老猿前面有篇文章《moviepy应用pyinstaller打包后执行报错AttributeError: module audio/video.fx.all has no attribute ‘fadein’、crop》，今天居然发现有人原文照抄还获了很多个赞，而老猿的原文居然还没有赞。抄袭文章链接为：https://www.pythonheidong.com/blog/article/314732/。并且这篇文章今天仔细核对了一下，还有错误，在此更正一下。

原文解决办法部分，“如针对audio.fx.all，在Python中手工执行如下代码：”

import pkgutil

import moviepy.video.fx as fx

__all__ = [name for _, name, _ in pkgutil.iter_modules(fx.__path__) if name != "all"]
for name in __all__: 
	print("from  moviepy.video.fx import %s" % (name))

实际上这个地方应该这样处理：

>>> import pkgutil
>>> import moviepy.audio.fx as fx
>>> __all__ = [name for _, name, _ in pkgutil.iter_modules(
    fx.__path__) if name != "all"]
>>> for name in __all__: 
	print("from  moviepy.audio.fx import %s" % (name))

	
from  moviepy.audio.fx import audio_fadein
from  moviepy.audio.fx import audio_fadeout
from  moviepy.audio.fx import audio_left_right
from  moviepy.audio.fx import audio_loop
from  moviepy.audio.fx import audio_normalize
from  moviepy.audio.fx import volumex
>>> 

将上面的输出语句拷贝到audio.fx.all的__init__.py，替换被注释的2行代码即可。如movipy1.03的版本中，拷贝到audio.fx.all的__init__.py文件后，该文件内容为如下：

"""
Loads all the fx !
Usage:
import moviepy.audio.fx.all as afx
audio_clip = afx.volume_x(some_clip, .5)
"""

import pkgutil

import moviepy.audio.fx as fx

__all__ = [name for _, name, _ in pkgutil.iter_modules(
    fx.__path__) if name != "all"]

#for name in __all__:
    exec("from ..%s import %s" % (name, name))
#for name in __all__: 
#	print("from  moviepy.audio.fx import %s" % (name))

from  moviepy.audio.fx import audio_fadein
from  moviepy.audio.fx import audio_fadeout
from  moviepy.audio.fx import audio_left_right
from  moviepy.audio.fx import audio_loop
from  moviepy.audio.fx import audio_normalize
from  moviepy.audio.fx import volumex
