pyasn1 required version not found

[mohamed-osama-aboelkheir]

It is giving the below error

verify-scts google.com --short
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 666, in _build_master

pkg_resources.ContextualVersionConflict: (pyasn1 0.4.2 (/usr/local/lib/python3.6/site-packages), Requirement.parse('pyasn1<0.3.0,>=0.2.0'), {'ctutlz'})

During handling of the above exception, another exception occurred:

pkg_resources.DistributionNotFound: The 'pyasn1<0.3.0,>=0.2.0' distribution was not found and is required by ctutlz

It seems, the available version of pyasn1 is 0.4.2 which doesn't satisfy pyasn1<0.3.0,>=0.2.0.

Hello,
I am trying tu use your library on MacOS.
After installing the library using : "pip install ctultz", I run the command "verify-scts google.com --short"
Then I obtain the following error : "Segmentation Fault: 11"

Can you tell me what I have to do to solve this issue ?

Thank you
