Setting wkhtmltopdf path in rails

Question

I'm having this error when I try to use wicked_pdf:

irb: No such file or directory - which wkhtmltopdf
NoMethodError: You have a nil object when you didn't expect it!
The error occurred while evaluating nil.chomp
        from C:/Ruby187/lib/ruby/gems/1.8/gems/wicked_pdf-0.7.2/lib/wicked_pdf.r
b:19:in `initialize'
        from (irb):2:in `new'
        from (irb):2
        from :0

I think the path to wkhtmltopdf should be configured. But how?

Answer 1

According to the sources, simply add it to your $PATH (the folder containing the binary).

Answer 2

Provide sth like

:wkhtmltopdf => '/usr/local/bin/wkhtmltopdf', # path to binary

with your render call and make sure, that a wkhtmltopdf binary resides at that path. (You can get wkhtmltopdf from google code in case you have not installed it yet)

Answer 3

Wkhtmltopdf project can't be found on Google Code any longer. It was moved to http://wkhtmltopdf.org/downloads.html

In my case, I just had to download the OSX binary and it was automatically added to my PATH variable.

Answer 4

Create an initializer: config/initializers/wicked_pdf.rb:

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

:exe_path should hold the path to the wkhtmltopdf binary. For my instance, I used the gem:

gem "wkhtmltopdf-binary"

Which stored the binary in my GEM_HOME, so I could reference a path that wasnt hard coded.
