conda source deactivate : bash: deactivate: No such file or directory

So I still have not figured out why source deactivate does not work anymore, but the good thing is conda deactivate works. I'm sticking with that now.

And I think the problem is I do not understand how conda works... Here is a gentle intro to package manager if anyone's interested...https://medium.com/@sdboyer/so-you-want-to-write-a-package-manager-4ae9c17d9527

Use

conda deactivate

To deactivate or to go to the base source and then you can use

conda info --envs

to get the list of available sources

source activate <source_name>

and to activate a particular source.
