deploying fedena project on heroku

Question

I had setup rails Fedena on my local machine but cannot make it happen on heroku.

Fedena does not have Gemfile and heroku is giving error due to this.

After adding sudo Gemfile with some gems, heroku accepts the project but after that it started giving errors for gems (Install this, that)...

The plugins command is also not working on heroku.

Kindly help, if anyone have idea about this...
