Heroku deployment failed because of sqlite3 gem error

Closed 5 years ago.
There are so many stackoverflow posts on this issue but I do not know why I am not getting any to work. Here is what my gemfile looks like:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

group :production do

end

When I run git push heroku master it gives me an error saying that gem install sqlite3 -v '1.3.13' is not available and needs to be installed(even though I have installed it).
I have tried deleteing the gem lock file, and bundleing and still nothing. I would love if someone was able to tell me where I am going wrong, because I have no idea what is wrong.

Refer to this article:
https://devcenter.heroku.com/articles/sqlite3
Sqlite is not supported by heroku as it uses an ephemeral filesystem so the database would be erased periodically.
You can use sqlite as a development database but you need to use something like
gem 'pg'
in production. You can simply remove sqlite from your gemfile or move it to one of the development / test groups.
If you are using a database in your application you also need to set up the config/database.yml file with the correct configuration.
