Visualruby can't be run

Hi,

I am new to ruby and try to see it by start using visual ruby.

i installed ruby 2.3.1 -p112 and Glade 3.8.5 (A user interface designer
for GTK+ and GNOME) on my windows 7 OS.

after writing vr and clicking ENTER i got errors as in the jpg i
attached.

it seems that the installation is not perfect.

how can i solve the problem?
