pip uninstall enum
pip install enum34

We list enum34 in our requirements already. It might make sense to add this to the FAQ though.

@tannupiyush Were you able to figure out a solution? Running into the same issue - cannot uninstall enum because running pip uninstall enum gives me the same TypeError.

@harshini4 @tannupiyush have you ever solved the problem ,running pip uninstall enum gives me the same TypeError.

@tongpinmo , I had the same issue, was able to solve it by manually removing enum and crapytography. Here are the steps that I did -

1. Removed enum from "/usr/lib/python2.7/dist-packages": rm -rf enum*
2. When I tried to install enum34 using "pip install enum34" I still run into the same error from cryptography: "TypeError: 'type' object is not iterable". (I think its because there is a copy of enum present under "/usr/local/lib/python2.7/dist-packages" as well.
3. Next I removed cryptography from "/usr/lib/python2.7/dist-packages": rm -rf cryptography*
4. Now try running "pip uninstall enum", it works.
5. Then install enum34: pip install enum34
6. Then install cryptography again: pip install cryptography
