KeyError: 'dislike_count' in pafy

[snyamwong]

I think the API no longer returns dislike counts (given the recent Youtube fiasco with removing dislikes...), and now pafy will throw an exception when playing a video.

Traceback (most recent call last):

Issue / Suggestion

The easiest fix is to go into site-packages/pafy/backend_youtube_dl.py and comment out this line

#self._dislikes = self._ydl_info['dislike_count']

It looks like pafy already has a pull request for this, which takes the same approach: mps-youtube/pafy#305

It looks like pafy already has a pull request for this, which takes the same approach: mps-youtube/pafy#305

But is it going to make in the repo and a release any time soon? This repo hasn't seen any commits in a while, is there some fork of it that is maintained?

[yardenac]

@Ciliane there's a more-maintained fork at https://github.com/otisdog8/termitube/ but they haven't merged their PR yet either

[Sophira]

@yardenac That repo is a fork of mps-youtube, but the edits need to take place in both that and pafy, which are maintained as separate projects. The pull request I linked to is the one for the pafy repo. So far as I know, there isn't a fork for that one yet.

As for termitube, it hasn't had any commits for about two and a half months either, and the project doesn't have an Issues tab so it's difficult to report issues with it. Hopefully they'll accept the pull request, but as I say, pafy needs to be updated as well.
