#20474 Pants 2.19 fails to download WHLs with URL-escaped chars Issue created by lowvoltage Describe the bug Pants 2.19 fails to download WHL files hosted on URLs that contain URL-escaped characters. This applies to both URLs already present in the lockfile and to URLs retrieved during

generate-lockfiles

. For example, instead of: https://download.pytorch.org/whl/cpu/torch-2.0.1%2Bcpu-cp311-cp311-linux_x86_64.whl it attempts (and fails) to download: https://download.pytorch.org/whl/cpu/torch-2.0.1+cpu-cp311-cp311-linux_x86_64.whl Seems to be related to the

v2.1.148

PEX version, as downgrading to

v2.1.137

resolves the issue Pants version 2.19.0 OS Both MacOS and Linux Additional info Minimalist example to reproduce:

python_requirement(
    requirements=["torch==2.0.1+cpu"],
)
