Rails 3 + PDFKit问题:权限被拒绝(Errno :: EACCES)

Question

我想在Windows上的 Rails 3应用程序中使用PDFKit.

我装wkhtmltopdf了pdfkit宝石.

这是我用来创建PDF的代码:

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"

有任何想法吗 ？

如果指向文件夹而不是实际文件(.exe),则会出现该错误

我让PDFkit在这样的Windows上运行:

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