Installation fails due to conflicting pyasn1 version

[NeolithEra]

Hi, users are unable to run adminset due to dependency conflict with pyasn1 package. As shown in the following full dependency graph of adminset, adminset requires pyasn1==0.4.1，while pyasn1-modules==0.2.6 requires pyasn1>=0.4.6,<0.5.0.

According to pip’s “first found wins” installation strategy, pyasn1==0.4.1 is the actually installed version. However, pyasn1==0.4.1 does not satisfy pyasn1>=0.4.6,<0.5.0.

Solution

1. Loosen version constraint of pyasn1 to >=0.4.1.
2. Upgrade pyasn1 to ==0.4.6.
3. Add pyasn1-modules == 0.2.1 as a direct dependency in the requirement.txt

Which solution do you prefer, 1, 2 or 3?
