我正在尝试在 OS X 10.6 上用 python 2.6 和 py2app 打包一个 PySide 应用。

我遇到的问题是，py2app 似乎陷入了一个循环，不断地把同一个目录路径加到自己里面，最后导致出现了 Python 文件过长的 IOError 错误。下面是我得到的错误堆栈信息：

省略...（很多行都是和上面和下面的一样）

继续省略...

下面是我的 setup.py 文件：

Usage:
    python setup.py py2app
"""

from setuptools import setup

APP = ['gui.py']
DATA_FILES = []
OPTIONS = {}
#OPTIONS = {'argv_emulation': True}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
    includes=['PySide']
)
文件路径 os x setup.py 应用打包 pyside py2app IOError

检查一下路径中是否有符号链接，这些链接可能会导致无限循环。打开终端应用程序，然后输入以下命令：

ls -l /Users/mlakewood/Documents/Programming/DataWrangler/build/bdist.macosx-10.6-universal/python2.6-standalone/app/collect

如果在执行 ls -l 后看到类似下面的内容：

/Users/mlakewood/Documents/Programming/DataWrangler/build/bdist.macosx-10.6-universal/python2.6-standalone/app/collect -> ../../../../../build/

那么这就是导致问题的原因。不过，肯定还有其他东西在脚本查找文件的过程中造成了无限递归循环。

这个问题其实很老了，但我昨晚遇到了同样的问题，并找到了一个解决办法。对我来说，问题的根源在于py2app试图在一个包含代码所引用模块的文件夹里生成build和dist文件夹。

因为py2app默认会把build和dist文件夹放在当前工作目录下，所以如果你在和其他模块同一个工作目录里写构建脚本，那就麻烦了。

我通过使用py2app的选项，强制让build和dist文件夹在当前目录的上级目录中创建，当然你也可以把它们放在任何你想要的位置，效果是一样的：

#!/usr/bin/python
# -*- coding: utf-8 -*-
import py2app
import sys
from distutils.core import setup
from os import getcwd
from pathlib import Path

sys.argv.append('py2app')
setup(app=['<your_code.py>'],
      options=dict(py2app=dict(bdist_base=str(Path(getcwd()).parent)
      + '/build', dist_dir=str(Path(getcwd()).parent) + '/dist')))
