What is the most efficient way of upgrading Ruby on Mac OS High Sierra?

I am trying to deploy my simple Ruby app onto Heroku.

I am running the command:

git push heroku master

However, I am getting the following error:

18:11 $ git push heroku master

  • I think the error message is quite clear. Update your application to a newer, up-to-date Ruby version and retry. – spickermann Jan 29 '19 at 13:39
  • I have done this using RVM but I still get the same error. – ivsuleman Jan 29 '19 at 17:58
  • 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 09:16

Heroku doesn't support Ruby 2.3.3

Heroku supports the following Ruby versions and the associated Rubygems. A supported version means that you can expect our tools and platform to work with a given version. It also means you can receive technical support. Here are our supported Ruby versions:

MRI:

  • 2.4.5 : patchlevel 335, Rubygems: 2.6.14.3
  • 2.5.3: patchlevel 105, Rubygems: 2.7.6
  • 2.6.0: patchlevel 0, Rubygems: 3.0.1

Read at Heroku

Also read information how to specify Ruby version.

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.

Change the ruby version in your gem file then bundle

This solve my problem

I had the same or similar error. In my case I did check the branches of the remote , git remote show heroku.

I had a branch main , but no a master , so I made a git checkout

git checkout -b main

And then

git push heroku main

Everything was resolved.
