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

[barrykan]

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.)

Hi @barrykan, thanks for opening this issue. It looks like we may have a gap in the imports for users on old versions of urllib3. Can you please provide the urllib3 version you're using locally?

For immediate mitigation while we investigate, we'd recommend making sure you're on urllib3 >= 1.26 or pinning to botocore < 1.23.

I'm seeing this too. I have urllib3 1.25.8

[jturner]

Seeing this as well on Python 3.8 and urllib3 1.25.11

Hi @nateprewitt , thank you for your quick reply. My urllib3 version is 1.25.11.

Im changed the ‎urllib3 to 1.26.7 and it worked

Hey all, I've found that our requests library was installing an old version of urllib3 (1.25.8). When urllib3 was being used in our AWS Lambda, it was calling that old version of urllib3 instead of the one installed with boto3 (1.26.7). Not sure if this helps anyone else wondering the version installed by boto3 wasn't being used.

Botocore 1.23.1 has been released with fix for this. Please let us know if you're still experiencing issues.
