[Python] pyCurl won't retrieve https: site

MacBook Pro, macOS 15.3.2. Using PyCharm 2024.3.5, pyCurl 7.45.6, trying sample code from http://pycurl.io/docs/latest/quickstart.html, resulting error message "Protocol https not supported or disabled in libcurl". Changing URL to other sites doesn't help. When I run curl from the command line with --version option, https is listed as supported protocol, and I can retrieve multiple https: URLs from command line. Any help?

buffer = BytesIO()
c = pycurl.Curl()
c.setopt(c.URL, 'https://pycurl.io/')
c.setopt(c.WRITEDATA, buffer)
c.setopt(c.CAINFO, certifi.where())
c.setopt(c.VERBOSE, True)
c.perform()
c.close()


Output is:

Protocol https not supported or disabled in libcurl

Closing connection -1
