I'm attempting to install Netbox on a brand new fresh Raspberry Pi 4 but am getting a Pillow dependency error. My Google-Fu has failed me, and I only found one other post about this over on reddit for which there was no resolution to the Python dependency problem, only sad abandonment.

Everything goes through and installs just fine without error until this:

$ python3 manage.py migrate
SystemCheckError: System check identified some issues:

ERRORS:
extras.ImageAttachment.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
        HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "pip install Pillow".

Pillow is installed, but via pip3, not pip (likely a clue?):

$ pip3 install Pillow
Looking in indexes: https://pypi.org/simple,
Requirement already satisfied: Pillow==7.0.0 in /usr/local/lib/python3.7/dist-packages (from -r requirements.txt (line 18)) (7.0.0)

and:

>>> help("modules Pillow")

Here is a list of modules whose name or summary contains 'Pillow'.
If there are any, enter a module name to get more help.

PIL - Pillow (Fork of the Python Imaging Library)
PIL.DdsImagePlugin - A Pillow loader for .dds files (S3TC-compressed aka DXTC)
PIL.FtexImagePlugin - A Pillow loader for .ftc and .ftu files (FTEX)

Some additional info:

$ cat /sys/firmware/devicetree/base/model;echo
Raspberry Pi 4 Model B Rev 1.1
$ uname -a
Linux raspberrypi 4.19.93-v7l+ #1290 SMP Fri Jan 10 16:45:11 GMT 2020 armv7l GNU/Linux
$ python3 --version
Python 3.7.3

Anyone care to share any ideas?

Does this import successfully?

$ python3 manage.py nbshell
>>> import PIL

Also, did you run `pip3 install -r requirements.txt` to ensure all of the dependencies are up to date?

Thanks for the reply, Jeremy.

Yeah, I ran `pip3 install -r requirements.txt` and everything comes back OK without exception.  Running now gives "Requirement already satisfied" for all.

Attempting to run `python3 manage.py nbshell` results in the same, unfortunately.

$ python3 manage.py nbshell
SystemCheckError: System check identified some issues:

ImageAttachment is part of NetBox, not Pillow, so that's fine.

Try:

$ pip uninstall PIL
$ pip uninstall Pillow
$ pip install Pillow

To clean out any previous installations.

FWIW, in a Python shell, when I run `help("modules Pillow")` and `help("modules PIL"), I notice that neither output includes "ImageAttachment" or "ImageField".  If either/or are supposed to be explicitly stated in that output, it's not.

I'm actively looking myself rather than just relying on answers here.  If I happen to find it, I'll post the solution.  In the meantime, thanks for any assistance.

Could this be an issue with whatever libraries are installed on the OS (Not sure what OS you can run on RaspPi, maybe just whatever embedded OS it has)?

Re: ImageAttachment, excellent.

I had found the `pip uninstall PIL; pip uninstall Pillow; pip install Pillow` steps and ran through them early on... didn't seem to help.

It's running a varient of Debian called Raspbian, optimized for the ARM hardware.  It very much is likely due to some OS library or missing link somewhere... I just don't know what, and can't find any reference to it.  Details on getting Netbox on a Raspberry are slim-to-none out here in the world.  Gonna keep trying, though.

What about with pip3 rather than pip?

Are you logging in to RPi as a non-root user, then doing "sudo"? Try "sudo -H pip3 ..." instead.

Same result.  I tried both pip3 and pip, logged in as root and using sudo... current theory is that there's some missing library or link on Raspbian that I'm trying to track down.

I wonder if it's missing a required system library. Try installing the libraries listed here:

sudo apt-get install libjpeg-dev zlib1g-dev libfreetype6-dev liblcms1-dev libopenjp2-7 libtiff5
