py2app IOError：[Errno 63]文件名太長：

我試圖使用python 2.6在OS X 10.6上使用py2app封裝PySide應用程序。py2app IOError：[Errno 63]文件名太長：

問題我得到它，它似乎像py2app被困在一個循環和遞歸追加到它的自我相同的目錄路徑，然後它最終命中Python文件太長IOError如上。下面是堆棧跟蹤我得到

檢查路徑是否有可能導致無限遞歸的任何符號鏈接。打開終端應用程序，輸入：

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

如果你看到這樣的事情做ls -l後：

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

然後那是什麼原因造成的問題。但是，在腳本搜索文件的方式中肯定會導致無限遞歸循環。

嗯......在構建之前，沒有任何文件在那裏。構建失敗後，沒有任何SIM卡鏈接在該文件夾..所以我不*認爲*多數民衆贊成在這個問題...謝謝你的答案.. –

這個問題真的很老，但我昨晚遇到了同樣的問題，並找到了解決方案。原來，對我來說，這個問題是py2app的副產品試圖生成構建和DIS包含的代碼正在修建中引用模塊的另一個文件夾內噸文件夾。

由於py2app默認放置構建和DIST文件夾在當前工作目錄，這意味着你就麻煩了，如果你在相同的工作目錄編寫構建腳本爲其它模塊由您的代碼引用。

我用py2app選項，以迫使構建和DIST在低於當前目錄的父目錄中創建目錄解決了這一問題，但你可以把它們無論你選擇，並實現同樣的事情：

#!/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')))
