Python cx_Freeze 名称 __file__ 未定义

Question

我有一个 python 脚本，它从互联网上获取图像，下载它，设置为桌面背景并在几分钟后更新。问题很可能是 cx_Freeze 不包括 os 模块，因为具有绝对路径的相同代码可以正常工作。我的代码也可以完美运行，直到它通过冻结。当我通过控制台加载、从 IDLE 运行或双击它时，它会在冻结之前工作。每当我运行冻结的文件时，我都会收到错误消息（如果我使用 setup.py 或 cxfreeze file.py:

C:\Python33\Scripts>C:\Python33\Scripts\dist\desktopchanger.exe
Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\cx_Freeze\initscripts\Console3.py", line 2
7, in <module>
    exec(code, m.__dict__)
  File "C:\Python33\desktopchanger.pyw", line 7, in <module>
    dir = path.dirname(__file__)
NameError: name '__file__' is not defined

我的代码

import pythoncom
from urllib import request
from win32com.shell import shell, shellcon
from time import sleep
from os import path

dir = path.dirname(__file__) #get dierctory script is in
startpath = str(path.join(dir+'/bg/bg.jpg')) #add /bg/bg.jpg to path of script

pathtoimg=[]
for char in startpath:
    if char != "/":
        pathtoimg.append(char)  #replace / with \, necessary for setting bg
    else:
        pathtoimg.append("\\")

newpath = "".join(pathtoimg)

def get_image():
    f = open(newpath, 'wb') #open .....\bg\bg.jpg
    f.write(request.urlopen('http://blablabl.com/totale.jpg? i=0.387725243344903').read()) #get image from web and write over previous file
    f.close()

while 1:
    get_image()


#sets background below
    iad = pythoncom.CoCreateInstance(shell.CLSID_ActiveDesktop, None,
          pythoncom.CLSCTX_INPROC_SERVER, shell.IID_IActiveDesktop)
    iad.SetWallpaper(newpath, 0)
    iad.ApplyChanges(shellcon.AD_APPLY_ALL)
    sleep(60)

setup.py

from cx_Freeze import setup, Executable

exe=Executable(
     script="desktop_changer_with_url2.py",
     base="Win32Gui",
     icon="icon.ico"
     )

includes = ["os","urllib","time","pythoncom","win32com.shell"]

setup(
    name = "Heindl Webcam als Desktop" , 
    version = "1",
    description = "eowjbadpoaäbaaplabipösdbjosdobsaboösac bjcaähpdaöbökabidsidsöds.", 
    executables = [exe],

你的旧线路：

dir = path.dirname(__file__)

用以下行替换它以运行冻结或解冻的脚本：

if getattr(sys, 'frozen', False):
    # frozen
    dir_ = os.path.dirname(sys.executable)
else:
    # unfrozen
    dir_ = os.path.dirname(os.path.realpath(__file__))

使用 python 3.3.4 测试。在win32上
