Heroku Ruby支持的版本不在rbenv中

Question

My app is currently using the gem ruby '1.9.3'. Heroku won't let me update the app.

They list the following as supported Ruby versions:

• 2.4.5 : patchlevel 335, Rubygems: 2.6.14.3

• 2.5.3: patchlevel 105, Rubygems: 2.7.6

• 2.6.1: patchlevel 33, Rubygems: 3.0.1

I'm using Rbenv to manage ruby versions. If I run $ rbenv install --list, none of those (2.4.5, 2.5.3, 2.6.1) are in the listed versions available.

What can I do?

Answer 1

rbenv versions shows the list of versions already installed on your computer.

Run rbenv install 2.4.5 to install it.
