Quick workaround that I found: delete the file google_appengine/lib/cacerts/cacerts.txt from your installed SDK.

Starting from the GoogleAppEngineLauncher:

GoogleAppEngineLauncher/Contents/Resources/GoogleAppEngineDefault.bundle/Content‌​s/Resources/google_appengine/lib/cacerts/cacerts.txt

EDIT #

as of google app engine SDK 1.8.1 this file as been renamed to
urlfetch_cacerts.txt. Still in the same directory and removing it
still fixes the problem.

Compact answer, current as of January 2014 (just survived an SDK update):

rm file /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts/urlfetch_cacerts.txt

or …

cd /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/cacerts/
rm urlfetch_cacerts.txt

and everything runs smoothly again.

And you better delete “cacerts.txt” (in the same directory), too. Otherwise the sdk command line tools will throw exceptions, too 🙁

FYI: if you are on a Mac running Mavericks, this error might be due to using python 2.7.6 or lower, which has a known bug that causes this error.

For example, you would get a similar error by simply trying to get any SSL page:

pip install requests
python

>>> import requests
>>> requests.get("https://github.com")

The above would yield the same SSL cert errors. In this case, none of the gcloud (Google cloud SDK) commands work.

Upgrade to python 2.7.8 (or newer 2.7.X) to solve the problem (worked for me).

Upgrading Python from 2.7.3 to 2.7.9 fixed it for me. I’m on Mac OS X 10.6.8 (Snow Leopard).
