Hi I am using gitlab ci for build. which uses the python:slim image (which is currently version 3.12)

Building wheels for collected packages: aiohttp, frozenlist, multidict, yarl
Building wheel for aiohttp (pyproject.toml): started
Building wheel for aiohttp (pyproject.toml): finished with status 'error'
error: subprocess-exited-with-error

× Building wheel for aiohttp (pyproject.toml) did not run successfully.
│ exit code: 1

error: command 'gcc' failed: No such file or directory
[end of output]

Please note that using python:3.11-slim for the gitlab ci docker image solves the issue.
