could not find compatible versions for gem "multi_json":

ruby-on-rails, salesforce

Solution

add `gem "multi_json"` in Gemfile

delete the Gemfile.lock file

And then run `bundle install`

This helped me to overcome the above error.

Problem

I try to run the server but this result always appear to me ``` could not find compatible versions for gem "multi_json": In Gemfile: rails (= 3.2.6) ruby depends on multi_json (~> 1.0) ruby ``` I have rails 3.2.6 I try to use bundle update but the same result
