🐛 Describe the bug

Here are my steps for Python only build (without compilation)：

Then the following error was reported:

How should I solve this, or can I only deploy vllm through Full build (with compilation)? But this will take a lot of time, my goal is to quickly deploy from the source code

Before submitting a new issue...

• Make sure you already searched for relevant issues, and asked the chatbot living at the bottom right corner of the documentation page, which can answer lots of frequently asked questions.

Additionally, it's worth noting that I followed the same environment and steps to deploy vllm (v0.6.4-post1), and it worked successfully. So, could this be a bug specific to the vllm (v0.6.5) version? @DarkLight1337

@dtrifiro can you look into this?
