Error message

%s not supported

What it means

Raised as NotImplementedError in lizhi_download_playlist (src/you_get/extractors/lizhi.py:47). The playlist entrypoint extracts the radio id via match1(url, r'/(\d+)'); if the URL contains no /<digits> segment there is no radio station id to enumerate, so the URL is rejected.

Solutions

Use a canonical radio URL of the form http://www.lizhi.fm/<radio_id>/ (digits only), e.g. /549759/.
In scripts, validate with re.search(r'^https?://[^/]+/(\d+)/?', url) before calling.
For a single episode, use the two-segment form /<radio_id>/<audio_id>/ via lizhi_download instead.

Example fix

# before
lizhi_download_playlist('http://www.lizhi.fm/user/panjiayan')
# NotImplementedError: ... not supported

# after
lizhi_download_playlist('http://www.lizhi.fm/549759/')

Defensive patterns

Strategy: validation

Validate before calling

import re

def lizhi_playlist_url_valid(url):
    return re.search(r'/(\d+)', url) is not None

Try / catch

try:
    lizhi_download_playlist(url, output_dir)
except NotImplementedError as e:
    if str(e).endswith('not supported'):
        ask_user_for_radio_url()  # structural problem: no retry will help
    else:
        raise

Prevention

Only pass /<radio_id>/ URLs (digits) to the playlist entrypoint.
Beware the loose first-segment regex: profile URLs with digits can slip through and mis-parse.

When it happens

Trigger: Calling lizhi_download_playlist (or `you-get -l`) with a lizhi.fm URL containing no numeric path segment, e.g. 'http://www.lizhi.fm/' or a user/profile page like /user/abc — match1 returns None and the raise fires. Note the regex grabs the FIRST /digits segment, so a URL like /user/123/ also wrongly matches.

Common situations: Passing the site homepage or a profile URL instead of a radio URL; trailing-slash or uppercase-path variants that hide the digits.
