Rails: wkhtmltopdf RuntimeError (Location of wkhtmltopdf unknown)

I am using Ubuntu 11.04 to develop开发者_如何学运维 an app in Ruby on Rails. In the app I need to generate pdf documents. So I am using the wicked_pdf and wkhtmltopdf-binary gems.

In the development environment in my system everything is working fine. But once I deployed the app in production on CentOS 5.6 using Phusion Passenger, when I try to generate pdfs on the fly its giving me the following error:

RuntimeError (Location of wkhtmltopdf unknown)

I am using Ruby1.9.2.p136 Rails 3.1.1

Any help will be much appreciated....Thanks.


An alternative is to install the binary via the Gemfile.

Just add the following line to your production group:

gem 'wkhtmltopdf-binary'

That should add binary support for linux-i386, amd64, and darwin.

And then run

bundle install --without development test

to install the gem in a production environment. After which, you just restart your server.

That's all.

I hope this helps


do you use static wkhtmltopdf binary? i downloaded it here and extraced it to /path/to/rails_app/bin

and add it to rails like this:

#config/initializers/wicked_pdf.rb
WickedPdf.config = {
  :exe_path => Rails.root.join('bin', 'wkhtmltopdf-i386').to_s,
}


for mac os - x you should install wkhtmltopdf by homebrew

$ brew tap homebrew/boneyard # the wkhtmltopdf formula is now inactive but still available in the boneyard repository 
$ brew install wkhtmltopdf


Solution for OS X Yosemite

To get it working on Mac OS X 10.10 (Yosemite), install the wkhtmltopdf-binary gem and then put it in your config/initializers/wicked_pdf.rb:

module WickedPdfHelper
  if Rails.env.development?
    if RbConfig::CONFIG['host_os'] =~ /linux/
      executable = RbConfig::CONFIG['host_cpu'] == 'x86_64' ? 'wkhtmltopdf_linux_x64' : 'wkhtmltopdf_linux_386'
    elsif RbConfig::CONFIG['host_os'] =~ /darwin/
      executable = 'wkhtmltopdf_darwin_386'
    else
      raise 'Invalid platform. Must be running linux or intel-based Mac OS.'
    end

    WickedPdf.config = { exe_path: "#{Gem.bin_path('wkhtmltopdf-binary').match(/(.+)\/.+/).captures.first}/#{executable}" }
  end
end

Ps.: This solution will work on Linux too.


MAC OSX:

brew install wkhtmltopdf

this will let you to install

brew install Caskroom/cask/wkhtmltopdf

then in config/initializers/wicked_pdf.rb

WickedPdf.config = {
  exe_path: '/usr/local/bin/wkhtmltopdf'
}


Just had a similar problem.

As stated in readme, I created an initializer with:

WickedPdf.config = {
  exe_path: '/usr/local/bin/wkhtmltopdf'
}
