Wicked PDF silently fails on OS X


With the same code and gem versions, it works just fine in Ubuntu (14.04, 64bit). Currently I am using:

  • wkhtmltopdf-binary gem v0.9.9.1
  • wicked_pdf gem v0.10.2
  • Rails 4.1.1
  • Ruby 2.1.3
  • OS X 10.10, 64-bit

When I tried to generate PDF from Rails, i get the error message: wkhtmltopdf_darwin_386 quit unexpectedly. Here's the full error message:

The reason why I said silently in the title, is because when I inspected the server log it's running just fine. Here's an excerpt:

"***************\"/Users/david/.rbenv/versions/2.1.3/bin/wkhtmltopdf\" -q  --footer-html \"file:////var/folders/4w/fybp8mln1pn91cqrxq6z2kcc0000gp/T/wicked_footer_pdf20141118-1102-1uce4hg.html\"     --margin-bottom 13    \"file:////var/folders/4w/fybp8mln1pn91cqrxq6z2kcc0000gp/T/wicked_pdf20141118-1102-1jrv3s8.html\" \"/var/folders/4w/fybp8mln1pn91cqrxq6z2kcc0000gp/T/wicked_pdf_generated_file20141118-1102-qu51nc.pdf\" ***************"
  Rendered text template (1.1ms)
Sent data test.pdf (8.4ms)
Completed 200 OK in 6516ms (Views: 7.5ms | ActiveRecord: 6.8ms)

Running which wkhtmltopdf gives me /Users/david/.rbenv/shims/wkhtmltopdf.. When I ran tested wkhtmltopdf separately (as in wkhtmltopdf test1.html test1.pdf) it runs perfectly.

Is it possible that wkhtmltopdf_darwin_386 doesn't work well in 64-bit based architecture? (Even though my Ubuntu is also 64-bit based.)

Any help is appreciated.

Have you done this? :

create/edit file:


If your wkhtmltopdf executable is not on your webserver's path, you can configure it in an initializer:

WickedPdf.config = {
  :exe_path => '/Users/USER/*/wkhtmltopdf_darwin_386'
