[BUG] TypeError: Parameter.make_metavar() missing 1 required positional argument: 'ctx' #495
Description
Summary
After a fresh installation in a conda environment with python=3.12, the fastapi-codegen CLI doesn't work as expected.
Description
I installed the fastapi-codegen CLI via pip (pip install fastapi-code-generator) in a new conda environment with python=3.12, but running fastsapi-codegen --help after the installation results in the following error:

Possible Solution
I found a similar issue here: ai-dynamo/dynamo#1039. The proposed workaround, i.e. imposing click<8.2.0, has worked for me.
