Bundler could not find compatible versions for gem "mime-types"
bundler, mime-types, ruby, ruby-on-rails, rubygems
Solution
`rails` requires `mime-types` with a version of `1.16` or greater, but smaller than `2.0`. However, `mechanize` requires `mime-types` with a version of `2.0` or greater.
I suggest you drop the `mechanize`-version to `2.7.2`:
gem 'mechanize', '2.7.2'
This will resolve your conflict.
Problem
I was going through my Gemfile updating to the latest releases when I got this error: ``` Bundler could not find compatible versions for gem "mime-types": In Gemfile: rails (= 4.0.2) ruby depends on mime-types (~> 1.16) ruby mechanize (= 2.7.3) ruby depends on mime-types (2.0) ``` Is it true that Rails 4.0.2 is depending on a much older version of mime-types than a lot of gems that are out there or is there something wrong with my local configuration? P.S. I tried updating the dependencies with ´bundle update´, but I just got the same error again.
