Struggling with Externally Managed Environment Setuptools: How to Properly Configure and Use It? - deepJump99 - 06-08-2024

Hey everyone,

So I’ve been trying to wrap my head around this *externally managed environment setuptools* thing, and honestly, it’s been a bit of a headache. 😅

I’m working in an environment where everything’s managed externally, and I’m not entirely sure how to properly configure setuptools for it. Like, do I need to tweak the `setup.py` file differently? Or is there some magic flag I’m missing?

Also, how do you even *use* setuptools in an externally managed environment without breaking stuff? I keep running into dependency conflicts, and it’s driving me nuts.

Anyone else dealt with this before? Any tips or tricks would be super appreciated!

Thanks in advance! 🙏

Hey! I feel your pain with the externally managed environment setuptools setup. It can be a real headache, especially with dependency conflicts.

One thing that worked for me was using `--no-deps` flag when installing packages. This avoids pulling in dependencies that might clash with your externally managed environment. Also, check out `pip`'s `--ignore-installed` flag if you're dealing with conflicts.

For setup.py, I’d recommend keeping it minimal and letting the external system handle the heavy lifting. Maybe try `find_packages()` to auto-detect your packages instead of hardcoding them.

Hope this helps!

Oh man, externally managed environment setuptools is such a niche but frustrating topic. I’ve been there!

One tool that saved me was `pip-tools`. It helps manage dependencies more cleanly by generating a requirements.txt with resolved versions. You can then use that in your setup.py to avoid conflicts.

Also, have you looked into `pyproject.toml`? It’s becoming the new standard for Python packaging and might simplify your setup.py woes.

Good luck!

Hey! Dealing with externally managed environment setuptools can be tricky, but here’s a quick tip:

Make sure your setup.py is using `install_requires` instead of `requirements.txt`. This way, setuptools can better handle dependencies without stepping on the toes of your external environment.

Also, if you’re running into conflicts, try isolating your build environment with `virtualenv` or `conda`. It’s not perfect, but it can help avoid some of the mess.

Let us know how it goes!

Ugh, externally managed environment setuptools is such a pain. I’ve been there too!

One thing that helped me was using `pip`'s `--prefix` option to install packages in a specific directory. This way, you can avoid messing with the external environment while still using setuptools.

Also, check out `wheel` for building your packages. It’s way cleaner than dealing with eggs or source distributions.

Good luck, and don’t let it drive you too nuts!

Hey! I’ve had my fair share of struggles with externally managed environment setuptools.

One thing that might help is using `setuptools_scm` for version management. It integrates well with external environments and can save you from hardcoding versions in setup.py.

Also, if you’re dealing with dependency conflicts, try using `pip`'s `--constraint` flag to lock down versions. It’s not perfect, but it can help.

Hope this gives you some ideas!

Oh, externally managed environment setuptools... what a nightmare!

I’d recommend checking out `poetry` as an alternative to setuptools. It’s designed to handle dependencies and packaging in a more modern way, and it plays nicer with external environments.

Also, if you’re stuck with setuptools, try using `extras_require` in setup.py to separate optional dependencies. It can help reduce conflicts.

Good luck, and hang in there!

Wow, thanks so much for all the suggestions, everyone! I didn’t expect so many helpful replies.

I tried using `--no-deps` and `--ignore-installed` like some of you suggested, and it definitely helped reduce the conflicts. Also, `pip-tools` looks super promising—I’m gonna give that a shot next.

Quick question though: for those of you using `pyproject.toml`, do you still need a setup.py file, or can you completely replace it? I’m curious if it’s worth switching over.

Thanks again, you all rock! 🙌
