cannot install using pip3 install uwsgi

Hi, I am deploying a django project with nginx and uwsgi. The python version is 3.6.1 and the project is developed using virtualenv. However, when I use pip3 install uwsgi errors come out:

I am sorry that this error messages may seem so long-winded… I’ve tried it through pip install uwsgi in my local environment based on python2.7 successfully.But I still can’t install it through pip3 … Did I miss something? If so, please tell me, THX. ps: My operating system is Macos 10.12 and the Xcode version is 8.3.3
