See youtube-dl: Download Page.

To install it right away for all UNIX users (Linux, OS X, etc.), type:

sudo curl -L -o /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl 

If you do not have curl, you can alternatively use a recent wget:

sudo wget -O /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

You can also use pip:

sudo pip install --upgrade youtube_dl

The above steps will install latest version of youtube-dl that can be checked using youtube-dl --version. As of now the output of youtube-dl --version is:

2020.01.01
