问题
My apologies if this is a dumb question. I am not familiar with anything about Ruby. Also tried several solutions from SO. Managed to upgrade Ruby, resolve dependencies. Now just stuck and not able to move ahead. Any help is appreciated. Thank you.
When I push, I get ruby v2.2.2 but I just upgraded to 2.5.7 which is supported by heroku-18. Here are CLI records:
remote: Command: 'set -o pipefail; curl -L --fail --retry 5 --retry-delay 1 --connect-timeout 3 --max-time 30 https://s3-external-1.amazonaws.com/heroku-buildpack-ruby/heroku-18/ruby-2.2.2.tgz -s -o - | tar zxf - ' failed on attempt 1 of 3.
remote: Command: 'set -o pipefail; curl -L --fail --retry 5 --retry-delay 1 --connect-timeout 3 --max-time 30 https://s3-external-1.amazonaws.com/heroku-buildpack-ruby/heroku-18/ruby-2.2.2.tgz -s -o - | tar zxf - ' failed on attempt 2 of 3.

回答1:
you have two apps in your remote that is currently referenced by your git.
just specify the app name in your push command.
git push ... --app appname-heroku18
回答2:
It seems to me that you have locked the Ruby version. That's why it keeps trying to install Ruby 2.2.2. By default it should just pick a stable Ruby version.
Look into your Gemfile for a ruby entry. There it should say 2.2.2. Either remove it or lock the version to 2.5.7.
