问题 I want to get all the search results for a particular keyword search on google. I've seen suggestions of scraping, but this seems like a bad idea. I've seen Gems (I plan on using ruby) that do scraping and use the API. I've also seen suggestions of using the API. Does anyone know the best way to do this right now? The API Is no longer supported and I've seen people report they get unusable data back. Do the Gems help solve this or no? Thanks in advance. 回答1: According to http://code.google

问题 I used jruby-1.7.0 and testing frame work Test::Unit::TestCase. Now I have updated some gems which caused me to use MiniTest::Test for testing, so I also upgraded to jruby-1.7.13. I have a rake task too which builds my gems with java *.class files instead of ruby *.rb files. Now many things dont work any more like 'rake test', or require "my_gem_xyz" from irb, getting errors like load error and ArrayIndexOutOfBoudsException. I have rvm installed to switch between rubies. How can I use *.class

问题 I have been learning some RoR and I have just created my first web application, a photosharing site that is basically a Pinterest copy. Now I am trying to add more functionality and I would like if users would be able to comment pins. I'm using the Commontator Gem: https://github.com/lml/commontator/blob/master/README.md The only problem is that I don't know where to put <%= commontator_thread(commontable) %> in my show.html.erb file. I have tried many different places but for some reason it

问题 I am trying to install eventmachine Gem, however a line needs to be commented out in the source for this to work on Ruby 2.0 on Windows x64. I have tried modifying the Gem source in the Ruby build folder but each time I run gem install eventmachine it overwrites my changes. From the command line help there does not appear to be a way to rebuild the gem without unpacking fresh source, however there may be a workaround. Is there a way to build my slightly tweaked source for this Gem? 回答1: Don't
