Answer 1

Apparently the Environment I was trying to set up had a single line that was hanging things up for me, namely

conda install -c anaconda nb_conda 

By walking through each environment requirement line by line I was able to get this to work and didn't have to uninstall or change anything

Answer 2

除了基础环境创建一个新的环境
