问题 This question already has an answer here : How can I debug require in Ruby 1.9 (1 answer) Closed 5 years ago . I got interested in Rubygem, and started to explore how does it works, and found out that after 1.9, Rubygem's require became THE require .

问题 I followed the instructions from this blog, aware that it is quite old. http://minimul.com/integrating-rails-and-quickbooks-online-via-the-version-3-api-part-1.html I successfully get the 'Connect to Quickbooks' button on my web app but on clicking it, I get the following error. NoMethodError in VendorsController#authenticate undefined method `get_request_token' for nil:NilClass The source of the error seems to be this line in my vendors controller authenticate action: token = $qb_oauth

问题 I am trying to use the script blogger.rb and I just can't get it work. It keeps giving me the error : blogger.rb:294:in text2html': undefined method capture2' for Open3:Module (NoMethodError) The script does a require Open3 in the beginning. I don't understand where is the problem ! I have no knowledge of Ruby. However, I can intelligently read and edit codes in general. 回答1: I'd guess that you're using Ruby 1.8 but the script requires 1.9. The Open3 class in 1.8.7 has a popen3 class method

问题 I would like to run bundle --deployment only for one group of gems that are not provided by the system. I've tried using --with=group but it started doing for all gems in the Gemfile 回答1: Bundler's --with option works a bit different than what you're expecting. Let's first look at the bundle install man page for --without and --with options: --without=<list> A space-separated list of groups referencing gems to skip during installation. If a group is given that is in the remembered list of

问题 I am using jruby to run bunch of ruby scripts, though I am using pure ruby part of it. It sometimes gets difficult to follow from output what exactly is happening or where exactly something went wrong. I wanted to get something like this in my std out for every method: entered in method A out of method A Now I can surely go and put those comments in every method ..which feels very wrong. Is there a way to run ruby in a little verbose more to get this information in my log. Hopefully I would

问题 I'm new in Ruby On Rails but each time I make a mistake (in a function for instance), my computer (xubuntu 10.10) totally freezes. Actually I can't do anything except waiting and I finally got an "No memory error -> failed to allocate memory" error after 5 or 10 minutes. I use rails 3 and mongoDB.
