python - 由于 Imagemagick 的错误，无法用 moviepy 编写文本剪辑

Question

我正在尝试将 TextClip 写入带有 moviepy 的视频中。它一直在工作，但是在我重新安装 ffmpeg 后，它就不再工作了(我不确定它是否导致它，但我提到它以防万一)。一些 TextClip 对象是纯空间。
我收到以下错误消息:

Traceback (most recent call last):
  File "C:\Users\USER\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\moviepy\video\VideoClip.py", line 1137, in __init__

    raise IOError(err.decode('utf8'))

During handling of the above exception, another exception occurred:

.

.This error can be due to the fact that ImageMagick is not installed on your computer, or (for Windows users) that you didn't specify the path to the ImageMagick binary in file conf.py, or that the path you specified is incorrect

我尝试了多种方法来解决问题，例如检查 config-default.py在moviepy安装目录下的文件，并且它指向的ImageMagick的路径没有错。我试图重新安装ImageMagick，它也没有用。我试图编辑 policy.xml ImageMagick 目录中的文件来自 none至 read|write ，但它也不起作用。任何人都可以提出其他可能的解决方案吗？

在 /etc/ImageMagick-6/policy.xml尝试完全注释掉以下行:<policy domain="path" rights="none" pattern="@*" />像这样:<!-- <policy domain="path" rights="none" pattern="@*" /> -->
