Question

我正试图在我的rails 2.3环境中的windows中使用pdfkit。然而，pdfkit给出一些错误导致rails加载服务错误的中间件。我该怎么办？有没有PDFkit的替代方案易于使用？

我正在关注PDFKit上的Rails截屏视频。我安装了pdfkit gem，wkhtmltopdf，然后将environment.rb文件中的中间件加载为要求'pdfkit' config.middleware.use“PDFKit :: Middleware” 然后，当我去任何页面并添加.pdf扩展名时，我得到500服务器错误

如果您在Windows上使用pdfkit，则需要安装wkhtmltopdf。之后你需要在enviroment.rb上配置wkhtmltopdf，如下所示：D。

PDFKit.configure do |config|
   config.wkhtmltopdf = 'C:\opt\wkhtmltopdf\wkhtmltopdf.exe'
   config.default_options = {
     :page_size => 'Legal',
     :print_media_type => true
   }
   config.root_url = "http://localhost" # Use only if your external hostname is unavailable on the server.
end

我希望这会有所帮助。

rails中的PDFKit会导致服务500错误
