启动应用程序时出现Py2App PIL图像错误

Question

我正在使用py2app将一个Python文件转换为应用程序，但遇到了以下错误：

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>

  Referenced from: /Users/MYUSER/PycharmProjects/webstuff/BotTest/dist/ws1.app/Contents/Resources/lib/python3.7/lib-dynload/PIL/_imaging.so
  Reason: image not found

在出现错误后，程序将被终止。程序中使用的所有图像都是通过设置中的data_files包含的。我的代码有错误吗？还是与py2app有关？

这个问题解决了吗？我现在也遇到了同样的问题。 - Ted Cost

Answer 1

在您的

python setup.py py2app

或者

python3 setup.py py2app

包括标志--packages=PIL

- Ryan

Answer 2

安装动态库libpeg。

brew install libjpeg

虽然应该解决了这个问题，但我仍然遇到了其他依赖项，例如zlib和openjpeg。但是自己编译Pillow可以解决这个问题。

git clone [e-mail]: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

这里是摘要：
