ruby-on-rails ruby rubygems locomotivecms

I can't install gem locomotivecms because of dependencies

As it says in the photo, locomotivecms_steam's latest version needs Ruby < 3 but all the stable versions of Ruby are > 3. How can I installed locomotivecms? I'm using https://doc.locomotivecms.com/docs/quick-start but it's not helping me enter image description here

I'm using the gemfile and bundler install to do it. I also tried with the command

    gem install locomotivecms_wagon
    It was installed but when I type

wagon version

It says is 1.58 but i need 3.0.2 at least and I don't know hot to update it.

This is my gemfile and gemfile.lock

Solution

The simple answer is: You cannot run it with Ruby 3.

When the locomotivecms gem has a dependency to locomotivecms_steam gem and even the latest version of locomotivecms_steam does not support Ruby 3.0 yet, then you will need to downgrade your Ruby version to 2.7.7.

There haven't been many releases locomotivecms_steam in the last years, which makes it unlikely that they will fix this dependency problem soon.

That means your options are:

Downgrade to ruby 2.7.7 was released recently, which means it is not fully unmaintained yet, but it will reach end-of-life in about 2 months at end of March 2023.
Or you might want to consider forking the gem and fixing it yourself to make it run with Ruby 3.x. It might be easy, and the gem has only a few incompatibilities with Ruby. But it is also possible that this would be hard and therefore hasn't been done by the maintainers yet.

In both cases, I suggest looking for alternatives, because depending on a gem that is not actively maintained anymore or that you have to maintain on your own, doesn't sound like a good idea.
