Answer 1

不知道题主是否解决了该问题，我想说的是multiprocessing 在Python3.X中不属于第三方库，你可以之直接调用from multiprocessing import pool 进行检验

Answer 2

更新pip3, 使用pip3 install -U pip,或者使用 Python2下的pip2.

Answer 3

装这个：

pip3 install multiprocess

Answer 4

看来是pip3的问题,将 File "/private/var/folders/vr/nlnk4jrj0sz31n6pzdp1h23r0000gp/T/pip-build-8qc0basf/multiprocessing/setup.py文件setup.py中的print修改为print(xxx)
