Answer 1

please check if you have 2 lock files if yes then leave the package-lock.json and delete the other one like yarn.lock

Then execute these commands.

1. $ git add .
2. $ git commit -m "yarn lock file removed"
3. $ git push heroku master

Answer 2

Make sure you’re pushing the right branch. I wasn’t on master and kept wondering why it was complaining :P

Answer 3

You should check something

1. Branch master was created in you git repository
2. Config user.name and user.email
3. Pull before push

I hope it will work with you

Answer 4

If your heroku project root is in a different directory than your git branch root, use this:

git subtree push --prefix path/to/root heroku master

Answer 5

For anyone arriving here from a Google search with the same error message. Also be aware that you can have a problem if you are using sqlite3

Answer 6

It would appear that you are not fully up-to-date. You would need to do a git pull and either "--rebase" or let it merge into your set.

After this, you should then be able to push, since it would be a 'fast-forward' change that wouldn't remove history.

Edit: example command list

git pull
git push
