This error message usually occurs when trying to run a graphical application from a terminal without a graphical user interface. To solve this issue, you can try the following:
1. Make sure that you have a graphical user interface installed. If you are using a Linux server, you may need to install X11 or a similar package.
2. If you are accessing the terminal remotely, make sure that you have enabled X11 forwarding in your SSH client.
3. If you are running the application as a different user, make sure that you have permission to access the display. You can use the "xhost" command to grant permission to specific users.
4. If none of the above solutions work, try running the application as root. However, be careful when running applications as root as this can be a security risk.
