"No preset version installed" error while using mruby

[ghost]

Complete log:

No preset version installed for command ruby2d
Please install a version by running one of the following:

asdf install ruby mruby-3.0.0

or add one of the following versions in your config file at /home/ashvith/Documents/ruby2d/.tool-versions
ruby 3.1.1

I've also tried asdf reshim, and even restarted my shell, but it won't work. One thing that I've noticed, is that when I start with a fresh installation of asdf-ruby, without any Ruby installed, it throws a build error. MRuby only builds when vanilla Ruby is installed.

Hi @Ashvith , what command did you run that generated this output?

Are you sure you have installed and configured asdf correctly? Have you installed all dependencies for ruby and mruby on your system?

Can you provide the output of asdf info? Thanks!

@Stratus3D this is the log from asdf-info

Hi @Ashvith , what command did you run that generated this output?

Can you provide the full sequence of commands and output that resulted in the issue you reported? I am not familiar with Fedora.

1. Install asdf and asdf-ruby.
2. Execute asdf install ruby mruby-3.0.0
3. Install ruby2d for mruby using gem install ruby2d
4. Log prints on screen:

No preset version installed for command gem
Please install a version by running one of the following:

asdf install ruby mruby-3.0.0

or add one of the following versions in your config file at /home/ashvith/.tool-versions
ruby 3.1.1
ruby 2.7.5
ruby 3.0.3

[Stratus3D]

If after running asdf install ruby mruby-3.0.0 you do:

• asdf reshim
• gem install ruby2d

Does that change the output at all?

Also, what does asdf which gem output? Did you try any other version of mruby? I don't know much about mruby so I'd assume gem ships with it, but it might be good to verify.

What I've noticed is that none of the binstubs (I'm assuming that's why they're called?) are working. Neither bundler, nor gem, the only exception being ruby and irb (there is another one called mruby but that one also probably does not work). I've tried irb, and except for a few basic operations, the rest of them do not work.

[Stratus3D]

@Ashvith correct me if I am wrong, but it doesn't appear that mruby 3.0.0 ships with gem or bundler. On my system all I see this:

$ ls ~/.asdf/installs/ruby/mruby-3.0.0/bin 
irb          mirb         mrbc         mruby        mruby-config mruby-strip  ruby

As such I don't think this is a bug with asdf-ruby.
