I have tried upgrading the pyasn and pyasn1_modules library, but to no avail.

pip list | grep "google"

google-api-core (1.2.1)
google-api-python-client (1.7.4)
google-auth (1.5.0)
google-auth-httplib2 (0.0.3)
google-cloud-bigquery (1.3.0)
google-cloud-core (0.28.1)
google-resumable-media (0.3.1)
googleapis-common-protos (1.5.3)

pip list | grep "pyasn"

pyasn (1.6.0b1)
pyasn1 (0.4.3)
pyasn1-modules (0.2.2)

Hey,

Interesting. Since pyasn1 and pyasn1_modules are dependencies of a dependency (oauth2client), my first thought is that you may be reusing a virtual environment that already has an outdated versions of those libraries and is causing trouble. An alternative that would have the same effect is if you have them installed at the system level. I looked around a bit and it seems like that's typically been the case when others have had this issue. A couple things that would be useful:

1. Try creating a new virtual environment, make sure that pip freeze doesn't return either of those pyasn1 modules, and then install datasheets in there. I have a hunch that would solve it.

2. Follow the advice in either of these GitHub issues: first, second. Both basically amount to upgrading those packages within your existing environment.

In either case, I'd be interested to see the output of a pip freeze | grep pyasn1 both in the offending environment and in one you can get working. This issue hasn't come up before, but it may be prudent for us to put a minimum version for these transitive dependencies just to avoid this.

Hope that helps!

Hey @immuntasir, given that there hasn't been any more activity on this issue in last couple months I'm gonna close it on the assumption that the above resolved the problem. If it didn't, please let me know!
