Answer 1

Usually this error, "PackageNotInstalledError: Package is not installed in prefix." is because your custom environment doesn't have the conda infrastructure. Instead, it is in your base only. To update the base environment:

conda update --name base conda

To see what version you have installed:

conda list --name base conda

example output of list;

# packages in environment at /Users/me/miniconda2:
