I keep getting the following error:

Error: write EPIPE
at errnoException (net.js:901:11)
at Object.afterWrite (net.js:718:19)

When i run the following function:

    router.route('/certificationService')
    .post(function (req, res) {
        var html = null,
            certificate = req.body.certificate,
            lang = req.body.lang,
            now = new Date(),
            dd = now.getDate(),
            mm = now.getMonth() + 1,
            yyyy = now.getFullYear();

        if (dd < 10) dd = '0' + dd;
        if (mm < 10) mm = '0' + mm;

        switch (lang) {
            case 'da':
                var text = {
                    title: 'Certifikat',
                    first_line: 'Dette certifikat er givet til',

                break;
            case 'en':

                break;
            case 'no':

                };
                break;
            case 'de':
                var text = {
                    title: 'Zertifikat',
                    first_line: 'Dieses zertifikat wird eine für gegebene',

                };
                break;
            default:
        }

        var data = {
            firstname: certificate.user.profile.firstname,
            lastname: certificate.user.profile.lastname,
            organization: certificate.user.organization.name,
            module_name: certificate.name,
            medal: env + certificate.medal.image_path,
            score: certificate.score,
            date: dd + '-' + mm + '-' + yyyy,
            show_score: certificate.show_score,
            description: certificate.text,
            company_logo: env + req.body.organization.logo_file_name,
            company_name: req.body.organization.name,
            text: text
        };

        // rendering the ejs file
        ejs.renderFile('./templates/certificate.ejs', {data: data}, function (err, result) {
            if (result) {
                html = result;
            } else {
                res.end('An error occurred: ' + err);
                console.log(err);
            }
        });

        var options = {
            filename: './user_resources/certificate/' + certificate.user.id + '/' + certificate.name.replace(/ +?/g, '_') + '.pdf',
            format: 'A4',
            orientation: 'portrait',
            type: "pdf",
            timeout: 30000
        };

        pdf.create(html, options).toFile(function (err, res) {
            if (err) return console.log("This is where it goes wrong"+ err);
            console.log(res);
        });

        var file = {
            originalname: certificate.name.replace(/ +?/g, '_') + '.pdf',
            path: './user_resources/certificate/' + certificate.user.id + '/'
        };

        var media = new Media(file, './user_resources/certificate/' + certificate.user.id + '/');

        var token = jwt.encode({
            mediaObject: media
        }, require('../secret')());


        res.status(200).json(token);
    });

So i tried to look around to find a solution and someone said:

Make sure both imagemagick and graphicsmagick are installed on your machine.

So ive installed it using the following:

$ sudo add-apt-repository ppa:dhor/myway
$ sudo apt-get update
$ sudo apt-get install graphicsmagick

However without any luck.

The following are the dependencies of my module:

    var fs = require('fs'),
    jwt = require('jwt-simple'),
    pdf = require('html-pdf'),
    path = require('path'),
    ejs = require('ejs'),
    async = require('async'),
    DataTypes = require("sequelize"),
    PDFKit = require('pdfkitjs'),
    gm = require('gm').subClass({imageMagick: true}),
    ffmpeg = require('fluent-ffmpeg'),
    sys = require('util'),
    exec = require('child_process').exec,

I really hope some of you are able to help me out!

You will get this error in some Os. To fix this for any Os, just specify the phantomjs:

var phantomjs = require('phantomjs');
var options = {
    phantomPath: phantomjs.path,
    filename: './user_resources/certificate/' + certificate.user.id + '/' + certificate.name.replace(/ +?/g, '_') + '.pdf',
    format: 'A4',
    orientation: 'portrait',
    type: "pdf",
    timeout: 30000
};
