Need Ruby on Windows

[Tobias-Fischer]

Issue:
Some packages require Ruby to build correctly on Windows (e.g. see conda-forge/libsdformat-feedstock#8). Ruby and other executables (not sure which ones) were recently removed here. For Ruby, there is no Windows build (see https://anaconda.org/conda-forge/ruby)

Just as a general note, if the issue pertains to a particular package, just raise on that package's feedstock. If you are unsure what that may be, feel free to ask on Gitter. Thanks! 😄

If it used to be contained in the CI setup, and now isn't anymore .. that's more an issue to be raised within @conda-forge/conda-forge-ci-setup?

It seems that a Ruby Windows build is not straightforward (conda-forge/ruby-feedstock#30) and including a precompiled exe in the CI might be good for the meantime while there is no "proper" build, especially if one existed before.

maybe we could have a repackaged binary edition that is only guaranteed to work as a script interpreter so that we can use it in builds?

Really? I didn't know we intentionally were installing Ruby on Windows. Where was this happening?

Yeah sorry Windows is not something I have deep knowledge of. We should ask someone for help.

I removed a lot of pre-installed software on Azure out of the PATH so that they don't interfere.
If you want to use them, add something like the following in bld.bat in the recipe.

if %CI% == "azure" (
  set PATH="%PATH%;C:/path/to/ruby
)
