windows - 权限被拒绝使用 wicked_pdf

Question

我在用

Windows 7  
Rails 3.2.11  
wkhtmltopdf 0.9.9

在 gem 文件中

gem 'wicked_pdf'

在我的初始化程序中

WickedPdf.config = { :exe_path => 'C:\wkhtmltopdf' }

exe位于

C:\wkhtmltopdf\wkhtmltopdf.exe

当我从 rails c 运行时

irb(main):001:0> WickedPdf.new.pdf_from_string('<h1>Hello There!</h1>')

我收到以下错误...

"*******\"C:\wkhtmltopdf\"
\"file:///C:/Users/bob/bob_rail s_demo/Course_Stats/wicked_pdf20130307-6328-7cuwz7.html\" \"C:/Users/bob/wful ts_rails_demo/Course_Stats/wicked_pdf_generated_file20130307-6328-n902yj.pdf\" * ******" RuntimeError: Failed to execute: "C:\wkhtmltopdf" "file:///C:/Users/bob/bob_rails_demo/Course_Stats/ wicked_pdf20130307-6328-7cuwz7.html" "C:/Users/bob/bob_rails_demo/Course_S tats/wicked_pdf_generated_file20130307-6328-n902yj.pdf" Error: Permission denied - "C:\wkhtmltopdf" "file:///C:/Users/bob/wful ts_rails_demo/Course_Stats/wicked_pdf20130307-6328-7cuwz7.html" "C:/Users/bob /bob_rails_demo/Course_Stats/wicked_pdf_generated_file20130307-6328-n902yj.pd f" from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/wicked_pdf-0.9 .4/lib/wicked_pdf.rb:50:in rescue in pdf_from_string'

如果我将此行更改为...

WickedPdf.config = { :exe_path => 'C:\wkhtmltopdf\wkhtmltopdf.exe' }

然后在 rails 命令行中运行它似乎可以工作，但在我的应用程序中 Rack 中间件只是挂起...

我遇到了同样的问题，除了最初我的 exe 位于 C:\Program Files (x86)\wkhtmltopdf\wkhtmltopdf.exe

所以我将其更改为 C:\wkhtmltopdf\wkhtmltopdf.exe(您已经拥有)，然后我将 :exe_path 设为::exe_path => 'C:\wkhtmltopdf\wkhtmltopdf.exe'

我相信您必须在 Windows 环境中添加 .exe 的原因是因为 Windows 需要显式指定文件路径。一旦我这样做了，它就像一个魅力。

让我知道进展如何(或进展如何)!
