“No display name” error when launching idle in cyg

问题:

I am getting a "Tlc error: no display name...etc" when I try to open python scripts in idle using Cygwin. I type the following:

idle python_script.py

Do I need to install another Cygwin package to make this work? Windows 7- recently installed. Thanks!!:)

The error means that the program cannot find a display to show the window on. To solve that you need to install X Windows system and then set the display environment variable to:

export DISPLAY=:0.0
