Not trying to defend Python, but it's not hard to make it work like JS without virtualenv:

    pip install -r requirements.txt --target=python_modules
Then to run:

    PYTHONPATH=python_modules python myscript.py
This will keep all the dependencies in the local "python_modules" directory. I've used this on a custom SaaS platform, and it worked quite well.



Also, that's more or less what virtualenv does. It would be nice if this was default, but IIRC it's coming.


Thanks for that! I am tired of messing with conda, virtualenv, etc. and since I use simple Makefiles to build and run most of my code, I can easily stick with the standard latest stable version Python installation when using your trick.

EDIT: a question: when I have to use Python, I like to break up my code into small libraries and make wheel files for my own use. How do you handle your own libraries? Do you have one special local directory that you build wheel files to and then reference that library in your requirements.txt files?

We didn't build wheels. We had a centralized git host (Gitlab, but any of them works) with all our libraries, and just added the git url (git+https://...) to the requirements.txt


Even better, thanks.
