Py2App PIL Image error when launching app

问题

I am using py2app to convert a python file into an application and am running into this error:

Traceback (most recent call last):
  File "/Users/MYUSER/PycharmProjects/webstuff/BotTest/dist/ws1.app/Contents/Resources/__boot__.py", line 87, in _recipes_pil_prescript
    import Image
ModuleNotFoundError: No module named 'Image'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/MYUSER/PycharmProjects/webstuff/BotTest/dist/ws1.app/Contents/Resources/__boot__.py", line 132, in <module>

  Reason: image not found

After the error, the program is terminated. All images used in the program are included in it using data_files in the setup. Is there an error with my code or is it something to do with py2app?

回答1:

In your

python setup.py py2app

python3 setup.py py2app

include the flag --packages=PIL

回答2:

Installing the dynamic library for libpeg

brew install libjpeg

should solve this, I still ran into other dependencies such as zlib and openjpeg however. But compiling Pillow myself worked.

git clone git@github.com:python-pillow/Pillow.git
brew install jpeg
brew install openjpeg
brew install zlib
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
cd Pillow
python setup.py install

Here's the summary:
