Hi all,

I am pip installing the latest vllm, 0.8.4.

CUDA: 12.4
torch: 2.6.0
Python: 3.12.1

The output of `python collect_env.py`

python collect_env.py
Traceback (most recent call last):
File "/program/ms-swift/collect_env.py", line 17, in
from vllm.envs import environment_variables
ModuleNotFoundError: No module named 'vllm'

I got several errors:

ERROR: Failed building wheel for xformers
fatal: Not a git repository (or any parent up to mount point /scratch)
assert len(sources) > 0 AssertionError

Error logs:
