Gsutil: Running gsutil fails after updating via pip

[yodax]

Yesterday I've update gsutil and since then it fails from the command line with the following stack trace:

$ gsutil

This is installed on FreeBSD 11.1 via pip. It was upgrade via pip install --upgrade gsutil.

The same setup has worked just fine for many years now. (, wel not on FreeBSD 11.1 since that isn't out for years, but on the same install)

It's probably one of the dependencies giving a problem, I think.

It's almost weekend so no rush of course. :smile:

BTW 'google-apitools==0.5.15' has a fix for this... but gsutil is pinned to version 0.5.3.
Alternatively you need to pin six package.

Thanks! I pinnend six to the previous version as a temporary fix.

Released v4.28 today, which pins to v0.5.16 of apitools. Marking as fixed.

[yodax]

Thanks!

For anyone else with the issue, pip install six==1.10.0 is the version of six. I needed to use pip2, for Python2.7 but that's dependant on your own Python. pip or pip3 might work too.
