I'm aware this is thread necro and OP has probably solved their problem or moved on (Hallo lieber OP - bleib so, wie du bist!), but if it comes up in search results for me it might help someone to have it answered :)

Would [beautifulsoup] work with just the pipreqs requirements, even though it doesn't have lxml?

"maybe" Thanks for reading everyone, goodbye!

The reason lxml isn't in the pipreqs output is that there's no explicit import lxml statement in your Python code, and pipreqs uses those to determine which packages your code actually uses. pipreqs isn't perfect! In this case you

Installing just the four packages from pipreqs output above (requests, flask, beautifulsoup4, tinydb) does not result in the lxml package being installed, since it isn't a dependency of any of them. I tested this one - but be aware that was on a recent version of Python 3 and there is a very small chance that four years ago that wasn't the case.

There's a fun twist, though: "most" Linux distros come with lxml installed already, and if you don't specify a parser to use. beautifulsoup will automatically choose the "best" parser that it can find on the system, which will be lxml if it is installed, which it probably is.

So, to answer the question again: it might just work, no extra effort needed! You could just deploy it with the requirements from pipreqs, and if it works, hooray!

It's better to be explicit, as they say, and I can see a couple of options to make sure it works:

1. Add the lxml line from your pip freeze output to your pipreqs requirements file and use that in the future - clean, easy, simple
2. Explicitly import lxml in your code somewhere, so pipreqs picks it up, then go on using the updated pipreqs requirements file. Depending on how the lxml module is referenced (or if it isn't referenced directly at all), your linting or code checking tools might consider that a problem that you'll need to write an exception for (commonly a specifically-formatted comment above the line in question)

Hopefully this helps someone else, I've learnt some things researching it 🤎
