NameError: free variable 'url' referenced before assignment in enclosing scope

I am following the docs, and try this video:

url = "https://www.youtube.com/watch?v=RO014qcVkJc"

yt =pytube.YouTube(url)

   File "C:\Users\Moondra\AppData\Local\Programs\Python\Python36\lib\site-packages\pytube\mixins.py", line 41, in <listcomp>
if any([x in url for x in ['signature=', 'sig=']]):
NameError: free variable 'url' referenced before assignment in enclosing scope

Anyone understand what the problem is ?

I have upgraded to latest official version via pip

could you place your entire code/script here?

Let me see if I can find it.

could you place your entire code/script here?

That’s pretty much the entire script:

import pytube

url = "https://www.youtube.com/watch?v=RO014qcVkJc"

yt =pytube.YouTube(url)

Also:

>>> pytube.__version__
'9.5.1'
