Pipenv Doesn't Correctly Resolve Dependencies

[Kurt-von-Laven]

Issue description

pipenv fails to install prospector 1.3.1, which pip successfully installs.

Expected result

I expected pipenv to successfully install prospector without errors by falling back on earlier versions of flake8 once detecting a dependency constraint conflict on pycodestyle.

Actual result

Pipenv complained of a dependency constraint conflict on pycodestyle that blocked installation, and never attempted an earlier version of flake8.

Workaround

Install flake8 3.8.3 first, and then install prospector. flake8 3.8.3 is the last version of flake8 that doesn't depend on pycodestyle >=2.7.0.

[franzhaas]

Hi,

I encountered a similar issue, with jupyter books.

My solution is to use pip for dependency resolution, but pip for everything else...

See #4777

Best regards
Franz

[matteius]

I suspect you are using an older version of pip which is less strict with the resolver, when I try installing it with pipenv it is clearly an issue with the prospector==1.3.1 package.

((venv) ) bash-3.2$ pipenv install --dev prospector==1.3.1
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

[franzhaas]

I thought current versions of pipenv use pip for resolving. I therefore expect that it can or cannot solve the same situations as pip.

Am I mistaken here? Does it come with its own pip which may be different to the one accessible by the comandline?

[matteius]

@franzhaas The output I had above was for pipenv version 2021.5.29 which fails to resolve the dependencies. The newest version of pipenv 2021.11.23 does in fact resolve the dependencies for that package though.

Pipenv doesn't come with its own version of pip but it does come with a lot of other vendor and patched vendor packages including piptools and requirementslib. It seems the newest version 2021.11.23 does use pip commands as the resolver, but not the prior version 2021.5.29

Thanks for the clarification!
