Description

Download of http://youtu.be/NYhxaZXXwsg is not possible, see log above

[dstftw]

You are using an outdated version of youtube-dl. Read our FAQ if you have troubles updating.

[refinedcranberry]

found the issue. the install directions for pip on this page https://rg3.github.io/youtube-dl/download.html are wrong. they state to install youtube_dl instead of youtube-dl

[dstftw]

They are correct. PyPI package is called youtube_dl not youtube-dl.
