Experienced same error. In cipher.py replace the regexs in pattern in get_initial_function_name with: r'\bc\s*&&\s*d\.set$[^,]+\s*,\s*\([^)]*$\s*\(\s*(?P<sig>[a-zA-Z0-9$]+)\('.

FYI if you want to install the latest source directly from github using pip, type this in your command line:

pip install git+https://github.com/nficano/pytube.git

File “/usr/local/lib/python3.5/site-packages/pytube/helpers.py”, line 41, in regex_search .format(pattern=p), pytube.exceptions.RegexMatchError: regex pattern (yt.akamaized.net/)\s*||\s*.?\sc\s*&&\sd.set([^,]+\s,\s*(?P<sig>[a-zA-Z0-9$]+)() had zero matches

Same error but it occurs intermittently

@yelosheng It doesn’t look like you updated your regex. See my comment above or pull the most recent version of the lib.
