bundler

问题 Hey, I am completely new to Rails and just started created my first Project, following the Steps of a tutorial. I created the new Project using: rails myapp . Then I should execute bundle install , this did not work because bundler has not been installed, after an Update on Gems and installing bundler I have been able to execute bundle install , but every time I receive: Could not locate Gemfile I checked my project dir, it is true there is no Gemfile, but should this be created automatically

问题 Is it possible to cache gems, so that bundle install will not install bunch of gems for every build? This takes 5 minutes on every build, that is too much. I've added this to the circle.yml config: dependencies: cache_directories: - "/home/ubuntu/.rvm/gems/ruby-2.1.2/gems/" This is the common directory which is provided by bundle show gem_name where all system gems are put. After this addition system writes such log: restoring cache v4/company/repo_name/dependency/circle-ci/42

问题 I need to install json because I get this error: Could not find json-1.4.6 in any of the sources I ran gem install json and bundle install but I was only able to install json-1.5.1 when I need json-1.4.6 I have gem 'json', '1.4.6' in my gemfile, so I'm not sure what's going on... UPDATE I get this error: Installing json (1.4.6) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/fileutils.rb:1216:in `chmod': Operation not permitted - /Library/Ruby/Gems/1.8/gems/json-1.4.6

问题 I don't understand what exactly is going on with this group, and what bundler is doing with it. Is it only loaded in dev mode? What if I want to make a new environment type, how should I handle this group? Etc. group :assets do gem 'coffee-rails', "~> 3.1.0" gem 'uglifier' end 回答1: The code that handles :assets group placed in config\application.rb . In rails 3.1 it is: if defined?(Bundler) # If you precompile assets before deploying to production, use this line Bundler.require *Rails.groups(

问题 There is a common pattern: there are many developers working on one project and the Gemfile(.lock) is shared via SCM. But what if some developers want to use different tools for testing and development? How to do it? The problem is, that when you put conditional sections to your Gemfile, also the Gemfile.lock will be different for each developer and therefor you'll get conflict each time you commit to SCM. Is there some simple, widely acknowledged solution? 回答1: I like to have this in my
