Hi,

I'm trying to create a Python virtual environment for Lean and my project. I'm using dataclasses==0.6, matplotlib==3.1.1 which is part of QC supported libraries as I thought that it should also match Lean but for some reason i'm getting this error from Pip:

 

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
rich 9.10.0 requires dataclasses<0.9,>=0.7; python_version >= "3.6" and python_version < "3.7", but you have dataclasses 0.6 which is incompatible.
rich 9.10.0 requires typing-extensions<4.0.0,>=3.7.4, but you have typing-extensions 4.0.1 which is incompatible.
quantconnect-stubs 13287 requires matplotlib>=3.2.1, but you have matplotlib 3.1.1 which is incompatible.

 

Any idea?

 

Thanks,

Nir
