Bad wkhtmltopdf's path for wicked_pdf and wkhtmltopdf

Question

I am using two Gems to convert HTML to PDF.

Using "https://github.com/mileszs/wicked_pdf"

gem 'wicked_pdf'
gem "wkhtmltopdf-binary"

/initializer/wicked_pdf.rb

WickedPdf.config = {
  exe_path =>  "xxxxxxxxxxxxxxxxxxx"
}

What path should I use for the exe_path ?

Answer 1

which wkhtmltopdf

This will give you path of your wkhtmltopdf. You should copy this path and paste in your config/intializers/wicked_pdf.rb And then restart your server.

Answer 2

Add this to config/initializers/wicked_pdf.rb ensuring your correct GEM_HOME is being referenced:

WickedPdf.config = {
  :exe_path => "#{ENV['GEM_HOME']}/bin/wkhtmltopdf"
}

This way you wont be hard coding any paths.

Answer 3

config/initializers/wicked_pdf.rb

path = `which wkhtmltopdf`.gsub(/\n/, "")

WickedPdf.config = { exe_path: path }
