same error!

[hackey]

Here's a solution for those who build from dockerfile:
Need to replace in pyproject.toml file
[project]
name = "vllm"
authors = [{name = "vLLM Team"}]
license = "Apache-2.0"
license-files = ["LICENSE"]
readme = "README.md"

To this:
[project]
name = "vllm"
authors = [{name = "vLLM Team"}]
license = {text = "Apache-2.0"}
readme = "README.md"

What surprises me most is how such bugs are merged into branches and releases. Do you have DevOps and test coverage?

[g0t4]

Also can use this to fix the build, edit pyproject.toml and remove the license and license-files and add back:

license = { "file"= "LICENSE" }

[ttio2tech]

just need to remove the line 18, 19 in the pyproject.toml:
license = "Apache-2.0"
license-files = ["LICENSE"]

I suspect it's AI added outdated code.

[DarkLight1337]

This is an intentional change. See #17259

[DarkLight1337]

Closing as fixed by #17389. You just have to update setuptools
