Downloading YouTube videos with yt-dlp will require the installation of a JavaScript runtime such as Deno.

YT-DLP is a command line tool that allows you to download content from the Internet. Although it is a command line tool, the basic command is very simple: just enter 'yt-dlp' followed by the public URL of a video or other content, making it extremely easy to use. For detailed instructions on how to use YT-DLP, please see the link below.
Summary of how to use 'yt-dlp' which allows you to download movies such as YouTube and Niconico videos with the highest image quality and high sound quality, and age-restricted movies can also be downloaded in one go - GIGAZINE
YT-DLP supports many streaming sites, including YouTube, Niconico, X, and Vimeo, and each site maintains its own content extraction tool (extractor). The difficulty of developing an extractor varies depending on the streaming site, and the development costs for YouTube's extractor are particularly high.
Below is a snippet of the YouTube extractor code . The YouTube extractor contains a complex set of regular expressions to identify the functions required to extract content. Every time YouTube makes a change, the regular expressions need to be rewritten. This rewriting process is costly, requiring multiple maintainers to stop all other work and spend two to three days on the job.
Recent YouTube updates have made regular expression-based support difficult in terms of both cost and security. In addition, YouTube will soon require the generation of PO tokens when referencing content, but the existing mechanism makes it difficult to support PO tokens. As a result, the development team switched to a JavaScript-based approach. Because this JavaScript code is too complex to be executed by the JavaScript interpreter built into yt-dlp , it is now necessary to install a separate JavaScript runtime such as Deno to download YouTube videos.
At present, it is stated that Deno is supported as well as Node.js and Bun , but the development team recommends using Deno because it is easy to set up even for users who are not familiar with technology. In fact, Deno can be installed on various operating systems, including Windows, with a single command , and can also be used by simply placing a single binary in any location.
At the time of writing, development is underway to enable the use of JavaScript runtimes such as Deno. The development team will release more information, including the minimum required version of Deno, once it is ready.
