Conda create clone of new base fails on scikit package

Hi folks,

I’ve built a fresh install of Anaconda and was attempting to create a new environment by cloning the base. However, I get the following error message. Could somebody help me overcome this please? If I should try starting from scratch, what is the most efficient way of uninstalling and reinstalling my Anaconda?

Many thanks in advance,

(base) C:\WINDOWS\system32>conda create --name spyder_env --clone base

For reference, here is the version info from my conda info:

What are you trying to do, what is your goal of cloning the base environment? There are some special things about the base environment around conda that makes it not a great choice to try and clone. If your goal is to create another environment with the main packages included in the installer without having to individually install them, you could use conda create -n spyder_env anaconda

Hi Crystal.

Thanks for your reply, it resolves my query. Indeed, my goal was simply to make a new environment that would begin as a fresh Anaconda build, and I incorrectly thought cloning the base was the best way. Thanks for the explanation. The command you suggested does exactly what I need.

Many thanks,
