Description

pip install 'my-pkg > 0.2.dev136461' doesn't find any matching packages:

Looking in indexes: https://pypi.org/simple, https://example.com/repository/example/simple, https://example.com/repository/example-dev/simple
ERROR: Could not find a version that satisfies the requirement my-pkg>0.2.dev136461
ERROR: No matching distribution found for my-pkg>0.2.dev136461

pip install 'my-pkg >= 0.2.dev136461' (using ">=" instead of ">") finds and installs the package my_pkg-0.2.dev136483, which is strictly greater than the 0.2.dev136461 requested originally, so it should have been found by the original command.

Expected behavior

A package matching the criteria should have been found and installed.

How to Reproduce

I don't know if this bug is limited to dev versions of packages, or to private repositories; my steps to reproduce are:

1. Have a "dev version" of a package published in a private repo
2. Try to install as shown above
3. Package is not found.

Output

Shown above.
