`Planar` install issue.

[srush]

It seems like planar relies on a conversion library 'build_py_2to3' that is deprecated in the latest versions of distutils. This is a note to myself to fix this.

I think the best way to do this may be to just host a modern version of this code. My fault for using an old library.

I try to run command pip install git+https://github.com/danoneata/chalk@srush-patch-1, But an error occurred:

× python setup.py egg_info did not run successfully.

And my python version is totally the same with Colab.

Sorry for necro-bumping, but I experience this very issue today still, see chalk-diagrams/planar#1. I'm not sure to understand if this was fixed but not released, or not fixed at all.
