由于“wkhtmltopdf"，PDFKIT 显然无法正常工作； [英] PDFKIT apparently not working because of "wkhtmltopdf"

问题描述

我无法从 html 页面生成 PDF.

I'm having trouble generating a PDF out of a html page.

我正在使用 PDFkit.在安装它的过程中，我注意到我需要 wkhtmltopdf.所以我也安装了.我做了 PDFkit 文档所说的所有事情.. 现在我在尝试加载 PDF 时遇到了这个错误.

I'm using PDFkit. In the process of installing it, I noticed I needed wkhtmltopdf. So I installed it too. I did everything PDFkit's documentation said to do.. and now I'm getting this error when I try to load the PDF.

这里是错误:

command failed: "/usr/local/bin/wkhtmltopdf" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-"

知道这可能是什么吗?

谢谢

推荐答案

我的 rails 应用程序中有以下配置.我在 irb 中对其进行了测试，效果很好.

I have the following configuration in my rails application. I tested it in irb and it worked well.

PDFKit.configure do |config|
  config.wkhtmltopdf = `which wkhtmltopdf`.to_s.strip
  config.default_options = {
    :encoding=>"UTF-8",
    :page_size=>"A4",
    :margin_top=>"0.25in",
    :margin_right=>"1in",
    :margin_bottom=>"0.25in",
    :margin_left=>"1in",
    :disable_smart_shrinking=>false
    }
end

您需要设置 wkhtmlpdf 可执行文件的路径.

You need to set the path to wkhtmlpdf executable file.
