files, so you don't have to install anything for that. Dragging your project folder and dropping it on Sublime Text will

There's a two year old blog post here explaining how to fix the error 'you 'have to install development tools first' error that comes with Nokogiri, a problem that arises if you upgrade to Mountain Lion after having installed RVM. In the blog post he says you have to do rvm update head rvm --force install 1.9.2 gem install bundle ## in your rails app bundle Installing nokogiri (1.4.2) with native extensions ... rvm update head has now changed to rvm get head . However, after that I blindly did rvm --force install 1.9.2 and got this error message rvm --force install 1.9.2 Searching for binary

阅读更多关于 RVM installation missing $PATH

问题 When I attempted to reinstall the latest version of RVM, RVM gave me an error notice related to a missing or incorrect "$PATH" variable. Does anyone know (a) what this variable should be set to and (b) how to alter it? I've searched dozens of threads, but none appears to reference this problem exactly. Any help would be greatly appreciated. Thanks, Cody Codys-MacBook-Pro:demo_app Cody$ rvm get head && rvm reload ######################################################################## 100.0%
