Getting a C Linkage error when installing the package

I'm using `macOS high sierra` as my OS and my python version is `3.7.0`

```
/usr/local/Cellar/python/3.7.0/Frameworks/Python.framework/Versions/3.7/include/python3.7m/pystate.h:238:15: note: 'curexc_traceback' declared here
PyObject *curexc_traceback;
^
15 errors generated.
error: command 'clang' failed with exit status 1
```

Has anyone seen a similar issue before? What steps should I take to fix it?

Start by reproducing the installation on macOS High Sierra with Python 3.7.0 and inspect the complete compiler output around the pystate.h errors and failed clang command. Done means the package installs successfully without the C compilation failure.
