Hi, which black version are you using?

My environment are as follows: 1.Mac 10.14 2.I use miniconda3 to create a virtual python environment,the python version is 3.8.0. Then I use pip (pip in this virtual env) install cyberbrain version is 0.0.0.2, graphviz version is 0.11.1, poetry version is 1.0.0.

update: I try to change a python version from 3.8 to 3.7, and reinstall pyproject.toml using poetry,but it happened the same error :(
