/usr/bin/env: 'python': No such file or directory

Description

The script at https://yt-dl.org/downloads/latest/youtube_dl use ‘python’ binary which is not existing at Ubuntu 20.04 and this introduces a bug that the script cannot find the ‘python’ binary. The only python binaries by default are ‘python3, python3.8, python3-futurize, python3-pasteurize’. So simple symbolic link can solve the issue.

Since there is no support for “python 2” anymore. I think this bug exist in many OS’s and further investigation is needed.

^ The recurrence, the fact ppl can’t google, and the fact distros are being dicks are exactly the reasons why something has to be done.

But that’ll be problematic cuz the way the mentioned “binary” is created you can’t target Py2 and 3 with the same line, and you can’t have multiple shebangs, and you can’t have any code before the shebang.

^ The only way to circumvent that is a db of default Python versions (2 or 3, no need for stricter) for the script which creates the “binary”. Which, to be blunt, is gonna be an impossible cat-and-mouse.

^ And don’t get me started on the CI using separate distros running [near-]identical scripts.

If you are under a Node.js project, consider using youtube-dl-exec since it checks for python version before installing the dependency, throwing an error if the right Python version is not found.
