我正在尝试在我的服务器上使用wicked_pdf,但是它会持续下去：
RuntimeError (Failed to execute: "/usr/bin/wkhtmltopdf" -q "file:////tmp/wicked_pdf20130709-23109-1adqx5g.html" "/tmp/wicked_pdf_generated_file20130709-23109-1ic5dbe.pdf" Error: PDF could not be generated! Command Error: wkhtmltopdf: cannot connect to X server ): app/controllers/contrats_controller.rb:15:in `block (2 levels) in show' app/controllers/contrats_controller.rb:11:in `show'
我试图按照这个答案：wkhtmltopdf: cannot connect to X server但仍然不行.
解决方法
这篇文章帮我解决了我的问题：

我正在复制这篇文章,帮助我安装它：
# first,installing dependencies sudo aptitude install openssl build-essential xorg libssl-dev # for 64bits OS wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2 tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2 mv wkhtmltopdf-amd64 /usr/local/bin/wkhtmltopdf chmod +x /usr/local/bin/wkhtmltopdf
他还创建一个初始化程序来告诉pdfKit它在哪里,所以这种方法是用于恶意的PDF和PDF工具包.
