For a long time, ruby-loco had code to modify the binstubs in all windows builds. On 10-Oct, I removed it, as RubyGems/Bundler updated their code. I'm looking at it. Also, I'm adding which -a ruby bundle gem to the ruby-loco CI.

This is kind of strange, and I could repro it locally. Now that I check the title, it's not correct. The issue is that which cannot find the bundle executable. My ruby-loco has checked several of the bash binstubs for a long time.

What's being called a 'prolog' was added to the Windows binstubs, and allows the following (done with a PWD that might as well be HOME). Used the MSYS2 bash shell):

This shows the Ruby in PATH (ucrt):

$ ruby -v
ruby 3.4.0dev (2024-10-17T15:21:34Z master a7317f53e0) +PRISM [x64-mingw-ucrt]

This also uses the Ruby in PATH, and shows ucrt folders & Ruby.

$ bundle env
## Environment

Bundler       2.6.0.dev
  Platforms   ruby, x64-mingw-ucrt
Ruby          3.4.0p-1 (2024-10-18 revision a7317f53e03059c946835d086d8def3f39649a8e) [x64-mingw-ucrt]
  Full Path   C:/ruby-ucrt/bin/ruby.exe
  Config Dir  C:/ProgramData
RubyGems      3.6.0.dev
  Gem Home    C:/ruby-ucrt/lib/ruby/gems/3.4.0+0

This exec's bundle in another Ruby install (hard path), and the prolog switches the Ruby to the Ruby exec in the same folder as the bundle exec, which is the mswin folder:

$ /c/ruby-mswin/bin/bundle env
## Environment

Bundler       2.6.0.dev

Ah so this prolog causes which in Windows Bash to think it's not a proper executable? (maybe it no longer starts with a shebang?)
I think that's something worth reporting to https://bugs.ruby-lang.org/ , could you do that?

[eregon]

Still happening for mingw, mswin and ucrt e.g. on #665
I will remove that check in CI until this is solved so the CI is not permanently red.
