【问题描述】：

我正在使用 py2app 将 python 文件转换为应用程序并遇到此错误：

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):

  Reason: image not found

出错后，程序终止。程序中使用的所有图像都使用设置中的 data_files 包含在其中。我的代码有错误还是与 py2app 有关？

【问题讨论】：

这个问题解决了吗？现在遇到同样的问题。

标签： python py2app

【解决方案1】：

在你的

python setup.py py2app

或

python3 setup.py py2app

包括标志--packages=PIL

【解决方案2】：

为libpeg安装动态库

brew install libjpeg

应该解决这个问题，但是我仍然遇到了其他依赖项，例如 zlib 和 openjpeg。但是我自己编译 Pillow 是有效的。

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

总结如下：
