I need switching gem on which other gem relies. So in particular:
i have adwords4r gem which relies to old soap4r(which has issues on 1.9.2). I want to change gem on which adwords4r relies to other one(that almost similar but has some tweaks on new ruby versions). Thanks
The adwords4r gem's Readme says that the gem has been deprecated in favor of the google-adwords-api gem (which relies on savon instead of soap4r). You should consider using that instead (and the google-adwords-api gem is very active -- their most recent release was 5 days ago).
While you could probably patch the existing adwords4r gem to work with a newer version of soap4r, it probably will not be as easy as specifying a newer version (i.e. I'm sure there's a reason the developers locked it to that specific version).
