SSL: CERTIFICATE_VERIFY_FAILED when trying to use the Google Assistant SDK

问题

When trying to authorize access to the Google Assistant API from my Raspberry Pi, I get an error of “SSLError” type, stating that the certificate verification has failed.

When I run:

python -m googlesamples.assistant.auth_helpers --client-secrets <path-to-secrets-file>

I get the following trace:

How can I fix this?

回答1:

One of the more likely issues for this to happen is your date and time being wrong. If your time/date is wrong, then try:

First change the date manually with the command date (see man page). For example:

sudo date -s "Mon Apr 24 13:30:00 PDT 2017"
If that works, but your time keeps desynchronizing with time, check out these instructions with several alternative solutions to ensure your time synchronizes properly.
