Package installation inside git repo breaks about param

[jbednar]

| Installing param (pip install param) into a virtual environment that is inside a git repository fails with
| Exception: Cannot find any git version tags of format v_._
| This makes it difficult to install param as part of certain Jenkins CI workflows that make use of git + virtualenv.

Thanks for the report! Chris, I think you should go ahead with what we mentioned about ignoring all errors from version.py, just for cases like this where we don't quite know what environment it might have been placed into.

Jean-Luc, maybe it would be worth version.py catching this error and falling back to the declared version (plus perhaps "-dirty" or "-unknown" as a warning that we were unable to get version info).

We've got a fix now, thanks to Marco Elver and Jean-Luc Stevens; see #61

Can you please try installing version 786378d using pip's git support, with something like:

pip install git+https://github.com/ioam/param.git@786378da45e414f714ee4ab9f88c6cf89a551fee

Hi

I'm not sure it will work just yet - at least if any of our projects is being tested in this environment other than param. The 'reponame' argument needs to be set in the Version object for the other projects.

I'll fix this now.

I think to test the fix, I need to install from a source distribution, not via pip's git support.

Ah. We were hoping that you would test it so that we could make a new release confidently, but I guess we'll have to wing it and cross our fingers! We'll let you know when 1.2.1 is ready.

Ok, 1.2.1 is released and should fix this problem -- please reopen this issue if not!

This is fixed for me. Thanks!
