问题描述
我正在用 Flask 构建一个网络应用程序，我正在尝试将 html 导出为 pdf 文件。
config = pdfkit.configuration(wkhtmltopdf=my_path_to_wkhtmltopdf_exe)
options = {
"disable-local-file-access": "","enable-local-file-access": None
}
html = render_template(<my_html_flie>)
pdf = pdfkit.from_string(html,False,configuration=config,options=options)
response = make_response(pdf)
我遇到的问题是代码在本地开发中运行得非常好。我已经在 docker 镜像上安装了 wkhtmltopdf、pdfkit 和 xvfb。所以我怀疑这与任何依赖问题有关。当我将它部署到 docker 容器时，它不再起作用，并且会在下面抛出一些错误
raise IOError("wkhtmltopdf exited with non-zero code {0}.error:\n{1}".format(exit_code,stderr))
OSError：wkhtmltopdf 以非零代码 1 退出。错误：

突出显示，我怀疑错误来自这一行，有人可以就可能出现的问题给我建议吗？
