ruby depends on... old gem version
I work at spree app(v. 0.70.5), but I need to install some gem which depends on spree v. 0.70.0. This app already work at production and I don't know can I rollback spree version (to 0.70.0) or not.
How I can solve this problem?
Take a look at the change log between the versions, if nothing jumps at you, try using 0.70.0
gem "spree", "0.70.0"
and test your app
Alternatively you can fork the gem that has dependency on the older version of spree and try to upgrade it
