ModuleNotFoundError: No module named 'six'

[brentvollebregt]

google-auth 2.0.0 was released a few hours ago which google-auth-oauthlib depends on. The latest version 2.0.0 is now being used because the dependency google-auth>=1.0.0 is specified.

It appears google-auth 2.0.0 drops support for Python 2.7 and with this dropped the dependency of six which exists in 1.35.0 (latest compatible). This library (google-auth-oauthlib) requires six but does not declare it as a dependency - it was relying on a dependency having it as a dependency.

six needs to be added as a dependency to fix this.

Environment details

• OS type and version: Windows (originally discovered on ubuntu-18.04)
• Python version: 3.7
• pip version: 19.2.3
• google-auth-oauthlib version: 0.4.5

Steps to reproduce

1. Create a new Python virtual environment
2. Activate the virtual environment
3. Install google-auth-oauthlib: pip install google-auth-oauthlib
4. Execute the code example below

A positive result will not throw any exceptions in step 4 whereas it now does.

To prove it worked previously, extending the steps above:

1. Install the old google-auth library: pip install google-auth==1.35.0
2. Execute the code example below

Code example

from google_auth_oauthlib.flow import InstalledAppFlow

Based on the example import from here.

Thank you for the report! I believe we can remove the usage of six in this library. I've opened #146.
