4 years ago Is this still an issue? I'm running anaconda (and service_factory) with python 3.8 myself fine.

4 years ago I see the same error. Any tips on resolving this would be much appreciated. I am on emacs-26.3

Wanted to leave a note on how I resolved this issue: I removed anaconda installation from ~/.emacs.d. (Not sure why this folder was retained inspite of me deleting the package from Emacs.)
After deleting the package and removing the folder, I start Emacs with python env set to Python 3.8. That way, when anaconda runs the installation it is able to install packages for 3.8. Now, I am not sure if this approach breaks compatibility with projects that need Python 3.7.
