python-3.x - Flask Pdfkit-无法添加自定义字体

Question

我正在尝试包含我的自定义字体，但出现以下错误，表明未找到该字体。但是，我可以确认我正确地指向字体目录。

OSError: wkhtmltopdf reported an error:

Error: Failed to load file:///C:/Users/xxxxx/AppData/Local/Temp/cmunrm.ttf, with network status code 203 and http status code 0 - Error opening C:/Users/xxxxx/AppData/Local/Temp/cmunrm.ttf: No such file or 

app.py 的代码片段

@app.route('/getDetails', methods=['POST'])
def x():
    if request.method == 'POST':
        path_wkhtmltopdf = 'static/wkhtmltopdf/bin/wkhtmltopdf.exe'
        config = pdfkit.configuration(wkhtmltopdf=path_wkhtmltopdf)
        rendered=render_template('resume.html',test='hi')
        cssPath=['static/css/resumeCss.css']
        pdf=pdfkit.from_string(rendered, False,configuration=config,css=cssPath)
        response=make_response(pdf)
        response.headers['Content-Type']='application/pdf'
        # response.headers['Content-Disposition']='attachment; filename=Print Me.pdf'
        response.headers['Content-Disposition']='inline'
        return response

简历CSS.css

@font-face {
  font-family: myFirstFont;
  src: url('../fonts/cmunrm.ttf');
}
h1{
  font-family: myFirstFont;
}

我还浏览了 wkhtmltopdf 的文档并查看了选项，但也找不到在那里加载字体的选项。
