You have to install reportlabs as specified in the dependencies.

I can't confirm that it's the solution to the problem. For example, I run an M1 Max processor, and I get the same error. Suffice to say that reportlabs and the other dependencies are installed. I tried to install the dependencies manually in case something went wrong, but everything was already there. Version 2.7.2 works fine, as @xobed mentioned. Maybe something about the ARM architecture of the M1 chips version 2.8.0 or a dependency doesn't like. I remember scipy having a similar problem where installing on an M1 machine wasn't possible.

The error occurred during the migration process. Here are all packages installed on my venv for my Django project:

asgiref==3.4.1
bleach==4.1.0
cssselect2==0.4.1

I think this issue should be re-opened due to what seems like a bug in reportlab, which seems to be discussed in these threads:

• [reportlab-users] Symbol not found in flat namespace when running on macOS 12.0.1
• [reportlab-users] Fwd: Symbol not found in flat namespace when running on macOS 12.0.1

I was able to reproduce this in a fresh Python 3.9 virtual environment on an M1 MacBook Air:

% python3 -m venv venv-reportlab && source venv-reportlab/bin/activate

% python3 -V
Python 3.9.6

% pip install -U setuptools pip wheel

% pip install easy-thumbnails
...
Successfully installed asgiref-3.5.0 cssselect2-0.4.1 django-4.0.2 easy-thumbnails-2.8.1 lxml-4.8.0 svglib-1.2.1

% python3 -c "from easy_thumbnails.VIL.Image import load"

A workaround is to install reportlab from source:

% pip freeze | xargs pip uninstall -y

% pip install --no-binary reportlab easy-thumbnails
...
  Running setup.py install for reportlab ... done
