py2app TypeError: dyld_find() got an unexpected keyword argument 'loader'

Question

我在使用 py2app 构建我的应用程序时遇到了困难。我可以使用此命令以别名模式构建它而不会出现问题：

python3.4 setup.py py2app -A

但是，当我尝试使用以下方法构建它时：

python3.4 setup.py py2app

我根据这篇文章的标题收到错误消息。根据我所做的研究，我认为这是 Pillow 的问题；但是我需要这个应用程序的枕头。 （除非我可以使用另一个模块来导入图像？？）。我也试过 cx_freeze 没有成功。

非常感谢任何帮助或指导。

完整回溯如下：

TypeError: dyld_find() got an unexpected keyword argument 'loader'

Answer 1

这是一个临时解决方案，它可能会破坏其他东西。我建议这样做是一个虚拟环境，这样你就不会弄乱你的常规包。这对我有用（virtenv 是我的虚拟环境的名称）

打开文件/virtenv/lib/python3.4/site-packages/macholib/dyld.py 并将loader_path 的每个实例替换为loader。现在保存并重试。

您可以对 macholib 进行猴子补丁，而不是在站点包中修改它。将以下文件放到 setup_py2app.py 所在目录，并在顶部添加import macholib_patch。

macholib_patch.py​​：

"""
Monkey-patch macholib to fix "dyld_find() got an unexpected keyword argument 'loader'".

Add 'import macholib_patch' to the top of set_py2app.py
"""

import macholib
#print("~"*60 + "macholib verion: "+macholib.__version__)
if macholib.__version__ <= "1.7":
    print("Applying macholib patch...")
    import macholib.dyld
    import macholib.MachOGraph
    dyld_find_1_7 = macholib.dyld.dyld_find
    def dyld_find(name, loader=None, **kwargs):
        #print("~"*60 + "calling alternate dyld_find")
        if loader is not None:
            kwargs['loader_path'] = loader
        return dyld_find_1_7(name, **kwargs)
    macholib.MachOGraph.dyld_find = dyld_find
