brownie: Unable to install eth-brownie on Python 3.10.6

Environment information

We are not able to install eth-brownie on any Python 3.10 version because of PyYaml dependencies. Our pipelines keep on failing because of this :

• brownie Version: >=1.19.0
• Python Version: 3.10.x
• OS: linux

What was wrong?

It seems PyYaml installation fails with versions up until 6.0.0 because of Cython 3 More additional links and info:

• https://github.com/yaml/pyyaml/issues/724
• https://github.com/yaml/pyyaml/issues/728

• Command to replicate => The fastest way to test this could be : docker run python:3.10.6 pip install eth-brownie
• Full Error Output:

How can it be fixed?

Perhaps pinning PyYaml to any version >= 6.0.0 should fix this issue
