我已经尝试过here的答案，但是没有解决任何问题。
我已将文件提取到建议here的fonts文件夹中，但没有任何作用。
如果这可能是问题之一，我正在使用虚拟环境。
我尝试添加名称为Times-Roman的字体，但效果不佳。
[请注意，我使用的是Windows操作系统，使用Pyinstaller构建应用程序时会发生此错误。
这是我的目录的样子：

在this user guide中，您会找到所需的所有内容（尤其是第48-52页）。
基本上，您需要以Adobe .afm（'Adobe Font Metrics'）和.pfb（'Printer Font Binary'）格式包括字体描述文件。
因此这是DarkGardenMK的示例，从那里获取：
import os
import reportlab
folder = os.path.dirname(reportlab.__file__) + os.sep + 'fonts'
afmFile = os.path.join(folder, 'DarkGardenMK.afm')
pfbFile = os.path.join(folder, 'DarkGardenMK.pfb')
from reportlab.pdfbase import pdfmetrics
justFace = pdfmetrics.EmbeddedType1Face(afmFile, pfbFile)
faceName = 'DarkGardenMK' # pulled from AFM file
pdfmetrics.registerTypeFace(justFace)
justFont = pdfmetrics.Font('DarkGardenMK', faceName, 'WinAnsiEncoding')
pdfmetrics.registerFont(justFont)
canvas.setFont('DarkGardenMK', 32)
canvas.drawString(10, 150, 'This should be in')
canvas.drawString(10, 100, 'DarkGardenMK')
因此，请测试它是否可以工作-您可以直接使用该字体，如果它确实对Times-Roman字体（以及相应的.afm，.pfb文件）也是如此。如果失败，请参阅第51页，“ TrueType字体支持”的说明。
希望有帮助！
