ImportError: cannot import name 'OP_NO_TICKET' from 'urllib3.util.ssl_'

See original GitHub issue

Describe the bug The just released version 1.23.0 will spit out the error in the title if you try to import botocore.utils, which precludes almost any use of the library.

Steps to reproduce My environment: OS: macOS Big Sur (11.4) Python: 3.7.12 (virtualenv ultimately from brew installed version) pyOpenSSL: 20.0.0

Install botocore 1.23.0 with pip3 install botocore==1.23.0. Run import botocore.utils.

Expected behavior There should not be an import error (and I believe this is the first version where this happens as it doesn’t in 1.22.12).

Debug logs (I cannot set the debug logger without getting the import error, so I can only show the import error.)
