I was just trying to download a file on github (raw) using wget package (or curl) under Python2.7.11 and Windows 7. I got a certificate error as follows:
IOError: [Errno socket error] [ SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)
As an example, here is the code with a Python shell
import wget wget.download("https://valid_url_link")
This is not an issue with the tool wget since I got the same message in a windows shell with curl.
After quite a lot of time on stackoverflow and other resources, I finally found a solution on a github page (https://github.com/servo/servo/issues/5917). his may work for other systems so here is the solution that worked for me:
import wget import ssl ssl._create_default_https_context = ssl._create_unverified_context wgte.download("https://valid_url_link")
