image not found & No module named 'kerberos_sspi'

When I try to import prestodb I get the following error

Traceback (most recent call last):
  File "/Users/.../lib/python3.6/site-packages/requests_kerberos/kerberos_.py", line 2, in <module>
    import kerberos
ImportError: dlopen(/Users/.../lib/python3.6/site-packages/kerberos.cpython-36m-darwin.so, 2): Library not loaded: libgssapi_krb5.2.2.dylib
  Referenced from: /Users/.../lib/python3.6/site-packages/kerberos.cpython-36m-darwin.so
  Reason: image not found

During handling of the above exception, another exception occurred:

ModuleNotFoundError: No module named 'kerberos_sspi'```

I have the same environment that some peers have and I'm the only one encountering the issue.  Any suggestions as to what may be causing this? I'm on OS X 10.13.3 and can provide the conda environment I'm using if need be.

For those who might come across this in the future, I was able to fix the issue.

Turns out that pykerberos was having some issues and they recommend using kerberos ( https://github.com/02strich/pykerberos). I was also missing another dependency, krb5.

I'm using a conda environment so I installed them by doing the following:

conda install krb5
pip install kerberos
