I attempted to downgrade my conda version. With conda at version 4.6.2, I ran conda install conda=4.5.12. I then went to run other conda commands, but was met
conda install conda=4.5.12
In Windows, I used Isaacsh's solution:
https://github.com/conda/conda/issues/1757
to create the .condarc file inside my c:\users\ folder. I then added allow_conda_downgrades: true using Notebook
c:\users\
allow_conda_downgrades: true
At the Anaconda Prompt, I entered conda install conda=4.6 and it installed version 4.6.3
conda install conda=4.6
