After installing Tornado v4.3, SSL_CERTIFICATE_VERIFY_FAILED error

See original GitHub issue

Hello everyone.

I’m running a collection of Python scripts on my box, and one of them requires the pip package [Tornado](url http://www.tornadoweb.org/en/stable/).

After installing it with pip, Gspread now refuses to work and throws an error:

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:765)

Here is the relevant portion of the stack trace:

 File "/usr/lib/python2.7/site-packages/gspread/client.py", line 145, in open
    feed = self.get_spreadsheets_feed()
  File "/usr/lib/python2.7/site-packages/gspread/client.py", line 231, in get_spreadsheets_feed
    r = self.session.get(url)
  File "/usr/lib/python2.7/site-packages/gspread/httpsession.py", line 75, in get
    return self.request('GET', url, **kwargs)

This is totally unrelated to gspread, its a certificate verification issue on older python versions. I worked around this by downgrading/pinning ‘certifi’ package which is an indirect dependency. Try pip uninstall certifi && pip install certifi==2015.4.28, 2015.9.6, 2015.9.6.2 … one of those should work again Needless to say : this is a temporary workaround, the right solution is to upgrade Python to latest and making sure certificates are correctly validated

I’m closing this as the issue is not related to gspread.
