RaspbianPython3.9：ImportError：未安装 _imagingft C 模块

我正在try 运行一个简单的代码，使用PIL和Raspbian中的Python3.9中的自定义字体，但我无法通过此错误:

Traceback (most recent call last):
  File "/home/pi/python/src/mintest.py", line 2, in <module>
    font52 = ImageFont.truetype('fonts/Font.ttf', 52)
  File "/home/pi/.local/lib/python3.9/site-packages/PIL/ImageFont.py", line 878, in truetype
    return freetype(font)
  File "/home/pi/.local/lib/python3.9/site-packages/PIL/ImageFont.py", line 875, in freetype
    return FreeTypeFont(font, size, index, encoding, layout_engine)
  File "/home/pi/.local/lib/python3.9/site-packages/PIL/ImageFont.py", line 196, in __init__
    if core.HAVE_RAQM:
  File "/home/pi/.local/lib/python3.9/site-packages/PIL/ImageFont.py", line 70, in __getattr__
    raise ImportError("The _imagingft C module is not installed")
ImportError: The _imagingft C module is not installed

这是在Raspbian中再现错误所需的最小代码:

from PIL import ImageFont   
font52 = ImageFont.truetype('fonts/Font.ttf', 52)

这是我的系统信息

Output of python3 -m PIL

我已经try 了我在这里看到的所有答案.
