   Hi. Unfortunately I'm not able to spend time on this project these days. I appreciate the bug report but probably won't be able to fix it (at least not until I need this project next).

   Hi,

   I have the same problem. Is it possible that you have a typo in the script?

   

   Maybe it is diff_match_patch.diff_main instead of just diff_match_patch.diff?

   hi, for windows there isn't anything like pdf-diff we have to install poppler and visual c++ 14.0 requirement, and then it works,
   it is pip install diff_match_patch_python

   This issue is caused by a name collision issue between diff_match_patch and diff_match_patch_python. This program requires diff_match_patch-python, but diff_match_patch is installed by default on many systems. I uninstalled diff_match_patch using pip uninstall diff_match_patch and it works as intended.

   I'm on MacOS using a Conda environment with Python 3.9 installed.

   I'm not sure if this is an optimal solution, as diff_match_patch seems to be a frequently used library, but it works for me.

   It works for me if I change line 122 into diff_match_patch.diff_match_patch().diff_main

   Use

   pip uninstall diff_match_patch

   and

   pip install diff_match_patch_python
pip install pdf-diff

   It works like a charm without any issue. readjfb your suggestions helped a lot in a pdf comparison project.
