luarocks install gfx.js produces errors on my Ubunu 14.04

Here are some

npm http 304 https://registry.npmjs.org/fsevents/0.2.0 npm WARN optional dep failed, continuing fsevents@0.2.0

then when I launch

and the gfx doesn't apper to work properly, though it loads a browser on "http://localhost:8000/" which it is "Unable to connect" to. Or if I launch differently,

ihor@ihor-VirtualBox:~$ luajit -lgfx.start gm (GraphicsMagick) binary not found, please install (see www.graphicsmagick.org) [gfx.js] server started on port 8000, graphics will be rendered into http://localhost:8000 sh: 1: node: not found

Things look a bit different under root. Firefox is launchd here aswell displaying the same.

root@ihor-VirtualBox:/home/ihor# luajit -lgfx.go gm (GraphicsMagick) binary not found, please install (see www.graphicsmagick.org) [gfx.js] server started on port 8000, graphics will be rendered into http://localhost:8000 sh: 1: node: not found

Note this

Note when it thinks it is working successfully (under root)

but it's not, nothing happens, still "Unable to connect"

apt-get install graphicsmagick

from root

(Talking about the gm (GraphicsMagick) binary not found, please install (see www.graphicsmagick.org) error)

though previously, when the bugging happened, "luarocks list" showed me

graphicsmagick
   1.scm-0 (installed) - /home/ihor/torch/install/lib/luarocks/rocks

anyway.

This might be a worthy warning

npm WARN This failure might be due to the use of legacy binary "node"

Still get problems with

ihor@ihor-VirtualBox:~$ th -x [gfx.js] server started on port 8000, graphics will be rendered into http://localhost:8000
sh: 1: node: not found [gfx.js] clearing all cached graphics

(process:4116): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

So it looks like it tries to find "node". And still don't see anything initialized on my port. Might be just a problem with virtualbox, though.

gfx.js may be broken. You can use image.display(image.toDisplayTensor(YOUR TENSOR(s))) in qlua or you can just use iTorch

we moved everything past gfx.js, it indeed has so many install issues all the time.
