Py2app包含lxml

Question

我在OSX Yosemite上用py2app构建了一个应用程序，它使用lxml。构建的应用程序在OSX 10.8.5上抛出错误。下面是我在py2app中使用的setup.py文件：

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup

APP = ['iTunes_Upload_App_V6.2.py']
DATA_FILES = []
OPTIONS = {
    'iconfile':'AppleLogo.icns',
    'packages' : ['wx', 'lxml'],
    'plist': {'CFBundleShortVersionString':'6.2',}
}

setup(
    app=APP,
    name='iTunes_Upload_App_V6.2',
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

这是我在没有安装额外模块或软件的OSX 10.8.5机器上运行它时收到的错误。

-------------------
Application Error!

我可以在10.8.5系统上不安装任何其他东西的情况下使其工作吗？

更新:我也尝试了这个setup.py，仍然不起作用：

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup

APP = ['iTunes_Upload_App_V6.2.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True,
                   'packages' : ['lxml'],
                   'frameworks' : ['/usr/local/libxml2-2.7.2/lib/libxml2.2.7.2.dylib'],
                   'iconfile':'AppleLogo.icns',
                   'plist': {'CFBundleShortVersionString':'6.2',}
                   }

setup(
    app=APP,
    name='iTunes_Upload_App_V6.2',
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

更新: Ans这里是我使用的lxml版本：

>>> from lxml import etree
>>> etree.LXML_VERSION
(3, 3, 5, 0)

更新:刚刚将lxml更新到版本(3，4，1，0)，但仍然存在相同的问题。

我使用的是10.8.5，看起来安装的libxml2确实不包含这个符号。nm -g /usr/lib/libxml2.2.dylib | grep xmlBufContent是空的。苹果可能会在Yosemite上发布一个更新的版本。你能(从技术上和法律上)将libxml2与你的应用捆绑在一起吗？
