ERROR: Failed building wheel for brotli - Dash subprocess

[Guillaume0789]

Hello everyone!
I have a problem during the docker build with the dash. From what I read, the sub-dependency with brotli seems to be broken.

Sry if the solution is obvious, i'm new in the develop family.
Thank's a lot !

Describe your context
Here the requirements.txt :
gunicorn
python-dotenv
dash
dash-bootstrap-components
pandas
rasterstats
fiona

Describe the bug
When i build the docker env, an error is raise. The install of the brotli dependence stop. Few days ago (october 21) it worked but not today.
I tried to force an dash v2.6.1 install but it doesn't change anythings.

Hello @Guillaume0789.

Can you please provide your docker file?

[Guillaume0789]

Hello @nickmelnikov82 ,

Of course, here it is :
`FROM python:3-slim

RUN apt-get update && apt-get install -y inotify-tools

WORKDIR /app

ENV PYTHONDONTWRITEBYTECODE 1

RUN pip install --upgrade pip
COPY ./requirements.txt /app/requirements.txt
RUN pip install -r requirements.txt

COPY ./web /app/ ``

brotli has not published wheels for python 3.11, in the meantime new wheels are published, the dependency needs to be compiled manually, for that you need to install the python-dev packages for python 3.11.

Same for #2286

[Guillaume0789]

Ok i see.
Thank you for the quick answer @T4rk1n !

[Guillaume0789]

To close this issue.
I have changed this line in docker file :
'FROM python:3.10-slim'
Now it works !

Thanks guys for the advices !
