"Successfully installed package-version" text has version of uninstalled editable package, instead of installed version

[jmoldow]

• Pip version: 8.1.2
• Python version: 3.5.0
• Operating System: OS X Yosemite Version 10.10.5

Description:

1. Clone a repo, check it out to a git tag for a PyPI release.
2. pip install -e <path>
3. pip install a different version from PyPI
4. Last line of output reads "Successfully installed package-uninstalled_version"

Expected last line of output to read "Successfully installed package-installed_version"

In the example below, I installed a local checkout of requests v2.0.0, then installed requests v2.10.0 from PyPI, and observed "Successfully installed requests-2.0.0" at the end.

NOTE: There is no functionality problem. The old version does get uninstalled, and the new version does get installed. The only thing wrong is the text.

What I've run:

~ $ mkdir repos && git clone https://github.com/kennethreitz/requests.git repos/requests
~ $ cd repos/requests && git checkout v2.0.0 && cd
~ $ virtualenv env35-test

This seems to be a duplicate of #2382 which has a proposed fix in #3612. The problem appears to stem from pkg_resources.

If and when #3612 is re-filed against master, it should be updated to reference both #2382 and this bug.

Hopefully fixed by #3723
