ImportError: cannot import name 'opentype' on new installation

Question

I've just created a Google Cloud compute engine, installed google-cloud package with both pip and pip3, and I'm experiencing the following error when launching a script with python3

    from google.cloud import bigquery
  File "/usr/local/lib/python3.5/dist-packages/google/cloud/bigquery/__init__.py", line 35, 
in <module>
    from google.cloud.bigquery.client import Client
  File "/usr/local/lib/python3.5/dist-packages/google/cloud/bigquery/client.py", line 36, in
 <module>

(more traceback lines..)

    from pyasn1_modules.rfc2459 import Certificate
  File "/usr/local/lib/python3.5/dist-packages/pyasn1_modules/rfc2459.py", line 20, in <modu
le>
    from pyasn1.type import opentype
ImportError: cannot import name 'opentype'

On the compute engine the following packages are installed:

pyasn1==0.1.9
pyasn1-modules==0.2.1
google-cloud==0.30.0
google-cloud-bigquery==0.28.0

Which can be the problem here?

Answer 1

Posting my solution in case it helps someone else - this fixed it for me:

pip install --upgrade google-auth-oauthlib

It looks like you have an issue with pyasn1, so you could try installing a newer version (the latest is 0.4.2), or even reinstalling it manually with:

sudo apt-get --reinstall install python-pyasn1 python-pyasn1-modules

---

And if you are inside a virtualenv, use instead:

pip install pyasn1 pyasn1-modules
