Imagefont truetype 无法打开资源

Question

打不开。 媒体文件夹中的 ttf 文件但它的工作 Localserver 但现在项目托管到 pythonanywhere

class SmartRCBack(models.Model):
    reg_number = models.CharField(max_length=10,primary_key=True)
    month_year = models.CharField(max_length=20)
    type = models.CharField(max_length=20)
    wheelbase = models.CharField(max_length=20)
    cubic = models.CharField(max_length=20)
    cylinder = models.CharField(max_length=20)
    ledan_unledan = models.CharField(max_length=50)
    maker = models.CharField(max_length=50)
    model = models.CharField(max_length=50)
    color = models.CharField(max_length=50)
    body_type = models.CharField(max_length=50)
    seating = models.CharField(max_length=6)
    rto = models.CharField(max_length=50)
    finance = models.CharField(max_length=50,blank=True,null=True)

    now = models.DateField(auto_now_add=True,auto_created=True)
    image = models.ImageField(upload_to='SmartRc/',blank=True, null=True)
    class Meta:
        ordering = ('-now',)
    def save(self, *args, **kwargs):
        img = Image.open('media/back.png' )
        # fnt = ImageFont.truetype('/Library/Fonts/Arial.ttf', 15)
        d = ImageDraw.Draw(img)
        bold = ImageFont.truetype("media/arial-BoldMT.ttf",size=15,)
        font = ImageFont.truetype("media/Arial-BoldMT.ttf",size=16,)
        d.text((226,48), self.type, fill=(14, 15, 15),font=bold, stroke_fill="black")
        d.text((40,93), self.reg_number, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((40,134), self.month_year, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((40,174), self.wheelbase, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((40,213), self.cubic, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((40,253), self.cylinder, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((40,315), self.ledan_unledan, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((196,93), self.maker, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((196,134), self.model, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((196,174), self.color, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((196,213), self.body_type, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((196,253), self.seating, fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((196,298), "LIFE TIME", fill=(14, 15, 15),font=font, stroke_fill="black")
        d.text((451,399), self.rto, fill=(14, 15, 15),font=font, stroke_fill="black")
        if self.finance:
            textwrapped = textwrap.wrap(self.finance, width=20)
            d.text((455,259), '\n'.join(textwrapped), fill=(14, 15, 15),font=font, stroke_fill="black")
        img.save(f'{self.reg_number} back.png')
        destination_file = open(f'{self.reg_number} back.png', 'rb')
        self.image.save(f'{self.reg_number} back.png', File(destination_file), save=False)

        super(SmartRCBack, self).save(*args, **kwargs)


    def __str__(self):
        return f'{self.rto} {self.reg_number}'

我在这一行遇到错误，所以我尝试了 3 种方法来解决问题 这 3 种方法

font = ImageFont.truetype("arial-BoldMT.ttf", size =16) 

font = ImageFont.truetype("fullpath of the file/arial-BoldMT.ttf", size =16) 

font = ImageFont.truetype("settings.MEDIA_ROOT/arial-BoldMT.ttf", size =16) 

STATIC_URL = "/static/"
MEDIA_URL = "/media/"
MEDIA_ROOT = "/home/Amar2022/rto/media"
STATIC_ROOT = "/home/Amar2022/rto/static"

urlpatterns = [
    path('admin/', admin.site.urls),
    path('rc/',include('rc.urls'))
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

pythonanywhere web 配置路径图片

但它的工作ImageFont.load_default（）我想要3个不同的fonts arialbold，arialbt，arialblack，arial所以它在本地机器上工作如果有任何package可用于安装fonts
