Hi,
I want to run wkhtmltopdf as a child_process on an Ubuntu system. I want to
use stdin and stdout of the child_process. I use the following script for
running the cp:
var cp = require('child_process');
var streams = cp.spawn('wkhtmltopdf', ['-q', '-', '-'])
streams.stdout.on('data', function(data) { console.log(data.toString()) });
streams.stderr.on('data', function(data) { console.log(data.toString()) });
streams.on('exit', function(code) {
console.log('exit', code);
});
streams.stdin.end('Hello World', 'utf8');
wkhtmltopdf can be downloaded
from http://code.google.com/p/wkhtmltopdf/downloads/list. I used the static
build.
This script is working on Mac OS X 10.8 with node 0.6.21 and 0.8.5 without
problems. On Ubuntu the script is working with node 0.6.x but not with
0.8.x. I tested this with Ubuntu 10.04 32bit and 11.10 64bit. wkhtmltopdf
says that the destination is not writable. Are there any important changes
made in 0.8.x which I need to know to get the script running?
