Phantom manager could not start all workers - express

Question

I trying to create a pdf using phamton-html-to-pdf and ejs for templating. The setup work greate in my local dev env, but not in production. The problem is that in my server prod the pdf is created but it is empty.
const ejs = require('ejs');
const fs = require('fs');
const conversion = require("phantom-html-to-pdf")({
phantomPath: require("phantomjs-prebuilt").path
});
function createPdf (data, template, directory) {
var options = {};
var html = ejs.renderFile(__dirname + `/template/${template}.ejs`, {data: data}, options, function(err, str){
if(err){
return err
}
return str
});
var filepath = null
conversion({ html: html, printDelay: 5000}, (err, pdf) => {
var output = fs.createWriteStream(`documents/${directory}/${data.Référence}.pdf`)
pdf.stream.pipe(output);
});
}
module.exports = createPdf;
{ Error: phantom manager could not start all workers..

Answer 1

You have to install 'libfontconfig' in your server.
macOS sierra update works only with phantomjs2.
linux may need to additionally install fontconfig package.
Centos - sudo yum install -y fontconfig
Debian/Ubuntu - sudo apt-get install -y libfontconfig

Answer 2

I had this problem with phantom-html-to-pdf (0.5.6).
In my case, my config was :
const pdf = require("phantom-html-to-pdf")({
// number of allocated phantomjs processes
numberOfWorkers: 3,
// timeout in ms for html conversion, when the timeout is reached, the phantom process is recycled
timeout: 10000,
// directory where are stored temporary html and pdf files
tmpDir: __dirname + "/tmp/",
phantomPath: "/usr/bin/phantomjs"
});
But my phantomPath was useless cause they're no executable at phantomPath in my case (we propably remove it for some reasons).
const pdf = require("phantom-html-to-pdf")({
// number of allocated phantomjs processes
numberOfWorkers: 3,
// timeout in ms for html conversion, when the timeout is reached, the phantom process is recycled
timeout: 10000,
// directory where are stored temporary html and pdf files
tmpDir: __dirname + "/tmp/"
});
My config without phantomPath works !
