docxcompose与PyInstaller打包后出现FileNotFoundError问题求助

Root Cause #

PyInstaller doesn’t automatically package the template files (custom.xml) that docxcompose depends on. When the compiled EXE runs, it extracts files to a temporary directory but misses these template assets, leading to the error.

Solutions #

1. Use PyInstaller Command Line with --add-data #

First, locate the templates folder in your docxcompose installation. Run this code in Python to get the exact path:

import docxcompose
import os
print(os.path.join(os.path.dirname(docxcompose.__file__), "templates"))

Then use the path in your PyInstaller command:

• Windows:

  pyinstaller --add-data "C:\path\to\docxcompose\templates\*;docxcompose/templates/" your_script.py
  

• macOS/Linux:

  pyinstaller --add-data "/path/to/docxcompose/templates/*:docxcompose/templates/" your_script.py
  

2. Use a PyInstaller Spec File #

1. Generate a spec file for your project:

   pyinstaller --name your_app_name your_script.py
   

2. Open the generated your_app_name.spec file, find the datas list, and add the template directory path:

   datas=[
       # Replace the first path with your actual docxcompose templates directory
       ('C:\\path\\to\\docxcompose\\templates\\', 'docxcompose/templates/'),
   ],
   

3. Recompile using the spec file:

   pyinstaller your_app_name.spec
   

Verification #

After compiling, run the EXE again. The custom.xml file will now be present in the temporary directory (C:\Users\*user*\AppData\Local\Temp\_MEIXXXXXX\docxcompose\templates\), resolving the FileNotFoundError.
