Rails 3 - wkhtmltopdf command failed: about pdfkit HOT 27 CLOSED

after some more reading, the problem might be related to the command actually not being executed, but I can't see the problem right now

(maybe ree related?)

edit: working without ree. so?

from pdfkit.

You probably need to make the config.wkhtmltopdf be an absolute path to the executable.

from pdfkit.

I tried with absolute path, restarted the server, but got the same error.

from pdfkit.

This solution worked so that PDFKit doesn't crash (http://stackoverflow.com/questions/3468234/rails-3-wkhtmltopdf-command-failed-when-using-pdfkit-to-create-pdf-documents):
PDFKit.configure do |config|
config.default_options[:ignore_load_errors] = true
end

But now, any PDF document I try to create comes out blank. What could be causing this?

from pdfkit.

Could you post the HTML that your using to generate the PDF? The wkhtmltopdf binary may not be able to download some resources mentioned in the HTML. This can be especially true in development where you only have one server running.

What happens is a request for a PDF comes in and wkhtmltopdf needs to download a file to generate the pdf, issues a request, but that request sits behind the original request which is trying to create the pdf.

Hi,
I've got the same issue here. Adding a trailing space in the path to the executable seems to help, so I would recommend to check for a missing space somewhere in pdfkit

config.wkhtmltopdf = '/usr/bin/wkhtmltopdf '

from pdfkit.

@jdpace, I'm having that problem; the binary is not able to download some resources and so the process just seems to hang. Is there any way to work around that in development?

Thanks,
Jake

hi,
i am having problem as follows,

"command failed: /usr/local/bin/wkhtmltopdf--margin-right0.75in--page-sizeA4--margin-top0.75in--margin-bottom0.75in--disable-smart-shrinking--encodingUTF-8--margin-left0.75in--quiet--"

how can i overcome this issue? Please suggest solution ASAP..

Thanks

Hi, sorry for the late reply. I looked at the HTML in the page I'm trying to convert to PDF, and there's only the standard Rails Javascript files referenced, plus a CSS file. I also tried Saten's first recommendation (trailing space), with no luck.

Anything else I can try?

from pdfkit.

We had a weird instance where using 14px fonts caused wkhtmltopdf to crash on a linux box. You might be having a similar issue. Just try reducing the complexity of what you're rendering (maybe render it without the css) and see if that works. If it works without css, then put your css back in and start removing things in the css until it works. That's what we did -- and, strangely, changing the font size to 13px made all the difference. Go figure.

from pdfkit.

@nishandan - What happens when you run wkhtmltopdf directly? Note that command that was output was formatted badly. Try /usr/local/bin/wkhtmltopdf - test.pdf then type in some HTML and then hit ctrl+d.

from pdfkit.

when i execute the following command via terminal its working.

wkhtmltopdf www.google.com google.pdf

but when i access through the application using PDFKit gem it gives.

when i went through the source its raising from pdfkit.rb file in the following line
raise "command failed: #{command}" if result.to_s.strip.empty?. that means the result is empty(result = pdf.gets(nil)).

following error is displaying on web page
"command failed: /usr/local/bin/wkhtmltopdf--margin-right0.75in--page-sizeA4--margin-top0.75in--margin-bottom0.75in--disable-smart-shrinking--encodingUTF-8--margin-left0.75in--quiet--"

from pdfkit.

Is wkhtmltopdf installed at that location? What happens when you run /usr/local/bin/wkhtmltopdf www.google.com google.pdf

from pdfkit.

i did installation manually. that means i downloaded wkhtmltopdf and moved it to that location.

when i execute it generates pdf file.
/usr/local/bin/wkhtmltopdf www.google.com google.pdf

through the application, it worked properly on ubuntu 10.04 version. but not working on 9.10. is there any dependency libraries?

from pdfkit.

@nishandan: which ruby are you using?

from pdfkit.

I have the same problem in Rails 2 but I get a little more info

It says the error is coming from Ghostscript

from pdfkit.

X11 may not be installed on that box. Can you try installing the dependencies listed on this page? Let me know if that works. I'll try to update the Readme to be more helpful in this area.

from pdfkit.

i am using ruby version 1.8.7

i wanted to install following libraries,

fontconfig, build-essential, xorg, openssl, libssl-dev

some libraries will be installed on some ubuntu versions. unless we have to install those.

now it is working fine on ubuntu 10.04,9.10 and 8.04.

thanks for your comments.

hi, had some of the problems on rails 2.3.8 and 0.10.beta5 of wkhtmltopdf (which is installed automatically). i tried the options on console and found that the 0.10beta has changed quite a bit. so it accepts other options, and seems to depend on specific orders for toc and cover.
i've created a small fix for that in pdfkit, but on some cases i still get the error, that the command has failed, while the same commandstring on console works.

from pdfkit.

I am having the same problem in production and development with unicorn:

RuntimeError (command failed: /usr/local/bin/wkhtmltopdf --page-size Letter --margin-right 0.75in --margin-top 0.75in --ignore-load-errors --margin-bottom 0.75in --disable-smart-shrinking --encoding UTF-8 --margin-left 0.75in --quiet - -):

I am using haml for the templating language. Having no images and no stylesheets included seems to work fine.

WebBrick on the other hands works just fine with both images and stylesheets.

None of the above mentioned workarounds did help.
Do you need any additional log files for this, jdpace?

from pdfkit.

I have solved the unicorn issue by putting more than one worker in my development environment. In production, this is not an issue due to multiple workers running.

It seems to render my PDF's just fine now ;-)
Thanks jdpace for the great gem!

from pdfkit.

I had a similar problem, the pdfkit --install-wkhtmltopdf command was installing the i386 version, i need the 64bit version which is the amd64 one.

I have had the same problem. I tracked it down to having a url (http://whatever) in text form on the page. It will work fine if the url is part of an href in an [a] tag. But not if it is just displayed as text. Weird.
In order to find the problem, I commented out each line one at a time and tried to generate the pdf. It would always give me this error, until I removed the line that had the url. This only happens when using PDFKit. Not when using the command line form of wkhtmltopdf.

Hello guys I need some help, i was using the pdfkit version 5.0.3 and wkhtmltopdf 0.9.0, now other project in teh same server, needed to update wkhtmltopdf to version 11, and now my code is not working anymore, I'm receveing the following message:

RuntimeError (command failed: "/usr/bin/wkhtmltopdf" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-right" "0.75in" "--margin-bottom" "0.75in" "--margin-left" "0.75in" "--encoding" "UTF-8" "--quiet" "-" "-"):

Thanks Andreza

getting the same error only in production
RuntimeError (command failed: /usr/local/bin/wkhtmltopdf --page-size Letter --margin-top 0.75in --margin-right 0.75in --margin-bottom 0.75in --margin-left 0.75in --encoding UTF-8 --quiet - -):

running from the command line works fine.

from pdfkit.

@ginter how does running that from the command line work? Is the output correct?

from pdfkit.

I am getting the same error as @ginter in my staging/production env. In my case, I have tracked the issue to these meta config elements:

<meta name="pdfkit-margin-top" content="0mm"/>
<meta name="pdfkit-margin-bottom" content="0mm"/>
<meta name="pdfkit-margin-right" content="0mm"/>
<meta name="pdfkit-margin-left" content="0mm"/>

If I remove them everything is fine. pdfkit 0.5.4 and wkhtmltopdf 0.10.0.rc2
