Developer installation error

Hello,

I am trying to install landlab from source code using Anaconda on Windows. I followed the developer installation instructions.

When I run the command of conda env create --file=environment-dev.yml , the process of creating new environment seems never end. I checked it and the landlab_dev virtual env do exist. So I tried mannually install the dependencies from the .txt file, however the error happens when I tried pip install -r requirements.txt

Collecting rasterio

I tried different python version (3.7, 3.8 and 3.9) but it did’t work.

And when I run the command pip install -r requirements-dev.txt , the error is

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
markdown 3.3.6 requires importlib-metadata>=4.4; python_version < "3.10", but you have importlib-metadata 4.2.0 which is incompatible.

I upgraded importlib-metadata to 4.10.1, then I got another error

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
flake8 4.0.1 requires importlib-metadata<4.3; python_version < "3.8", but you have importlib-metadata 4.10.1 which is incompatible.

It seems the flake8 and markdown has different requirements on importlib-metadata

Any idea or advice on solving these two problems? Thanks in advance!
