Description

When trying to download Youtube videos, I'm getting this error:

WARNING: Unable to extract video title 
ERROR: This video is unavailable.

I went to update Youtube-dl by executing:
sudo pip install --upgrade youtube_dl

Which throws:

WARNING: The directory '/Users/[my name]/Library/Caches/pip' or its parent directory is not owned or is not writable by the current user. The cache has been disabled. Check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
Requirement already up-to-date: youtube_dl in ./.local/lib/python3.6/site-packages (2020.5.3)

So even though I'm told that 'Requirement up-to-date' for version 2020.5.3, running this command tells me my version is out of date:

youtube-dl --version
2019.06.08

What am I missing here?

Most likely you have multiple youtube-dl instances installed.

How do I remedy this? I am new to Python and package managers. Thank you.

@psrpsrpsrpsr Either uninstall youtube-dl from APT or from PIP.

Apt: sudo apt remove youtube-dl

You just need to remove one. Follow the instructions in the README for pip.
