hinzufügen wkhtmltopdf Installationspfad in Ihrer PDFKit Konfigurationsdatei (config/initializers/pdfkit.rb), wie unten

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
