Python py2app IOError:[Errno 63]文件名太长：

我正在尝试在OS X 10.6和python 2.6上用py2app打包PySide应用程序

我发现的问题是，py2app似乎陷入了一个循环中，并递归地将相同的目录路径附加到其自身，然后它最终命中Python文件的时间过长，错误如上所述。下面是我得到的堆栈跟踪

检查路径是否有可能导致无限递归的符号链接。打开终端应用程序，然后键入以下内容：

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

后看到类似的情况：

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

---

那么这就是问题的根源。但是在脚本搜索文件的过程中，确实有某种原因导致了无限递归循环。

这个问题确实很老了，但我昨晚遇到了同样的问题并找到了解决方案。在我看来，这个问题是py2app试图在另一个文件夹中生成build和dist文件夹的副产品，该文件夹包含被构建代码引用的模块

由于py2app默认将build和dist文件夹放置在当前工作目录中，这意味着如果您在与代码引用的其他模块相同的工作目录中编写构建脚本，您会遇到麻烦

我通过使用py2app选项来强制在下面当前目录的父目录中创建build和dist目录，修复了这个问题，但是您可以将它们放在您选择的任何位置，并实现相同的效果：

#!/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')))

#/usr/bin/python
#-*-编码：utf-8-*-
导入py2app
导入系统
从distutils.core导入设置
从操作系统导入getcwd
从pathlib导入路径
sys.argv.append（'py2app'）
设置（应用程序=[''），
options=dict（py2app=dict（bdist_base=str（Path（getcwd（））.parent）
+'/build'，dist_dir=str（路径（getcwd（））.parent）+'/dist'））

hmm。。。在构建之前，那里没有任何文件。生成失败后，该文件夹中没有任何sim卡链接。。所以我不认为这是问题所在。。。谢谢你的回答。。
