身份验证失败：[Errno 1] _ssl.c：510：错误：14090086：SSL例程：SSL3_GET_SERVER_CERTIFICATE：证书验证失败

Question

I am using python 2.7.6, Django 1.8 and python-social-auth. While trying to authenticate via googleoauth2 I am getting this error. The traceback is attached. I have tried these -

sudo apt-get install ca-certificates
sudo apt-get install ntpdate

But even then its not working.

Traceback:

Answer 1

pip2.7 install --upgrade httplib2 

上面的解决方案对我有用

Answer 2

I faced the same issue. Try doing pip install urllib3[secure] , urllib3 doesn't have certs by default so you have to do this. This is also shown here --> https://urllib3.readthedocs.org/en/latest/security.html#security

Answer 3

you can install the following package

python -m pip install  pyopenssl pyasn1 ndg-httpsclient

I got the same issue resolved by installing the above library.
