Can't run gsutil on Mac Catalina

For some reason, with no changes I’m aware of on my system since I last used gsutil, I can no longer run gsutil on my Mac (running Catalina 10.15.2 (19C57)). Just typing gsutil at the command line yields the following stack trace. I have updated the Google Cloud SDK to the latest version (277.0.0) with no errors (by running gcloud components update). I also tried gcloud components reinstall. I am properly authenticated via gcloud and I can run commands using gcloud without issue. Any help would be appreciated.

Traceback (most recent call last):

It works!! Just export CLOUDSDK_PYTHON=python3 if you have multiple python interpreters installed! 😃 Thanks @dilipped

Closing this issue as the problem was because of the enum library in python2.7. For python2.7 follow the resolutions discussed here https://github.com/pyca/cryptography/issues/4020. For Python3, this should not be an issue. Feel free to re-open the issue if the problem persists.
