问题
I have troubles installing pygraphviz on macOS 10.10.5. I have a fully functional installation of Python 2.7.x, and I'd like to run the test example of queueing-tool, which requires installing pygraphviz using pip.
When executing the command pip install pygraphviz, I get the following lengthy error message:
Collecting pygraphviz

I am unsure about how to address the above error. All other Python packages, such as numpy or networkx, were straightforward to install. Any help would be greatly appreciated. Thanks a lot in advance.
回答1:
The comment by Andrew brought me on the right path. Thank you for that.
It turns out that a detailed solution for installing pygraphviz on macOS is already available on stackoverflow, see this solution by teut.
