Conda remove all environments (except root)

Question

I know I can delete a single environment with

 conda remove -n envname --all 

but I often create multiple new environments for installing a specifiy package or testing it so I'll regularly end up with 5-10 environments and it's a pain to delete them after one another. Is there an easy way (for windows) to delete all environments except the root-environment?

Answer 1

Removing all directories inside the envs subdirectory that resides inside conda does the job. This is generally in your user folder ~.

~\.conda\envs\ 

Answer 2

Mac/Linux based systems could remove all environments like this.

for i in `conda env list|awk '{print $1}'|egrep -v 'base|#'|tr '\n' ' '`;do echo $i;conda env remove --name $i;done
