ruby-on-rails-3 - Ruby on Rails : PdfKit Runtime Error

Question

pdfkit gem 已成功安装在我的机器上。然后我运行 gem install wkhtmltopdf-binary 并输出为

Successfully installed wkhtmltopdf-binary-0.9.9.1
1 gem installed
Installing ri documentation for wkhtmltopdf-binary-0.9.9.1...

好吧，然后尝试访问我的页面的 pdf 版本。但它也向我显示了一个错误运行时错误ControllerName#show

command failed: "/home/yasir/.rvm/gems/ruby-1.9.3-p194/bin/wkhtmltopdf" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-right" "0.75in" "--margin-bottom" "0.75in" "--margin-left" "0.75in" "--encoding" "UTF-8" "--quiet" "-" "-

Answer 1

在 pdfkit 配置文件 (config/initializers/pdfkit.rb) 中添加 wkhtmltopdf 安装路径，如下

PDFKit.configure do |config|
  # Download compatible version of wkhtmltopdf from 'http://wkhtmltopdf.org/downloads.html'
  # Install it in your system.
  # Then run 'which wkhtmltopdf' in your terminal to identify the path and update it below
  config.wkhtmltopdf = '/usr/local/bin/wkhtmltopdf'
end
