This sounds like youtube-dl isn't available. Can you please install it and retry? (I have tested with <https://www.instagram.com/p/Bqxp0VSBgJg/> and it works here)

Installed youtube-dl, it works now, thank you. Should it be in requirements.txt?

It's only used for a couple extractors and an optional dependency so IMHO no (but it's documented in README).
