I had the same error and solved the problem by running the program code below    install certifi py     sample script to install or update a set of default Root Certificates   for the ssl module   Uses the certificates provided by the certifi package          https   pypi python org pypi certifi  import os import os path import ssl import stat import subprocess import sys  STAT 0o775     stat S IRUSR   stat S IWUSR   stat S IXUSR                stat S IRGRP   stat S IWGRP   stat S IXGRP                stat S IROTH                  stat S IXOTH     def main        openssl dir  openssl cafile   os path split          ssl get default verify paths   openssl cafile       print  quot  -- pip install --upgrade certifi quot       subprocess check call  sys executable           quot -E quot    quot -s quot    quot -m quot    quot pip quot    quot install quot    quot --upgrade quot    quot certifi quot         import certifi        change working directory to the default SSL directory     os chdir openssl dir      relpath to certifi cafile   os path relpath certifi where        print  quot  -- removing any existing file or link quot       try          os remove openssl cafile      except FileNotFoundError          pass     print  quot  -- creating symlink to certifi certificate bundle quot       os symlink relpath to certifi cafile  openssl cafile      print  quot  -- setting permissions quot       os chmod openssl cafile  STAT 0o775      print  quot  -- update complete quot    if   name         main         main

I m a relative novice compared to all the experts on Stack Overflow   I have 2 versions of jupyter notebook running  one through a fresh Anaconda Navigator installation and one through        I think this is because Anaconda was installed as a local installation on my Mac  per Anaconda instructions     I already had python 3 7 installed  After that  I used my terminal to open jupyter notebook and I think that it put another version globally onto my Mac    However  I m not sure because I m just learning through trial and error   I did the terminal command    conda install -c anaconda certifi     as directed above  but it didn t work     My python 3 7 is installed on OS Catalina10 15 3 in     Library Python 3 7 site-packages AND   Library Python 3 7 lib python site-packages   The certificate is at      Library Python 3 7 lib python site-packages certifi-2019 11 28 dist-info   I tried to find the Install Certificate command     but couldn t find it through looking through the file structures   not in Applications   not in links above   I finally installed it by finding it through Spotlight  as someone suggested above   And it double clicked automatically and installed ANOTHER certificate in the same folder as      Library Python 3 7 lib python site-packages    NONE of the above solved anything for me   I still got the same error     So  I solved the problem by    closing my jupyter notebook  opening Anaconda Navigator  opening jupyter notebook through the Navigator GUI  instead of through Terminal    opening my notebook and running the code    I can t tell you why this worked   But it solved the problem for me   I just want to save someone the hassle next time  If someone can tell my why it worked  that would be terrific   I didn t try the other terminal commands because of the 2 versions of jupyter notebook that I knew were a problem  I just don t know how to fix that

Use requests library  Try this solution  or just add https    before the URL   import requests from bs4 import BeautifulSoup import re  pages   set   def getLinks pageUrl       global pages     html   requests get  http   en wikipedia org  pageUrl  verify False  text     bsObj   BeautifulSoup html      for link in bsObj findAll  a   href re compile     wiki               if  href  in link attrs              if link attrs  href   not in pages                   We have encountered a new page                 newPage   link attrs  href                   print newPage                  pages add newPage                  getLinks newPage  getLinks       Check if this works for you
