RuntimeError (Error: Failed to execute: "/usr/bin/wkhtmltopdf"

I am using wkhtmltopdf(0.10.0 rc2) and wicked_pdf(0.9.9) for generating pdf report.
While running i got the following error.

RuntimeError (Error: Failed to execute:
["/usr/bin/wkhtmltopdf", "-q", "--page-size", "A4", "--margin-top", "5", "--margin-bottom", "10", "--margin-left", "5", "--margin-right", "5", "file:////tmp/[\"wicked_pdf\", \".html\"]21873-0", "/tmp/[\"wicked_pdf_generated_file\", \".pdf\"]21873-0"]
Error: PDF could not be generated!
 Command Error: Error: Failed loading page file:////tmp/["wicked_pdf", ".html"]21873-0 (sometimes it will work just to ignore this error with --load-error-handling ignore)
)

my controller are:

render :pdf => "#{@note_name}",:layout => '/layouts/pdf_template.html.erb', :template=>'pdf/financial/maintenance_exp/maintenance_exp_pdf.html.erb'

Any help would be appreciated.

FYI:when I do
:show_as_html=>true
its not throwing any error.its rendering the html in browser.

Could you try pointing your Gemfile at the master branch and let me know if that helps?

The currently released gem versions are designed to work with wkhtmltopdf 0.9.9 and earlier, and we are working the kinks out for later versions at the moment.

gem 'wicked_pdf', github: 'mileszs/wicked_pdf'

Answer 2 · 2014-11-21T09:36:43.000Z

Yes I tried the same.its throwing the same error..

Answer 3 · 2014-11-21T14:48:22.000Z

The tempfiles aren't getting transformed into path strings correctly:

file:////tmp/["wicked_pdf", ".html"]

What version of Ruby are you using?

Answer 4 · 2014-11-24T13:09:11.000Z

Ruby 1.9.3

Answer 5 · 2014-11-24T18:17:26.000Z

I'm having trouble reproducing the issue. Do you have any global settings (like :temp_path) set?

Can you paste the error you get against master, too?

I'm having the same problem with Rails 4.1.0 and Ruby 2.1.5
I have used 3 hours trying to find the problem but no success.

gem 'wicked_pdf', github: 'mileszs/wicked_pdf'
#gem 'wicked_pdf'
gem 'wkhtmltopdf-binary'

The last line complains about a different gem, if I remove that gem it will complain about a different one. So that must be a consequence of the real problem above.

The funny thing is that I have another project using wicked just the same and it works all fine. But that is Rails 4.0.0 and Ruby 2.1.5

Both projects use their own gemset and each gem set contains its binary.

My config is like this:

if Rails.env.production?
  WickedPdf.config = {
     :exe_path => Rails.root.join('bin', 'wkhtmltopdf-amd64').to_s
  }
else
   WickedPdf.config = {
      :exe_path => '/Users/josegranado/.rvm/gems/ruby-2.1.5@rails4.1.0/bin/wkhtmltopdf'
   }
end

It is interesting that if entering to the console, rails c and executing:
WickedPdf.new.pdf_from_string("test")

Seems to generate a pfd, but the same on a controller fails with the error above.

Any ideas?

UPDATE
The problem seems to be caused by Spring. Removing the sping gem got wicked_pdf working again.
I guess there's a way to have both but I didn't want to spend more time on this one.

Answer 7 · 2015-02-01T14:56:57.000Z

@josegrad Weird. I wonder what spring has to do with this?

Thanks for sharing that. I have a feeling it will help others.

Maybe it has something to do with bundle exec'ing the wkhtmltopdf command, I'll look into that.

Answer 8 · 2015-04-22T07:28:26.000Z

Brilliant! Same problem here. wicked_pdf kept complaining about some gem not being checked out on master. Removing spring from my Gemfile got wicked_pdf back to live. I was using wicked_pdf 0.11.0 with spring 1.3.4

Answer 9 · 2015-05-18T11:36:05.000Z

Updating to spring 1.3.6 seems to fix this issue for me.

Answer 10 · 2015-05-20T13:52:13.000Z

I had to disable spring too to make it work again :-(

Answer 11 · 2015-08-19T20:42:27.000Z

updating to 1.3.6 did not work had to take spring out entirely, it worked initially on my computer, but when another dev on the project pulled the update down it broke :-/

Answer 12 · 2015-09-10T17:44:03.000Z

getting the same issue even after removing/updating spring gem

Answer 13 · 2015-09-10T17:45:21.000Z

same here, getting the same issue even after removing spring

Answer 14 · 2015-11-29T19:42:58.000Z

updating spring and running bundle exec spring binstub --all fixed my issue.

Answer 15 · 2015-12-23T10:12:07.000Z

I got the same error. All i had to do was kill the spring process and restart my server. The error cleared immediately.

Answer 16 · 2016-01-19T17:07:49.000Z

I am getting the same error on Ruby 2.3.0 and rails 5.0.0.beta1:

This was working on Ruby 2.1.5 and rails 4.2.0.

I have tried what suggestions here. Any ideas?

check file permissions of wkhtmltopdf file

Answer 19 · 2016-02-23T16:43:17.000Z

stopping spring and restart rails server fixed the problem for me

Answer 20 · 2016-03-24T22:51:52.000Z

Possible relation? I'm not using spring on Heroku, only locally where the PDF gen works well, however the errors look similar.

#512

Answer 21 · 2016-03-25T18:55:48.000Z

@micahlisonbee I don't think they are related. They only look similar because of the specific error logging output in WickedPDF.

Answer 22 · 2016-03-25T19:22:53.000Z

@mileszs agreed.

Answer 23 · 2016-07-28T18:40:30.000Z

Thanks @arashm.. This solved the error for me as well: bundle exec spring binstub --all

Answer 24 · 2016-08-09T16:35:33.000Z

Thanks @frahugo and @arashm bundle exec spring binstub --all worked for me as well. Rake and rails where both and the error went away.

Can you please guide the Solution?

Answer 27 · 2020-01-02T14:49:05.000Z

@DevRor1 The message you posted contains the problem, which points to a solution.

It can't find a version of wkhtmltopdf installed (with the binary gem) that runs on the version of linux this error is coming from (looks like Amazon).

There's a PR to that project that suggests that the CentOS 6 binary works on that platform

Do you think you could verify that fix works for you by pointing your Gemfile at his version like this:

gem 'wkhtmltopdf-binary',
  git: 'https://github.com/entretechno/wkhtmltopdf_binary_gem',
  branch: 'amazon-linux'

And report back if that works for you or not?

Hi @unixmonkey, I have been following this thread as am getting the same error.
As per your last comment, I am now using wkhtmltopdf-binary from https://github.com/entretechno/wkhtmltopdf_binary_gem and after deploying, when I tested the pdf output, I am getting:

RuntimeError: Failed to execute:
["/opt/rubies/ruby-2.6.5/bin/wkhtmltopdf", "--orientation", "Landscape", "--margin-top", "25", "--margin-bottom", "10", "--header-spacing", "3", "--header-html", "file:////tmp/wicked_header_pdf20200121-17753-1dq4e4f.html", "--footer-html", "file:////tmp/wicked_footer_pdf20200121-17753-1g9svx6.html", "file:////tmp/wicked_pdf20200121-17753-19kc290.html", "/tmp/wicked_pdf_generated_file20200121-17753-7w7n6j.pdf"]

from /opt/rubies/ruby-2.6.5/bin/wkhtmltopdf:23:in `load'
from /opt/rubies/ruby-2.6.5/bin/wkhtmltopdf:23:in `<main>'

The exe_path is set as:

WickedPdf.config = {
  exe_path: '/opt/rubies/ruby-2.6.5/bin/wkhtmltopdf'
}

Is this something you can help with? In my earlier Rails-5.2.3 version (running on Ruby-2.3.8), with wicked_pdf 1.4.0 and wkhtmltopdf-binary 0.12.4 with same exe_path this was not the issue

Current Platform:
Ruby 2.6.5
Rails 6.0.2.1
Wicked PDF : gem 'wicked_pdf', github: 'mileszs/wicked_pdf', branch: 'master'
Wkhtmltopdf-binary: gem 'wkhtmltopdf-binary', git: 'https://github.com/entretechno/wkhtmltopdf_binary_gem', branch: 'amazon-linux'

kindly suggest

P.S. Since I am using a different source/version of wkhtmltopdf-binary, I am going to test this another time by changing the exe_path

WickedPdf.config = {
  exe_path: '/opt/rubies/ruby-2.6.5/bin/wkhtmltopdf-linux-amd64'
}

I will post my findings here shortly
[UPDATE]: Nothing changed after changing the config to new location

I am now going to remove config/initializers/wicked_pdf.rb and test this

OK, now I have same wicked_pdf version, same wkhtmltopdf-binary version (i.e. amazon-linux, no wicked_pdf.rb inside config/initializers and error tail is below:

RuntimeError: Failed to execute: ["/opt/rubies/ruby-2.6.5/lib/ruby/gems/2.6.0/bin/wkhtmltopdf", "--orientation", "Landscape", "--margin-top", "25", "--margin-bottom", "10", "--header-spacing", "3", "--header-html", "file:////tmp/wicked_header_pdf20200121-24488-134jtns.html", "--footer-html", "file:////tmp/wicked_footer_pdf20200121-24488-z76ze3.html", "file:////tmp/wicked_pdf20200121-24488-2izkpv.html", "/tmp/wicked_pdf_generated_file20200121-24488-baqg2f.pdf"]

[UPDATE]: Surprisingly, when I executed this command: WickedPdf.new.pdf_from_string('<h1>Hello There!</h1>') from my staging's web console, it worked!
And after that when I tried to see it in action from Web, the PDF generation is now happening correctly

Here's what I did (to summarise)
Using gem 'wicked_pdf', github: 'mileszs/wicked_pdf', branch: 'master'
Using gem 'wkhtmltopdf-binary', git: 'https://github.com/entretechno/wkhtmltopdf_binary_gem', branch: 'amazon-linux'
Using ruby '2.6.5'
Using gem 'rails', '~> 6.0', '>= 6.0.2.1'
Removed config/initializers/wicked_pdf.rb

I do have a question though! How amazon-linux branch of wkhtmltopdf-binary is different from it's base branch? And is it okay to refer this branch instead of master/base or using it directly from rubygems.org

Answer 29 · 2020-01-21T14:56:49.000Z

@puneetpandey That branch has a binary specific to Amazon Linux, whereas the base branch and the released gem don't (yet anyway).

The prior version of the gem must have just worked with Amazon Linux (0.12.4 was built differently from 0.12.5).

It's fine to refer to that branch for now, but if that branch gets merged, it could get deleted. However the code would be in the main wkhtmltopdf-binary gem. It is a little safer to fork to your own repository and point to that, in case that happens.

Alternately, you could simply pull the binary you need into your app at bin/wkhtmltopdf and point exe_path at that, but if you develop on a different platform, you'll likely need more than one version.
