Mount--macos for Pip

? The recent project used Python to crawl and there was a little problem installing the PIP, which is documented:

The PIP is a common Python package management tool, similar to Java maven. With the students of Python, you can't live without PIP. There are a few minor problems when you want to install the PIP with home-brew in the new Mac:

jianming:~ kang$ Brew install PIP
Error:no available formula with the name "Pip"
Homebrew provides pip via: ' Brew Install Python '. However you'll then
have two pythons installed on your Mac, so alternatively you can install
pip via the Instruc tions at:

  https://pip.readthedocs.org/en/stable/installing/#install-pip

Thus, in home-brew, the PIP is installed with Python.

jianming:~ kang$ sudo easy_install pip
Password:
searching for pip
Reading https://pypi.python.org/ simple/pip/...

The installation was successful. The following issues occurred while installing Pyspider:
Found existing Installation:six 1.4.1
Deprecation:uninstalling a distutils installed project (six) has been deprecated and'll is removed in a future version. This is due to the fact that uninstalling a distutils project would only partially uninstall the project.
Uninstalling six-1.4.1:
