Rails 3 + PDFKit 问题:权限被拒绝 (Errno::EACCES) [英] Rails 3 + PDFKit Problem: Permission denied (Errno::EACCES)

问题描述

我想在我的 Rails 3 应用程序在 Windows 中使用 PDFKit.

I would like to use PDFKit in my Rails 3 application on Windows.

我安装了 wkhtmltopdf 和 pdfkit gem.

I installed wkhtmltopdf and the pdfkit gem.

这是我用来创建 PDF 的代码:

Here is the code that I use to create the PDF:

class JobsController < ApplicationController
  def create_pdf_invoice
    kit = PDFKit.new("<h1>Hello</h1><p>This is PDF!!!</p>", :page_size => "A4")
    file = kit.to_file("my_first_pdf")   # Error issued here!!
    ...
  end
end

我收到以下错误:

Errno::EACCES in JobsController#create_pdf_invoice

Permission denied - "c:\Program Files\wkhtmltopdf" "--page-size" "A4" 
                    "--margin-top" "0.75in" "--margin-right" "0.75in" 
                    "--margin-bottom" "0.75in" "--margin-left" "0.75in" 
                    "--encoding" "UTF-8" "--quiet" "-" "my_first_pdf"

有什么想法吗?

推荐答案

如果您指向文件夹而不是实际的文件 (.exe)

You will get that error if you point to a folder and not the actual file (.exe)

我让 PDFkit 像这样在 Windows 上运行:

I got PDFkit to run on windows like this:

  PDFKit.configure do |config|
    config.wkhtmltopdf = 'C:\wkhtmltopdf\wkhtmltopdf.exe'
  end
