Python36 enum34 issue

I’m attempting to build a project using the Python36 interpreter, and there’s a package that calling for enum34, and I can’t figure out how to prevent it from being installed. Any suggestion regarding which of the built in packages are calling for this or how to prevent it from being installed?

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    }
}

    url './repo'
    layout "pattern", {

      artifact "[organisation]/[module]/[revision]/[artifact]-[revision](-[classifier]).[ext]"
      m2compatible = true
    }
  }
  pyGradlePyPi()
}

python.cli.generateCompletions = true

Using an earlier forcedVersion did the trick. Thanks.

python {
    testDir = file("tests")
    details.pythonVersion = '3.6'
    details.systemPythonInterpreter = '/usr/local/bin/python3.6'
    forceVersion('pypi', 'flake8', '3.2.1')

}

Workarounds:

• Try putting in the python { ... } closure: forceVersion("pypi", "flake8", "3.2.1") if you can use lower version of flake8. It seems that versions below 3.3.0 did not have that dependency.
• Alternatively, use older version of pygradle that did not update to flake8-3.6.0.

Notice that there’s nothing wrong here with the flake8 itself. It declares the dependency conditionally in its Python package metadata. It’s the Ivy format used by Gradle that has no notion of conditional dependencies that’s at fault. So, the full solution would be porting our plugins mentioned above.

I hope this helps you.
