Min Version Check Should Handle Greater Than

[blink1073]

Description

If a dependency includes the > directive, we currently convert it to == here. This is technically incorrect, as we should instead technically find the next available version greater than that version and constrain to that version.

Reproduce

Depend on a >, see example failure.

Expected behavior

We get the correct min version.

Context

We can use the PyPI JSON API to get the right version.

import requests
data = requests.get('https://pypi.org/pypi/notebook/json').json()
versions = list(data['releases'])

• Operating System and version:
• Browser and version:
• JupyterLab version:
