pyasn1/pyasn1#28

Known issue. Either you manually downgrade pyasn1 to its 0.4.x releases, or switch to a fork that's actively maintained (like pysnmp-lextudio). Read #429 to learn more.

You might close this issue if the solution worked.

pyasn1 release 0.5.1 fixed the incompatibility, so you can close this issue now.

New installation of pysnmp 4.x should resolve pyasn1 dependency to 0.5.1 by default and this issue won't appear again.
