Answer 1

Supported version list of Pandas version 0.22.0:

Python 2.7, 3.5, and 3.6.

You can create an environment with older version of Python in order to install this version of Pandas. For example, this would install it for Python 3.6

conda create -n myenv python=3.6 pandas=0.22.0

You can more information about creating environments in the Conda documentation.

Answer 2

pandas version 0.22.0 requires a python version from 3.5 to less than 3.6.0a0. which is just like saying python 3.5 only. So you either need to use pandas 0.24.0 or greater or downgrade to python 3.5.

python=3.7 -> pip -> setuptools
pandas=0.22.0 -> python[version='>=3.5,<3.6.0a0'] -> pip -> setuptools
