缺少字体使Tkinter应用程序混乱

Question

我为我的应用程序制作了一个简单的字体预览器。这在我的Macbook Pro上正常工作，但在我的个人Macbook Pro上却报错。我相信问题是缺少字体。这是打印到终端的错误：

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  45 (X_OpenFont)
  Value in failed request:  0x600173
  Serial number of failed request:  5292
  Current serial number in output stream:  5293

这是出现错误的代码

    def __init__(self, parent):
        tk.Toplevel.__init__(self, parent)
