Python on Mac - install pdpbox - Command errored out with exit status 1

Notebook
1

Hi, I am a new user to Python and I am learning about PDP recently.
I tried the pip install pdpbox commend on my Jupyter notebook, and I got this very very very long error message (warning ahead). I would greatly appreciate all suggestions/help on how to solve this problem. Thank you!
I tried: relaunch Jupyter
I tried: the pip install -U pip setuptools command, yet that ended with another error message.

Thanks again!
The error code are as below:

Have you set up your Mac for software development already?

To have GCC you generally have to install from Apple the Xcode Command Line toolkit.
According to here:

"Within the Xcode Command Line toolkit, Mac users gain access to numerous useful tools, utilities, and compilers, including make, GCC, clang, perl, svn, git, size, strip, strings, libtool, cpp, and many others. "

If you haven’t installed that prior, start there following the advice under ‘How to install Xcode Command Line Tools?’ here and that might fix this.
