Django Fails to Start: Missing libtiff.so.5 Dependency in Virtual Environment

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm having trouble running my Django site. When I start the server with python manage.py runserver, I get an error about a missing shared object:

PYTHON
Exception in thread django-main-thread:
Traceback (most recent call last):
  ...
  File "/usr/home/sixpiece/env/lib/python3.11/site-packages/PIL/Image.py", line 82, in <module>
    from . import _imaging as core
ImportError: Shared object "libtiff.so.5" not found, required by "_imaging.cpython-311.so"

I’ve tried reinstalling packages with commands like:

BASH
(env) $ pip install --upgrade --force-reinstall --no-cache-dir `cat pipfreeze2.txt`

...but it shows errors such as:

BASH
cat: pipfreeze2.txt: No such file or directory
ERROR: You must give at least one requirement to install (see "pip help install")

The pip freeze output is attached below, and I also attempted reinstalling packages using a file named pipfreeze.txt, which resulted in errors. I’m sharing the full log via PrivateBin:

PrivateBin

The error appears while Django is trying to import models from the filer package, which in turn is trying to import PIL. The missing libtiff.so.5 is causing the failure. I'm not sure if this is a pip issue, a dependency issue, or something else.

Any help troubleshooting this dependency problem would be appreciated.

Django PIL/Pillow Dependency Issue

Your error is related to a missing system library that Pillow (PIL) depends on. The specific error shows:

ImportError: Shared object "libtiff.so.5" not found, required by "_imaging.cpython-311.so"

Root Cause

This is not a Python package issue but a system dependency problem. Pillow requires several system libraries to handle different image formats, and in this case, the TIFF library (libtiff.so.5) is missing on your system.

Solution

You need to install the required system libraries before Pillow can work properly. Depending on your operating system:

For Debian/Ubuntu:

BASH
sudo apt-get update
sudo apt-get install libtiff5-dev

For CentOS/RHEL/Fedora:

BASH
sudo yum install libtiff-devel

For FreeBSD (which appears to be your system based on the path `/usr/home/`):

BASH
pkg install libtiff

After installing the system dependency, you may need to reinstall Pillow:

BASH
pip uninstall pillow
pip install pillow

Note on Your pip Commands

The error with pipfreeze2.txt occurred because that file doesn't exist in your current directory. If you want to reinstall packages from a requirements file, make sure:

The file exists in your current directory
Use the correct syntax:

BASH
pip install -r pipfreeze.txt

Rather than:

BASH
pip install `cat pipfreeze.txt`

This should resolve your Django startup issue by providing the missing system library that Pillow requires.
