py2app IOError：[Errno 63]文件名太长：

我试图使用python 2.6在OS X 10.6上使用py2app封装PySide应用程序。py2app IOError：[Errno 63]文件名太长：

问题我得到它，它似乎像py2app被困在一个循环和递归追加到它的自我相同的目录路径，然后它最终命中Python文件太长IOError如上。下面是堆栈跟踪我得到

检查路径是否有可能导致无限递归的任何符号链接。打开终端应用程序，输入：

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

如果你看到这样的事情做ls -l后：

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

然后那是什么原因造成的问题。但是，在脚本搜索文件的方式中肯定会导致无限递归循环。

嗯......在构建之前，没有任何文件在那里。构建失败后，没有任何SIM卡链接在该文件夹..所以我不*认为*多数民众赞成在这个问题...谢谢你的答案.. –

这个问题真的很老，但我昨晚遇到了同样的问题，并找到了解决方案。原来，对我来说，这个问题是py2app的副产品试图生成构建和DIS包含的代码正在修建中引用模块的另一个文件夹内吨文件夹。

由于py2app默认放置构建和DIST文件夹在当前工作目录，这意味着你就麻烦了，如果你在相同的工作目录编写构建脚本为其它模块由您的代码引用。

我用py2app选项，以迫使构建和DIST在低于当前目录的父目录中创建目录解决了这一问题，但你可以把它们无论你选择，并实现同样的事情：

#!/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')))
