pdfkit command failed: “/usr/bin/wkhtmltopdf” “--page-size” “Letter” “… ”--quiet“ ”-“ ”-"

Error:

  Create PDF Error :
 
  RuntimeError (command failed: "/home/ubuntu/.rvm/gems/ruby-1.9.3-p392@xxx/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" "-" "-")

Solution:


 (1)  first, installing dependencies
 $sudo aptitude install openssl build-essential xorg libssl-dev

(2) for 64bits OS Run one by one following commands.

$sudo wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2
$sudo tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
$sudo mv wkhtmltopdf-amd64 /usr/local/bin/wkhtmltopdf
$sudo chmod +x /usr/local/bin/wkhtmltopdf

Finally Go to your rails app/config/initializer Folder and create new file pdfkit.rb and paste following code in it.

PDFKit.configure do |config|
   config.wkhtmltopdf = '/usr/local/bin/wkhtmltopdf' if Rails.env.production?
end
