Создание картинки в nodejs

Задача очень проста, создать картинку, с какимто фоном, и каким то текстом по центру. После перевести в буффер.

Пробовал через graphicsmagick. Не получилось ни так:

var gm = require('gm');
var img = gm(200, 400, "#000000");
img.drawText(10, 50, "TEXT");
img.toBuffer((err) => {
    console.log(err);
});

err:

Error: Stream yields empty buffer

Ни так:

var fs = require('fs');
var gm = require('gm');
var img = gm(200, 400, "#000000");
img.drawText(10, 50, "TEXT");
img.write("./brandNewImg.jpg", (err) => {
    console.log(err);
 });

err:

Error: Could not execute GraphicsMagick/ImageMagick: gm "convert" "-size" "200x400" "xc:#000000" "-draw" "text 10,50 \"TEXT\"" "./brandNewImg.jpg" this most likely means the gm/convert binaries can't be found
