Hello, I am getting an error when I try to create certificates using cert-tools, I am following the steps:

Traceback (most recent call last):
File “c:\python\lib\site-packages\pkg_resources_init_.py”, line 583, in build_master
ws.require(requires)
File "c:\python\lib\site-packages\pkg_resources_init.py", line 900, in require
needed = self.resolve(parse_requirements(requirements))
File “c:\python\lib\site-packages\pkg_resources_init_.py”, line 791, in resolve
raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (jsonschema 3.0.1 (c:\python\lib\site-packages), Requirement.parse(‘jsonschema<3.0.0,>=2.5.1’), {‘connexion’})

During handling of the above exception, another exception occurred:

run

pip install -r requirements.txt

Thanks, but it is still not working, it gives me: “Requirement already satisfied”, but when I try to create the template I get the same previous errors.

Do you think it is a problem with the python environment? I tried to follow this steps: https://github.com/blockchain-certificates/cert-issuer/blob/master/docs/virtualenv.md but I am not sure if I did it right…

initially i’m also facing too many issue. then i create separate venv with python3.7 it works well.

Thanks, I created a separate venv and that worked!
