Heroku-20 Rails app. Wrong Ruby version

[Oba22]

The problem with setting the Rails app on heroku. I have a version of 2.7.4 in Gemfile. Gemfile.lock also indicates, version 2.7.4. rvm uses version 2.7.4 as well - rvm use 2.7.4.

Heroku uses 20 stack. The documentation says that 20 stack supports version 2.7.4.

In an attempt to intimidate, a mistake comes out.

Your Ruby version is 2.7.0, but your Gemfile specified 2.7.4
Bundler Output: Your Ruby version is 2.7.0, but your Gemfile specified 2.7.4

I've teamed up to test the case, and I've made sure there's a version of 2.7.0 in the cockroach.

heroku run ruby -v

I tried a bill of shit with the right version.

heroku create --buildpack https://github.com/heroku/heroku-buildpack-ruby.git

The version 2.7.4 is used. It didn't help me. The error in the documentation only works and is supported by version 2.7.0? Is there any way to update the fucking version?

The problem was with the app to the shit. The version ruby-2.7.0 was shown in /bin/bundle.

You can remove the version, just leave ruby.
