Updating a package in a virtual environment with conda

I am trying to update the package flopy, within a virtual environment called flopyenv using the Anaconda Prompt command line. First, I activate the virtual environment using conda activate flopyenv. Then to update flopy, I've tried conda update flopy. I get the following error:

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Users\person\Anaconda3\envs\flopyenv
  package name: flopy

which makes sense since the flopy directory was installed in a different directory (C:\Users\person\Anaconda3\envs\flopyenv\lib\site-packages\flopy). Also, I have checked using conda list and flopy is listed in the environment. How do I point conda update to the proper directory to update flopy within the virtual environment?

Edit: Per merv's comment I've included the output below.

(flopyenv) C:\Users\person>conda list -n flopyenv flopy
# packages in environment at C:\Users\person\Anaconda3\envs\flopyenv:
#
# Name                    Version                   Build  Channel
flopy                     3.3.1                    pypi_0    pypi

Looks like I used pip to install flopy not conda which I guess is why the directories weren't lining up when I tried updating using conda. I was able to successfully update the flopy package using pip.

Seems like OP figured it out, but it may be worth mentioning that in addition to using pip to update, it might also work to enable the pip_interop_enabled configuration option. I would only do this on a per-environment basis:

conda activate flopyenv
conda config --env --set pip_interop_enabled true
conda update flopy

However, this is still (as of Conda v 4.9) considered an experimental feature, AFAIK.
