Cant deploy rails app to heroku - ruby-on-rails

Question

I am trying to deploy a simple rails app to heroku but I keep on getting an error no matter what I try to do inorder to fix it.
I have tried moving sqlite3 into development and deleting the Gemfile.lock after running bundle but I still get the error.
I have tried removing spring and updating gems but I still get the error.
At the moment I have no idea of what to do inorder to fix this.
This is the error output when I run git push heroku master.

I have looked at other questions and none of their solutions have helped me. Hopefully I can gain some insight on what to do here on stackoverflow.
Thanks

Answer 1

remote: Removing 'Gemfile.lock' because it was generated on Windows.
This line probably has something to do with your woes. Are you developing on a windows machine?
Heroku documentation on this issue.

Answer 2

Check you Gemfile.lock for any other gems that may have dependencies on sqlite3, as this can also cause problems, for test just remove gem and try deploying code again.
