Is this was @sontek was getting at in #65?

Happens with pip-review as well.

Traceback (most recent call last):
  File "/home/edos/projects/accounts/venv/bin/pip-review", line 269, in <module>
    main()
  File "/home/edos/projects/accounts/venv/bin/pip-review", line 229, in main
    installed = list(get_installed_pkgs(local=args.local))
  File "/home/edos/projects/accounts/venv/bin/pip-review", line 147, in get_installed_pkgs
    name, version = line.split('==')
ValueError: need more than 1 value to unpack

pip freeze gives:

-f /home/edos/.pip/repo/
...

Seems like we should be able to simply ignore these entries? Not sure when they occur in pip freeze output, but happy to accept a patch that fixes this.

I belive, @coagulant already solved this issue: coagulant@2b1f0bc. But seems, he forgot to make a pull request.

[edoshor]

It happens to me when I use find-links in my global pip.conf

[coagulant]

@svetlyak40wt dependency_links is not the same as find-links. Anyway pip no longer respects dependency links by default since 1.5, so I don't think it's worth merging as is.

I am getting the same error in pip-review when pip freeze outputs -f file:///home/simon/.wheelhouse.

Simply ignoring any line starting with '-f' solved the issue. I don't know about side effects though.

I'm closing old issues. If this issue still applies and requires my attention, I ask you kindly to re-open it or file a new issue. Thanks.

For reference: #93 is about a similar issue for -e.
