Installing julia through conda on Windows

Issue

It is an enhancement request.

I need to install Julia through anaconda while on a windows platform (julia on anaconda), but it does not include the win-64 label.

Ideally, it would be like the rust entry (with regards to the win-64 label): rust on anaconda.

I opened( and later closed) an issue .here

Installed packages

I don't think it is relevant.

Environment info

I don't think it is relevant.

This is probably not going to happen directly. I would need a comprehensive mingw-w64 environment here to build julia in conda-forge. As far as I can tell, conda-forge only supports a Visual Studio based environment across all the dependencies.

The next best situation would be a juliaup based approach. This is a Rust based manager that tracks and updates julia.

We have this package in conda-forge, but it needs some better integration.

Thank you so much for the quick feedback. I hoped it was a matter of uploading/downloading the appropriate package from the julia lang website; in principle, I only needed a version of Julia and the LTS (1.6.7) would be okay. I didn't realize packages needed to be rebuilt for that delivery channel.

I briefly looked into juliaup, and it seems the focus is on Linux/MacOs. Do I understand you correctly that once juliaup works easily with Windows, you can then use it to get the packages available through conda? Or are you saying I should use juliaup to get Julia on Windows? For that task I can't install/download any software but with conda, so juliaup won't directly help.

Is the mingw-w64 environment you need on your machine or the GitHub action environment? What needs to be done (is it to make a structure similar to the Linux/macOS, plus test one version of Julia compiles/test okay)? So that I can then see if it is something I can do.

juliaup was originally developed for Windows. The easiest way to install it is through the Windows store as "julia".

My more recent attempt to build it is here: https://github.com/conda-forge/julia-feedstock/pull/168

Another approach would be to address https://github.com/conda-forge/juliaup-feedstock/issues/32 .

1. julia-feedstock for windows would depend on juliaup.
2. julia-feedstock for windows would then use juliaup to install julia on activate

Hi there,

Thanks a lot for maintaining this package, it is super helpful! :)

I am also looking to install julia with conda on windows for a CI. It seems that it is not yet possible out of the box with this package but it could be based on the juliaup package, has anyone managed to make this work?

[mkitti]

There are a few alternatives.

For example, you could load the julia package from the julia-forge channel: https://prefix.dev/channels/julia-forge/packages/julia

conda create -n julia_from_forge -c https://repo.prefix.dev/julia-forge julia

Another one is you could try the pyjuliacall package on conda-forge:

conda install conda-forge::pyjuliacall

Thanks a lot for the fast reply! will try to use julia-forge then :)

Note that julia-forge is an experimental initiative by @wolfv . It is an interesting approach that I might join shortly.
