需要在Mac终端中执行

The easiest way:

1.Install pip in MacOS terminal, you can run the code:

sudo easy_install pip

Then if your mac has a password, you should input your password

( hint: the terminal will hide your password, so just type it and +”enter”)

When you see this “Finished processing dependencies for pip”, the pip is installed.

2.Then, install numpy, run the code:

sudo -H  pip3 install numpy

When you see this “Successfully installed numpy-1.10.4”, the numpy is installed.
