pip-3.3 SSL verification error , mac OSX 10.5.8

问题

I am getting an error when trying to run pip-3.3 install numpy from the terminal in OSX 10.5.8

here is the error in question: could not fetch URL...:

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:547)>

as far as i can tell there is no information on this at all on google or anywhere else for that matter. So any information anyone can provide would be nice because installing packages by hand is a pain.

pip version:

pip 1.3.1 from /Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/pip-1.3.1-py3.3.egg (python 3.3)

The question I have is: Does anyone know what is causing this error and how I can fix it?

I can provide any other information you may need at request.

回答1:

Python versions for Mac OSX seem to be linked to a dated version of the SSL library, so the pypi SSL certificate fails some check.

The quick fix is to downgrade pip to a version that doesn't use SSL:

easy_install pip==1.2.1

Since your certificate is not correct, use https instead or import it from the browser or command line and specify for pip:

pip --cert my-root.pem <args>

^{If you've file in CER format, you need to convert it into PEM file.}
