i cant install Qt

[QtLover02]

Hello, good time. I'm having trouble installing Qt. When I run the command ./qt-unified-linux-x64-4.7.0-online.run, I encounter the following error:

qt.qpa.plugin: Could not find the Qt platform plugin "offscreen" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, xcb.

Aborted

Which platform are you trying to install on?
It looks like the platform doesn't have a screen.
In this case, you have to use command line options only.
See here.
