我收到 MoviePy 错误：由于以下错误，创建 None 失败，如何解决此问题

Question

这是我的代码：

import cv2
import numpy as np
from PIL import ImageFont, ImageDraw, Image
from moviepy.editor import VideoFileClip, TextClip, 
CompositeVideoClip

os.environ["IMAGEMAGICK_BINARY"] = r"C:/Program Files/ImageMagick-7.1.1-Q16-HDRI/magick.exe"

def create_video_with_typewriter_effect(text, output_filename, fontsize=30, video_fps=30):
 # Load your video
 video = VideoFileClip("D:/video.mp4")
 video = video.subclip(0, 2)  # Trim the video if needed

 # Get video dimensions
 video_width = video.w
 video_height = video.h
 video_size = (video_width, video_height)

 # Create a TextClip for the entire text
 font = 'Arial-Bold'
 text_clip = TextClip(text, fontsize=fontsize, font=font, color='white')

 # Calculate the number of frames for the typing effect
 num_frames = int(video.duration * video_fps)

 # Initialize a list to store each frame
 frames = []

 # Create individual frames for the typing effect
 for frame_idx in range(num_frames):
    frame = np.zeros((video_height, video_width, 3), dtype=np.uint8)
    frame_pil = Image.fromarray(frame)
    draw = ImageDraw.Draw(frame_pil)

    current_text = text[:int(len(text) * frame_idx / num_frames)]
    text_clip = TextClip(current_text, fontsize=fontsize, font=font, color='white')
    text_clip = text_clip.set_duration(1 / video_fps)
    text_clip = text_clip.set_position(("center", "center"))
    text_clip = text_clip.set_start(frame_idx / video_fps)
    frames.append(text_clip.get_frame(frame_idx / video_fps))

# Composite the frames over the video
typewriter_video = CompositeVideoClip([video.set_duration(video.duration), *frames])

# Write the final video to the output file
typewriter_video.write_videofile(output_filename, codec='libx264', fps=video_fps)


text = "Ancient Ruins and Storied History Journey through Sri Lanka's Cultural Triangle"
output_filename = "D:/output_video.mp4"
create_video_with_typewriter_effect(text, output_filename)

我得到的错误： OSError：MoviePy 错误：由于以下错误，创建 None 失败： Convert.exe：预期标签

@C:\Users\hp\AppData\Local\Temp\tmprpxltnkj.txt' @ error/annotate.c/GetMultilineTypeMetrics/804. convert.exe: no images defined 

PNG32:C:\Users\hp\AppData\Local\Temp mpaf7s7kpu.png' @ error/convert.c/ConvertImageCommand/3362。 。 此错误可能是由于您的计算机上未安装 ImageMagick，或者（对于 Windows 用户）您没有在文件 conf.py 中指定 ImageMagick 二进制文件的路径，或者您指定的路径不正确

确认您已经安装了ImageMagick。你还应该设置“IMAGEMAGICK_BINARY”的环境
