moviepy封装问题

moviepy是个好东西，但封装起来就不那么友好了，先看报错：

脚本在没有封装的情况下可以正常使用，但是用pyinstaller -F 封装后运行就会直接报错："module ‘moviepy.audio.fx.all’ has no attribute ‘audio_fadein’“或者” module ‘moviepy.audio.fx.all’ has no attribute ‘audio_fadein’"然后闪退
这两个错是因为moviepy包下子包audio.fx.all、video.fx.all对应的目录moviepy\audio\fx\all、moviepy\video\fx\all下的包文件__init__.py中使用的是一种动态加载模块的模式加载包下的模块的，pyinstaller对这种模式不能处理

解决方法其实很简单：
首先把两个文件的for name in all: exec(“from …%s import %s” % (name, name))注释掉，
改为for name in all: print(“from moviepy.video.fx import %s” % (name))或者for name in all: print(“from moviepy.aideo.fx import %s” % (name))
手动运行一次，可以得到这么一串代码

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

将他们粘贴到原来的文件中，替换掉新加的两行代码即可
最终两个__init__.py文件内容如下：

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.aideo.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

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