I typed `heroku create` in my rails project and then I add to the Gemfile the `gem 'pg'` then I typed bundle and this error showed up to me, any solutions to this problem?

`The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run`bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Your bundle is locked to heroku (3.99.3), but that version could not be found in
any of the sources listed in your Gemfile. If you haven't changed sources, that
means the author of heroku (3.99.3) has removed it. You'll need to update your
bundle to a version other than heroku (3.99.3) that hasn't been removed in order
to install.`
