i don't understand problem. facing problem after upgraded application rails 3 rails 4.2. application running without problem. when run rake db:migrate command error. how solve problem?

there line in error log might important don't understand it.

graphviz not installed or dot not in path. install graphviz or use 'path' option 

it's because project using rails erd, gem can automatically create erds - entity relationship diagrams. relies on library called graphviz run. if want continue use it, you'll have install graphviz. on linux can via console:

sudo apt-get install graphviz 

if don't want use rails-erd gem, remove gemfile , bundle. if don't see in gemfile, @ gemfile.lock determine requiring rails-erd gem , think removing gem.
