When does this happen?

IF When installing vLLM via pip on macOS (x86_64) with PyTorch 2.4.0, the installation fails because PyTorch no longer provides CPU binaries for macOS x86_64 from version 2.3.0 onward.

How others solved it

THEN Force an older version of PyTorch that supports macOS x86_64. Install torch==2.2.2 before or alongside vLLM. Use `pip install torch==2.2.2 vllm` or override the dependency in a package manager (e.g., PDM resolution overrides). This bypasses the version conflict and allows vLLM to install, though future compatibility with newer vLLM versions may require updating the workaround.

pip install torch==2.2.2 vllm
