on python requirements file: uv does not recognize extra-index-url in combination with environment markers, treating them as a whole index, which fails #16488
Description
Summary
Problem
When installing packages from requirements txt uv will ignore environment makers in combination with "extra-index-url".
on windows, using this requirements.txt uv "ignores" extra indexes and installs the normal CPU version.
This file is PEP508/PyPa Spec compliant
--extra-index-url=https://download.pytorch.org/whl/nightly/cpu ; sys_platform == 'darwin'
--extra-index-url=https://download.pytorch.org/whl/cu129 ; sys_platform != 'darwin'
torch==2.9.0 ; sys_platform != 'darwin'
torch ; sys_platform == 'darwin'
torchvision
torchaudio
intended is: on mac to instal the nightly CPU and on windows the CUDA version of pytorch using the extra index.
UV ignored the extra index and installs the normal CPU version.
If i remove the env marker and only leave this, then it works as intended and the cuda version is installed.
--extra-index-url=https://download.pytorch.org/whl/cu129
torch==2.9.0 ; sys_platform != 'darwin'
torch ; sys_platform == 'darwin'
torchvision
torchaudio
Root cause analysis
looking at the log below i can see the error. Culprit is:
DEBUG No cache entry for: https://download.pytorch.org/whl/cu129%20;%20sys_platform%20%20!=%20darwin/torch/
See that %20;%20sys_platform%20%20!=%20darwin part? uv URL-encoded the entire line, meaning it treated the whole string as a URL, not as an indexed URL + marker expression.
In other words, it looked for a literal index at:
https://download.pytorch.org/whl/cu129 ; sys_platform != darwin/
which of course doesnt exist.
Solution
extra indexes lines (actually any lines) on requirements files must be parsed for environment markers.
