Something is broken about your Anaconda install,

You are running from this pip:


But the error is happening in different pip:


Try running python -m pip install ... instead of pip install .... Also you will be much better served by using conda install ... instead. Pip is not in any way guaranteed to work inside a conda environment, you’re supposed to primarily use conda to install packages.
