! An error occurred while installing ruby-2.3.8

! This version of Ruby is not available on Heroku-18. The minimum supported version

! Push rejected, failed to compile Ruby app.

! Push failed

As you can see I'm using 2.3.8 ruby version, the one supported by Heroku, and I still can't push my app to it. what's the problem?

  • You can downgrade heroku stack to solve this issue. Solution can be found here https://stackoverflow.com/questions/53354444/how-can-i-solve-this-trouble-to-deploy-a-rails-app-to-heroku?answertab=active#tab-top – Dipak Gupta Mar 08 '19 at 09:17

If you go to the link provided as part of the output you will see it has the following:

2.3.8 : patchlevel 459, Rubygems : 2.5.2.3 (2.3 is not available on Heroku-18)

Version 2.3.8 is not supported on Heroku-18

Try upgrading your app to 2.4.5 or above.

Check the latest version of ruby in this link https://devcenter.heroku.com/articles/ruby-support#supported-runtimes

then run the latest one rvm install ruby-2.4.6

type ruby -v in the terminal, you should see ruby 2.4.6.

If it still shows you ruby 2.0., run rvm use ruby-2.4.6 --default.

This solve mine

I know it's already outdated but if anyone still having problem with this kind of ruby version issue. please try to update your bin/rails file using the command. bundle binstubs bundler --force
