Install failure with pip 20 and setuptools 46 about streaming-form-data

[siddhantgoel]

Alright, I just uploaded 1.7.1 and this version seems to install fine with a plain pip install streaming-form-data.

Ended up replacing the poetry build backend with a setup.py file and had to drop support for Python 3.5. 🤷‍♂️

Thanks for the report! I haven't had a look at PEP 517 and haven't yet had a chance to spend time debugging this. I hope I can find some time over the weekend though.

If poetry really is the problem (which would be a shame since I really liked working with it), I could imagine switching the build process to the "barebones" setup that the Cython documentation recommends. That should most likely solve this issue.

I'm still using poetry on other pure-python projects, so it's not all that bad. 🙂 Thanks for the heads up about the README.

I understand why you choose poetry, it's an interesting option for complex packaging. But it seems it is not yet prod-ready on some points / quite unstable yet (just check https://github.com/python-poetry/poetry/issues). If I remember well from my digging, you're not the only case of having some troubles with poetry and the latest pip regarding building environments and paths. Maybe there could be a solution in some regards to poetry configuration / setuptools configuration, honestly it's a shot in the dark.

A solution would be to use gitlab actions, or whatever pipeline you have access to, to upload some built versions to pypi for the most common architectures. I know it defeats a bit the point behind opting for poetry, but it may ask less digging and/or work on your side. Maybe

Anyway. I'm not sure I have more time to dig around and try to find the root cause, but if I do, I'll forward the information. Thanks for answering so quickly, good luck !

thanks @guzmud

pip install poetry && pip install --no-build-isolation streaming-form-data

worked for me.

pip install poetry && pip install --no-build-isolation streaming-form-data worked for me!

Having the same issue. Workaround works fine but doesn't work well with requirements files.
Subscribing to the thread :)

Well, I'm sorry you had to throw poetry away, all my sympathies.

Just so you know, it's working perfectly now, though you may want to edit your README, installation part, to specify at least build-essential is required.

If someone wants to test the proper install in a lightweight environment, feel free to check with :
docker run --rm python:3.8-slim-buster sh -c "apt-get update && apt-get install -y build-essential && pip install streaming-form-data"

Anyway, thank you @siddhantgoel , keep up the good work (I let you close this issue).
