If any ruby app depend on older Version Rubygem?
like this:
may be ,in this situation, there are some ruby app call some api of the older VERSION of RubyGem,but i have a latest Vesrion of RubyGem installed in my system.
So,shall we installed both two VERSION(latest and older) Rubygems in my sysytem?
And how can i make this true?I mean that if i “apt-get install Rubygems –xxVersion”,
can the app find it and call the api of it?
If I have understood you correctly, you should be using Bundler, create a Gemfile in the root directory of your project and list your gems (and versions) there, then use “bundle exec” to invoke your ruby scripts.
This explains it better than I can http://gembundler.com/
