Elastic Beanstalk 上的 Django Weasyprint - 无法加载 GDK-Pixbuf [英] Django Weasyprint on Elastic Beanstalk - Could not load GDK-Pixbuf

问题描述

我已经在 Elastic Beanstalk 上安装了 weasyprint.到目前为止，html 模板的打印工作正常，但我无法打印 svg 图像.

I've installed weasyprint on Elastic Beanstalk. The printing of html templates is working so far but im not able to print svg images.

Weasyprint 抛出以下错误:

Weasyprint throws the following error:

Failed to load image at "https://myurl/media/X247QAQ2IO.svg" (Could not load GDK-Pixbuf. PNG and SVG are the only image formats available.)

我是否需要 gdk-pixbuf 来打印 SVG?如果是这样，我如何在 Amazon Linux 上安装它?

Do I need gdk-pixbuf to print SVGs? And if so how can I install it on Amazon Linux?

Yum does not have gdk-pixbuf2 available for installation

推荐答案

通过手动构建 gdk-pixbuf2，我找到了一个对我有用的解决方案，下面的脚本来自 https://gist.github.com/whyvez/1e0212a35da97aa8f1b1 他们需要安装 image magic 的地方
