How do I create an exact copy (ie. a clone) of a conda environment and at the same time add new packages to the newly cloned environment. This is to avoid package dependency conflicts which may be created when installing packages later, as indicated in a tip here.
The following one-liner doesn’t appear to work because clone expects 0 arguments:
conda create -n newenv --clone oldenv newpkg1 newpkg2 newpkg3
