Gunicorn failed to start as it fails to identify the version of a package

问题

While gunicorn is attempting to run flask server, the following error is shown:

Traceback (most recent call last):
  File "/root/.local/share/virtualenvs/customer-account-automation-gLS21FFx/lib/python3.7/site-packages/pbr/version.py", line 442, in _get_version_from_pkg_resources
    provider = pkg_resources.get_provider(requirement)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 344, in get_provider
    return working_set.find(moduleOrReq) or require(str(moduleOrReq))[0]
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 892, in require
    needed = self.resolve(parse_requirements(requirements))

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'jira' distribution was not found and is required by the application

During handling of the above exception, another exception occurred:

Exception: Versioning for this project requires either an sdist tarball, or access to an upstream git repository. It's also possible that there is a mismatch between the package name in setup.cfg and the argument given to pbr.version.VersionInfo. Project name jira was given, but was not able to be found.

Here you find jira module installed

(customer) root@jsd:~/flask# pip freeze --all
...
Flask==1.1.2
gunicorn==20.0.4
jira==2.0.0
....

The weird thing is that when running flask run instead, it works and never complains, so I am thinking there is a problem with gunicorn.

The command I run gunicorn with is:

gunicorn --bind jsd.tv:5000 wsgi:customer_account_automation/app --pythonpath /root/.local/share/virtualenvs/customer-account-automation-gLS21FFx/lib/python3.7/site-packages

Any ideas what could be the issue here?
