It does work on my local pc just not when deploying I am also running the same python version on both railway and my pc

Brody•2mo ago

what version of python do you use locally?

DylZ•2mo ago

Im using 3.12.0

Brody•2mo ago

nixpacks doesnt support python 3.12 yet, so instead add 3.11 to a runtime.txt file

DylZ•2mo ago

Ohhh, good to know I just pushed with 3.11 now I still get the same error

python-magic-bin 0.4.14 if from 2017

DylZ•2mo ago

Is there a way to apt-get something? Ill try without making it 0.4.14

Brody•2mo ago

yeah, but may i ask why? i would highly recommend using something pure python thats more up to date

DylZ•2mo ago

On the python-magic github it says on Debian/Ubuntu to use sudo apt-get install libmagic1, i just didnt know if i could apt-get something on railway so i was trying to do it without using it I couldtn find anything because i had tried but there just wasnt anything up to date I am using something from 7 years ago right now and it is just too outdated so I was hoping to get something a little newer

Brody•2mo ago

the -bin version would include libmagic1 im now thinking python-magic-bin is not compatible with python 3.8+

DylZ•2mo ago

I dont know if i even have a python version that old on my local pc And it does work on my local pc I will check again to make sure Yeha it works on my pc using python 3.12

Brody•2mo ago

its already installed, so of course it will work lol

DylZ•2mo ago

Oh wait im tired lmao It does install on my localpc

Brody•2mo ago

its already installed

DylZ•2mo ago

I just tried uninstalling and installing agian with --no-cache-dir and it did work

Brody•2mo ago

what os are you using?

DylZ•2mo ago

Windows 10 so its obv a lot different then ubuntu but idk

Brody•2mo ago

might not support ubuntu

DylZ•2mo ago

Im guessing not but i did read that python-magic can be installed with apt-get install on some random website so would i be able to test that? or is that not doable? Oh it seems like its for python 2.7 though so nevermind Im not very good with linux so I dont know

Brody•2mo ago

use this https://pypi.org/project/python-magic/ and then place this nixpacks.toml file in your project -

[phases.setup]
  aptPkgs = ['...', 'libmagic1']

[phases.setup]
  aptPkgs = ['...', 'libmagic1']

Okay let me give that a try Im getting an Import error now,

File "/app/Routes/fileUploads.py", line 10, in <module>

import magic

File "/opt/venv/lib/python3.11/site-packages/magic/__init__.py", line 209, in <module>

libmagic = loader.load_lib()

^^^^^^^^^^^^^^^^^

File "/opt/venv/lib/python3.11/site-packages/magic/loader.py", line 49, in load_lib

raise ImportError('failed to find libmagic.  Check your installation')

ImportError: failed to find libmagic.  Check your installation

Brody•2mo ago

is this a web app of some kind?

DylZ•2mo ago

Yeah Im using the magic lib for a file uplaoder

Brody•2mo ago

flask? fastapi?

DylZ•2mo ago

fastapi

Brody•2mo ago

why arent you using gunicorn?

DylZ•2mo ago

I wish i had an answer lol pretty much got lazy and im jsut debugging atm I will swap to it though Is gunicorn like way better than uvicorn? I havent looked into that much at all to be honest

Brody•2mo ago

haha im tired too, i meant uvicorn

DylZ•2mo ago

ohh I just do it in my python code Because of my debugging on my pc it was jsut quicker to run it lol so pretty much just because im lazy

Brody•2mo ago

the fastapi constructor is named app right?

DylZ•2mo ago

Yeah

DylZ•2mo ago

Heres how i start it Would it be better to start it using the start command, or is this just fine?

Solution

Brody•2mo ago

nixpacks is being difficult, we are moving to a Dockerfile, add this as a Dockerfile to your project -

FROM python:3.12

ENV PYTHONUNBUFFERED=1
ENV PIP_DISABLE_PIP_VERSION_CHECK=1

RUN apt-get update && apt-get install -y --no-install-recommends \
    gcc \
    libmagic1

WORKDIR /app

COPY requirements.txt ./

RUN pip install -r requirements.txt

COPY . ./

CMD uvicorn main:app --host 0.0.0.0 --port $PORT

FROM python:3.12

ENV PYTHONUNBUFFERED=1
ENV PIP_DISABLE_PIP_VERSION_CHECK=1

RUN apt-get update && apt-get install -y --no-install-recommends \
    gcc \
    libmagic1

WORKDIR /app

COPY requirements.txt ./

RUN pip install -r requirements.txt

COPY . ./

CMD uvicorn main:app --host 0.0.0.0 --port $PORT

(you can delete the nixpacks.toml file)

DylZ•2mo ago

Okay, ive never toucher dockerfiles so i dont knwo them well. What do i name the file? Just Dockerfile?

Brody•2mo ago

correct

DylZ•2mo ago

alright

Brody•2mo ago

as you can see, its just a set of commands that setup the project, super simple stuff

DylZ•2mo ago

Yeah they seem pretty helpful maybe ill look into them some more

Brody•2mo ago

not as finicky as nixpacks

DylZ•2mo ago

It started Let me test it out but it should work The code ran so that seems like a good sign to me Thank you!! Ive been trying to figure that out for days now lol

Brody•2mo ago

no problem!

DylZ•2mo ago

Have a good night!

Brody•2mo ago

Dockerfiles are always the answer you too!!

DylZ•2mo ago

Will use them in the future
