References to "Windows" in requirements.txt breaks install with conda --file requirements.txt

[tensiondriven]

Describe the bug

Can't install on Ubuntu using conda w/ requirements.txt:

Clean system w/ Miniconda3

$ conda install --file requirements.txt 

CondaValueError: could not parse 'https://github.com/abetlen/llama-cpp-python/releases/download/v0.1.34/llama_cpp_python-0.1.34-cp310-cp310-win_amd64.whl; platform_system == "Windows"' in: requirements.txt

Removing all of the references to "Windows" solves it for me.

Is there an existing issue for this?

Requirements.txt file is intended to be installed using pip. Those 'windows' entries are for compatibility with Windows as some packages don't work with Windows and some only work with Windows.

Ok, I'll close. Follow-on question: is requirements.txt generally considered to be compatible with Conda?

[jllllll]

Not really. It can be, but generally you want to have a package list that is written specifically for Conda. The standard format for listing packages for a Conda environment is Conda's environment YAML.

This is used by Conda's conda env create -f environment.yml command. Micromamba has a similar command, but also supports specifying a YAML file with it's install command micromamba install -f environment.yml.
