Question

我正在使用python生成令牌作为安全措施。这是代码：

ERROR in app: Exception on /registration [POST], referer: http://my.com/registration

File "/usr/lib/python3/dist-packages/PIL/ImageFont.py", line 239, in truetype, referer: http://my.com/registration

return FreeTypeFont(font, size, index, encoding), referer: http://my.com/registration

File "/usr/lib/python3/dist-packages/PIL/ImageFont.py", line 128, in __init__, referer: http://my.com/registration

self.font = core.getfont(font, size, index, encoding), referer: http://my.com/registration

OSError: cannot open resource, referer: http://my.com/registration

错误似乎是加载字体的能力。虽然我从PIL导入ImageFont。

错误信息如下：

  d3.select('#date_select').on('change', function(){ 
    var nd = new Date(), now = new Date();
    switch (this.value) {
      case "today":
        nd = d3.time.day(now);
        break;
      case "week":
        nd = d3.time.monday(now);
        break;
      case "month":
        nd = d3.time.month(now);
        break;
      default:
        nd.setDate(nd.getDate() - +this.value);
    }
    dim.filterAll();
    dim.filterRange([nd, now]);
    //did not work graph.replaceFilter(dc.RangedFilter(nd, now));
    graph.redrawGroup();
  });

我的理解是ImageFont导致问题，因为它无法加载正确的字体。我不知道如何解决它。更令人费解的是它曾经工作过，直到我把它放在服务器上。

遇到相同的问题，很明显font无法找到PIL文件。

在font = ImageFont.truetype("arial.ttf", 15)中找不到arial.ttf。

解决方案是CD /usr/share/fonts/truetype，并找到可用的字体文件，然后用"arial.ttf"替换。（对于Windows用户，C:\WINDOWS\Fonts 中的字体文件）< / p>

OSError：尝试使用ImageFont.py时无法打开资源
