ruby-on-rails - 生产中 wkhtmltopdf-binary gem 的问题

Question

我正在使用 gem 'wicked_pdf' 将 html 转换为 pdf。它在开发模式下运行良好。但在生产中它被 nginx 抛出错误。这是生产中的错误日志:

我猜测我有一个缺少库的问题:libXrender.so.1

我在生产环境中使用 ubuntu 16.04 ruby​​:2.4.1 和 rails 5.1.4我可以得到你的支持吗？

Answer 1

听起来您的生产服务器没有安装 xserver。

sudo apt-get install libxrender1

应该在 Ubuntu 上为您工作。
