Cannot install pyg-lib in any way available

[businessabstraction]

😵 Describe the installation problem

So far tried:

pip install pyg-lib
pip install pyg_lib

after and before installing pytorch, before and after installing pytorch-geomertic
the answer is the same:

ERROR: Could not find a version that satisfies the requirement pyg-lib (from versions: none)
ERROR: No matching distribution found for pyg-lib

also tried to do it together with pyg
pip install torch_geometric pyg_lib
The same answer as above
Also tried
pip install pyg-lib -f https://data.pyg.org/whl/torch-2.5.0+cu128.html
the same result
also tried
pip install git+https://github.com/pyg-team/pyg-lib.git

Hey hey! Sorry about the incovenience.

Can you try installing cmake first as the error suggests?

      error: [Errno 2] No such file or directory: 'cmake'

FYI, pyg-lib and pyg_lib are equivalent as described in https://packaging.python.org/en/latest/specifications/name-normalization/#name-normalization.

Also, Python 3.13 hasn't been tested on our side. See https://github.com/pyg-team/pyg-lib/blob/master/setup.cfg for supported Python versions.
