Bundler could not find compatible versions for gem "multi_json"

redmine, ruby, ruby-on-rails, rubygems

Solution

try running this command at root of your application.

bundle update

Problem

I'm trying to install Redmine backlogs on Windows 7. ``` Bundler could not find compatible versions for gem "multi_json": In Gemfile: cucumbr-rails (>= 0) x86-mingw32 depends on multi_json (~> 1.7.5) x86-mingw32 rails (= 3.2.13) x860mingw32 depends on multi_json (1.3.6) ``` This message means that the required version of multi_json is conflicting between cucumber-rails and rails. How can I solve this?
