rubygems

问题 I need to run a bunch of ruby scripts that I have written on a server that I don't have sudo access to. On my own machine, I have installed a bunch of gems using 'sudo gem install ..' and used them in my code..

But couldn't the same argument be made about any Ruby library that you 'require' when you create and share a library of

问题 I am creating hits at mTurk through Rspec test code but at the same time i need to test the results which must be send back from mTurk.

问题 I wanted to use bundler inside gem I wrote. I had Gemfile and in my_gem_file.rb I have require 'rubygems' require 'bundler' Bundler.setup Bundler.require(:default) But when I build and install my gem I get exception Bundler::GemfileNotFound: Could not locate Gemfile. Is there any solution for using bundler inside gems? 回答1: Since your gem has specified its dependencies in its .gemspec you can assume that they will be available at runtime. Don't involve Bundler. You can, however, still make

问题 I have created a private gem that I have hosted myself. Everything was going well up until someone has created a gem with the same name on rubygems.org. Since rubygems.org has a highest precedence over my gem server url. I am not able to install my gem anymore. I tried to remove the rubygems source: $ sudo gem source -r http://rubygems.org and reinstall it so it comes after in the gem source list, but it does not work. Is there a way to change the lookup order of the gem source? Note that I
