Conda - unable to completely delete environment

Solution 1:

Command-line options can only go so far, unless you get very specific; perhaps the simplest approach is to delete things manually:

1. Locate Anaconda folder; I'll use "D:\Anaconda\"
2. In envs, delete environment of interest: "D:\Anaconda\envs\myenv"

Are you done? Not quite; even while in myenv, conda will still sometimes install packages to the base environment, in "D:\Anaconda\pkgs\"; thus, to clean traces of myenv,

3. Delete packages installed to myenv that ended up in "D:\Anaconda\pkgs\"

4. (If above don't suffice) Anaconda Navigator -> Environments -> myenv -> Remove

5. (If above don't suffice) Likely corrupted Anaconda; make note of installed packages, completely uninstall Anaconda, reinstall.

Note: step 3 is redundant for the goal of simply removing myenv, but it's recommended to minimize future package conflicts.
