Rails: Error running wkhtmltopdf — (error while loading shared libraries)

Question

When my app runs (or when I run from commandline) the wkhtmltopdf command I get the following error: (showing it from command line)

#> wkhtmltopdf 
wkhtmltopd         


        

Answer 1

Note that there is an executable version of wkhtmltopdf distributed in a UPX compressed format, ldd and file will both report that this file is statically linked even though the payload requires shared libraries.

To check try

strings | fgrep UPX

If you see any "UPX" id strings then install upx and use "upx -d" on a copy of the file (as upx works in place) and then run ldd on the uncompressed file.

Answer 2

Ran into this today on a RHEL7 machine running the static version of wkhtmltopdf. Solution was to install a few dependencies:

yum install libXrender libXext fontconfig 

Answer 3

I need also do after:

sudo apt-get install libfontconfig1

Answer 4

sudo apt-get install xvfb

to install the dependency package.

Update the node-modules wkhtmltopdf index.js

wkhtmltopdf.command = 'wkhtmltopdf'; to 'wkhtmltopdf.command = 'xvfb-run wkhtmltopdf';'

Answer 5

I was having the exact same problem! The solution, to me, was to install the 64bit version of wkhtmltoimage.

Answer 6

With Ubuntu 16 (from a fresh Docker install):

apt install -y libxrender1 libxext6
