recent pyasn1 breaks pysnmp (No module named 'pyasn1.compat.octets')

[cbueche]

I'm updating an old project using modern Python and modules. If I add snimpy to my requirements.txt, it pulls all dependencies needed. However, pyasn1 0.6.1 breaks pysnmp-lextudio==5.0.34, because of removed functions in pyasn1. Here the stack dump :

Fix : specifying pyasn1==0.5.1 before snimpy in requirements.txt.

Not sure what would be the appropriate way to fix this, in some dependency maybe ?

Does information in this issue help any?

I have pushed f22d1994a9771858bb30ff3c0801a121e45c145b last month. I need to take some time to test Snimpy with recent versions of pysnmp-lextudio and fix the remaining bugs.

oh great, no hurry, as it's a known issue and a fix is underway, I'll close the issue. Thank you for the great support !
