获取&quot；TypeError：每当尝试对Moviepy中的剪辑运行WRITE_VIDEOFILE时，必须为实数，而不是NoneType&QOOT；

Getting quot;TypeError: must be real number, not NoneTypequot; whenever trying to run write_videofile to a clip in moviepy(获取quot；TypeError：每当尝试对Moviepy中的剪辑运行WRITE_VIDEOFILE时，必须为实数，而不是NoneTypeQOOT；)

问题描述

示例代码：

from moviepy.editor import *
clip = VideoFileClip('video.mp4')
clip.write_videofile('video2.mp4', fps=30)

在显示以下消息后，表示正在构建和编写视频

Moviepy - Building video video2.mp4.
Moviepy - Writing video video2.mp4

出现以下错误消息：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:UsersUserAnaconda3libsite-packagesdecorator.py", line 232, in fun
    return caller(func, *(extras + args), **kw)

    '-r', '%.02f' % fps,
TypeError: must be real number, not NoneType

每当我尝试在Moviepy中对任何类型的剪辑执行write_videofile时，都会出现这种情况。奇怪的是，昨天完全相同的代码对我起作用了，但今天突然不再起作用了。是否有任何建议是什么原因以及如何解决此问题？

推荐答案

尝试升级您的电影包

pip install moviepy --upgrade

我在1.0.0版本中遇到了同样的问题。升级到1.0.3已修复该问题。
