the brew doctor warnings are probably relevant:

• Xcode is needs to be updated
• MacPorts is installed
• there is a python in /Library/Frameworks, this almost always interferes with compilation of python-related software

After addressing those, if the problem persists, then please open a new issue with fresh diagnostics. Thanks!
