Issues with pyinstaller and pyproj

Question

I'm trying to do an standalone application with pyinstaller. The executable has just build fine, but when I´m trying to do some operations with functions integrated on library pyproj, the executable crashes.

The script runs fine on Pycharm, so I think that the problem is that pyinstaller is not linking with some kind of library of pyproj.

May I have to do something special with spec file or another thing to specify pyproj on the standalone application built with pyinstaller?

This is the error that Ihave obtained:

Traceback (most recent call last):   File "<string>", line 6, in
<module>   File "C:\pyproj\build\main\out00-PYZ.pyz\pyproj", line 343,
in __new__   File "_proj.pyx", line 85, in _proj.Proj.__cinit__
(_proj.c:1190) 
RuntimeError: no system list, errno: 2

This is my "main.py"

 #!/usr/bin/env python
 # -*- coding: utf-8 -*-

 import pyproj 
 print pyproj.__version__ 
 p=pyproj.Proj(init='EPSG:4326')

Thanks in advance

Answer 1

The problem is that when using pyproj with PyInstaller, pyproj can not find the data files that are in the library folder.

The solution is to create a hook file, which will specify where the data files, so you can link them with our executable.

 hook-pyproj.py

 from PyInstaller.hooks.hookutils import collect_data_files
 datas = collect_data_files('pyproj')

The hook file can be located on "hooks" folder on Pyinstaller installation or using the order --additional-hooks-dir, specifying a folder in which will be located "hook-pyproj.py"

Just threading on the previous answer, since 2014 there has been some refactoring on PyInstaller and here is the correct import line for the hook file above :

from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files('pyproj')
