MoviePy錯誤：系統找不到指定的文件

Question

在Windows 10/Python 3.6.1/Sublime Text Editor 3中嘗試運行下面的示例代碼時，出現標題錯誤。我確定將我的MAGICK_HOME環境變量指向我手動安裝ImageMagick的位置。我確保只安裝了1個ImageMagick版本。我確保FFMPEG，Numpy，imageio，Decorator和tqdm都已安裝。

是的，文件「vidclip.mp4」存在。這裏所期望的行爲是根據github頁面上的示例簡單地裁剪視頻並將文本添加到中心，即簡單地成功運行代碼。

有誰知道什麼可能是錯的？從github

示例代碼：

from moviepy.editor import * 

video = VideoFileClip("vidclip.mp4").subclip(7,64) 

# Make the text. Many more options are available. 
txt_clip = (TextClip("Ken Block who?",fontsize=70,color='white') 
      .set_position('center') 
      .set_duration(10)) 

result = CompositeVideoClip([video, txt_clip]) # Overlay text on video 
result.write_videofile("vidclip_edited.webm",fps=25) # Many options...

    raise IOError(error) 
OSError: MoviePy Error: creation of None failed because of the following error: 

[WinError 2] The system cannot find the file specified. 

.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

發現這個問題。我沒有意識到它是命令，我指定的位置ffmpeg.exe和convert.exe在ImageMagick的文件。之後，我安裝MoviePy（按照該順序）。
