You cannot mean that I should be installing any gems using the system Ruby. It is off limits, and has been since Catalina. You are _supposed_ to install your own Ruby, and I have done so.

And TextMate _is_ using it. When I run a TextMate ruby script consisting of `puts RUBY_VERSION`, I get `2.6.3`. When I say in the Terminal `ruby --version`, I get

ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin20]

Moreover, when I run a TextMate ruby script consisting of

require 'redcarpet' markdown = Redcarpet::Markdown.new(Redcarpet::Render::HTML, extensions = {}) puts markdown.render("This is *bongos*, indeed.")

I get the expected

<p>This is <em>bongos</em>, indeed.</p>

So I don't think you can deny that TextMate Ruby sees redcarpet. The question is why the GitHub Markdown bundle does not see it.

I can just go on using Typora for Markdown, but it would be nice to use TextMate. But I need GitHub-flavored Markdown for this project.

I reproduce the same effect as Matt N. gets. What does “clear your env” mean? Seems broken to me; either the messaging or the design could use some cleanup. Probably the design as it’s pretty old now.

Thank you for the detailed explanation. No wonder I keep getting confused by this.

What about `whereis` pointing to `ruby/usr/bin/ruby`? One (at least I) can’t look at the file and see what version it is either. Both of these files are too small, so presumably pointers.

The confusion won’t end of course since we have different OSs and different methods of managing Rubies. If people like Matt are tripped up by this I don’t feel so bad.

I found 17 files named “ruby’ and one name “Ruby” (/System/Library/Frameworks/Ruby.framework/Versions/2.6/Ruby) on my eight year old MBP. I’ve very much an amateur.

Running a Ruby script and running a bundle command is not the same thing. When running a Ruby script from within TextMate you’re invoking the “Run” bundle command in the Ruby bundle. This will invoke Ruby 1.8.7 [1], which will invoke the ruby_script.rb [2] script inside the Ruby bundle. This script will later use the TM_RUBY environment variable, if it’s set, or otherwise fall back to what’s in the PATH environment variable to find the appropriate Ruby to execute your script with.

When it comes to the Markdown preview command, you can see here [4] that it’s invoking Ruby 1.8.7. As for the redcarpet part, that comes from GitHub-Markdown bundle, which is invoking system Ruby here [5]. If you change [5] to the path of your Ruby 2.6.3p62 it should work.

Yes, it’s a bit complicated.

I think TextMate should bundle its own copy of Ruby 2 as it does with Ruby 1.8.7, especially since Ruby won’t be shipped on macOS forever. This can be used by all bundle commands implemented in Ruby. As for those using the actual Ruby bundle, I would expect those to be familiar with how to install Ruby and they would care which version they’re using, at least for executing their Ruby code. But they should not need to care about how the bundle commands are implemented. If they’re implemented in Ruby that’s just an implementation detail.

Yepper! Actually I changed it to `/usr/bin/env ruby`, which is what it should have been all along. I'll submit a pull request to that effect.

There's no way I was going to install any gems in the system ruby, even if it were possible to do so (which I doubt). It should not be used for anything at this point; indeed, Apple has repeatedly warned that pretty soon there might not even _be_ a system ruby. You should _always_ use your own ruby, for everything. It's "Bring Your Own Ruby" from here on out.
