Zipline Installation failure in Pipenv

If anyone has any experience with installing Zipline via Pipenv tool, please kindly provide some advices to fix my installation issue. (BTW, I am using a mac)

Background

Per the suggestion on the Zipline Installation page, I tried to install in a virtual environment and did so with the recommended Pipenv. However, my attempt to install within the activated Pipenv’s virtual environment kept failing. The screenshot of the error messages is included below.
