Downloading playlists from a channel into folders

[miacaba]

Hello,

I'm trying to get a channel playlist to download into folders. I tried using the following command but got this error:

youtube-dl --youtube-skip-dash-manifest -f 18 "https://www.youtube.com/user/OUlearn/playlists" --get-filename -o "/%(playlist)s/%(playlist_index)s-%(title)s.%(ext)s" --restrict-filenames

WARNING: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)> (caused by URLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)'),))

What is wrong with this? or what is the proper command? I would like to get them in 480p if possible, with each playlist in its own folder. Thank you.
