我已在 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。
Weasyprint 抛出以下错误:
Failed to load image at "https://myurl/media/X247QAQ2IO.svg" (Could not load GDK-Pixbuf. PNG and SVG are the only image formats available.)
我需要 gdk-pixbuf 来打印 SVG 吗?如果是这样,我如何在 Amazon Linux 上安装它?
Yum does not have gdk-pixbuf2 available for installation
最佳答案
我通过手动构建 gdk-pixbuf2 找到了一个适合我的解决方案,下面的脚本源自 https://gist.github.com/whyvez/1e0212a35da97aa8f1b1他们需要在哪里安装图像魔法
