一运行cairo_pdf命令就出错:cairo_pdf(bg="grey98", pdf_file, width=13,height=10.5)
错误提示:Error in cairo_pdf(bg = "grey98", pdf_file, width = 13, height = 10.5) :
unable to start device 'cairo_pdf'
In addition: Warning message:
In cairo_pdf(bg = "grey98", pdf_file, width = 13, height = 10.5) :
cairo error 'error while writing to output stream'
谁有好的解决方法,麻烦赐教
