RegexMatchError: (\W[\'"]?t[\'"]?: ?[\'"](.+?)[\'"]) had zero matches

Tried adding the pattern into cipher.py to no effect… help please?

pytube==9.4.0, Python 3.7.1

It looks like comment out the related part in codes as a temploary solution works for me. # I'm not entirely sure whattrepresents. Looks to represent a # boolean. # t = regex_search( # r'\W[\'"]?t[\'"]?: ?[\'"](.+?)[\'"]', watch_html, # group=0, # ) params = OrderedDict([ ('video_id', video_id), ('el', '$el'), ('ps', 'default'), ('eurl', quote(watch_url)), ('hl', 'en_US'), # ('t', quote(t)), ])

Hi, Can you please elaborate on that? Thanks~

Go to extract.py line 116 and change the following to look like:

    else:
        # I'm not entirely sure what ``t`` represents. Looks to represent a
        # boolean.
        #t = regex_search(
        #    r'\W[\'"]?t[\'"]?: ?[\'"](.+?)[\'"]', watch_html,
        #    group=0,
        #)
        params = OrderedDict([
            ('video_id', video_id),
            ('el', '$el'),
            ('ps', 'default'),
            ('eurl', quote(watch_url)),
            ('hl', 'en_US'),
            #('t', quote(t)),
        ])

Notice that we’re just commenting out the stuff related to t. I don’t know why this works, and I’m guessing there are other bad side-effects, but it got me through my needs for the day.
