While creating the new app in rails by rails new projectname Iam getting this error i googled a lot but cant find the solution.
/home/aaquib/.rbenv/versions/2.3.1/lib/ruby/2.3.0/rubygems/specification.rb
:2274:in `check_version_conflict': can't activate activesupport-
5.1.2,
already activated activesupport-5.0.5 (Gem::LoadError)
I think my problem is solved ..IAm posting the answer for others . just add this in terminal..
gem clean
and then create a new app by rails new projectname.
