HTTPError and TypeError with pip-check installed by pip3

[Nairwolf]

Hi,

I am using pip-check installed with pip3. I'm running currently this command pip-check -c /usr/bin/pip3 and I receive this :

Loading package versions...
Exception:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_internal/cli/base_command.py", line 143, in main
    status = self.run(options, args)

    return _get_html_page(link, session=self.session)

    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://pypi.org/simple/unattended-upgrades/

And effectively the link https://pypi.org/simple/unattended-upgrades/ returns a 404 error. So is there an error from the Pypi side, or is related to pip-check ?

Moreover, if I'm running pip-check -c /usr/bin/pip3 -U, I receive this :

Loading package versions...
Exception:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_internal/cli/base_command.py", line 143, in main
    status = self.run(options, args)

    packages = self.get_outdated(packages, options)
  File "/usr/lib/python3/dist-packages/pip/_internal/commands/list.py", line 149, in get_outdated
    dist for dist in self.iter_packages_latest_infos(packages, options)
  File "/usr/lib/python3/dist-packages/pip/_internal/commands/list.py", line 150, in <listcomp>
    if dist.latest_version > dist.parsed_version
TypeError: '>' not supported between instances of 'Version' and 'Version'

Is it related to my installation ? With pip3, I've installed pip-check 2.5.2. I don't have any pip binary installed, only pip3 which is under /usr/bin/pip3 and in my PATH.

Is it related to the option -c ?

Your -c looks correct to me. The traceback is raised by pip, not pip-check.

  File "/usr/lib/python3/dist-packages/pip/_internal/commands/list.py", line 150, in <listcomp>
    if dist.latest_version > dist.parsed_version
TypeError: '>' not supported between instances of 'Version' and 'Version'

Does this still happen when you update pip itself?

pypa/pip#5429 looks related.

The issue is fixed since pip 19.1 (commit 8ef3283, specifically). ...
