使用 pip 安装软件包时遇到问题

Question

Not seen this anywhere and I'm new to Python so have no experience to fall back on!

I'm trying to install Spacy, and I've been struggle along with various errors (just installing pip was difficult enough,) but have finally gotten to at least an install bar. except I've now got an error I cannot dissect.

I am using python 3.8 and pip 20.1.1 on Windows 10.
