SSL module is not available error in python3 Windows 11


When running the FlightRadarAPI on python 3.12, windows 11 I'm getting an ImportError: Can't connect to HTTPS URL because the SSL module is not available.

ImportError: Can't connect to HTTPS URL because the SSL module is not available.

To add to the complexity, the code works when run normally, the error only happens while running it via PyScript (a combination of python and html)


Solution

  • The SSL module is unvendored by default in Pyodide, but can be installed in PyScript using:

    <py-config>
      packages=['ssl']
    </py-config>
    

    Once you install it, however, note that SSL generally doesn't function in browser, since socket is not available in the browser. See also this GitHub Issue for more discussion.
