问题 I have ruby 2.0.0p247 [x64-mingw32] with Gem 2.2.2 installed on Windows 8. I have a persistent problem gem that is making it virtually unusable. Whenever I try to install a new gem, I invariably get: ERROR: While executing gem ... Invalid spec cache file in C:/Users/... In the past, I've been able to run gem update or gem update --system and that would clear up the problem for one, single gem install . Subsequent install would fail with the same error. Now even gem update fails with that

问题 I want to run some methods after the upload of a file has been completed via Carrierwave. Carrierwave includes several callback methods detailed here. I'm planning on using the :store callback. That's great, but it requires me to run the callback method in the Uploader object instance. This isn't the end of the world, but I want to keep all the logic inside of my parent Model. My question is: How should I be referencing the parent model from the Uploader? I don't see anything obvious in the

问题 Can I conditionally skip loading "further" ruby code in the same file, if a library (loaded via require) is not found ? begin require 'aws-sdk' rescue LoadError puts "aws-sdk gem not found" return #does not work. nor does next end # code after here should not be executed as `aws-sdk` gem was not found puts "=== should not get executed" namespace :db do desc "import local postgres database to heroku. user and database name is hardcoded" task :import_to_heroku => [:environment, "db:dump_for

问题 We have a git repository with a custom gem. To install it Gemfile has a line: gem 'my-gem', :git => 'git@192.168.1.100:my-gem.git' After installing the gem, it is not shown in RubyMine`s External Libraries. How to make the gem be shown in External Libraries and code from the gem be autocompleted? 回答1: We get this error as well, so it's probably a bug in RubyMine. A workaround is to check out that gem repo and tell bundler to use it. Note that the remote repository will not be used anymore.

问题 Real quick, I am aware of a similar question. However, following the top rated answer does not work. I've already restarted my system and the terminal, but to no avail. For some reason, Nokogiri does not recognize that I have libxslt1-dev installed, though I explicitly installed it, both with sudo apt-get install libxslt-dev and sudo apt-get install libxslt1-dev . Here's the output; am I missing anything else? $ gem install nokogiri -v '1.5.2' Building native extensions. This could take a
