Installation

Installing youtube-dl (not the gem)

For youtube-dl.rb (the gem) to work, it needs youtube-dl (the tool) to be installed. By default the gem ships with a Python script and a Windows exe version of youtube-dl. The Windows exe includes the Python runtime, whereas the python script does not. It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is not platform specific.

The hard way

Using curl

sudo curl https://yt-dl.org/latest/youtube-dl -o /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

or with a recent wget

sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

Windows users can download a .exe file and place it in their home directory or any other location on their PATH.

The slightly easier way

OS X users can install youtube-dl with Homebrew.

brew install youtube-dl

If you have pip installed, you can do

[sudo] pip install youtube-dl

The METAL way
