Raspberry Pi:未设置 X11 DISPLAY 变量，但该程序执行了需要它的操作 [英] Raspberry Pi: No X11 DISPLAY variable was set, but this program performed an operation which requires it

问题描述

我正在使用 PuTTY 与 Raspberry Pi 建立套接字连接.我正在开发一个电视记分牌应用程序.我正在使用 WinSCP 将那些 .sh 文件复制到 Raspberry Pi 中.

I'm using PuTTY to have the socket connection with Raspberry Pi. I'm developing a TV scoreboard application. I'm using WinSCP to copy those .sh file into the Raspberry Pi.

当我运行一个脚本 ./timer.sh:

#!/bin/bash

java -jar /home/pi/ScoreBoard_app/Timer/Timer.jar

显示错误:

Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires     it.

我什至尝试设置DISPLAY=localhost:0.0.
它将显示 X11 服务器无法在localhost:10.0"上连接的错误.

I have even tried to set the DISPLAY=localhost:0.0.
It will show error that X11 server cannot connect on "localhost:10.0".

我也试过 localhost:1.0，但我得到同样的错误，它无法在localhost:1.0"上连接.

I also tried localhost:1.0, but I get the same error that it can't connect on "localhost:1.0".

推荐答案

您的 rasperry-pi 需要在 sshd_config

your rasperry-pi needs to enable X forwarding in sshd_config

你需要在你的电脑上运行一个X服务器，Xming是一个很好的开源X服务器

you need to have a X server running on your pc, Xming is a good open source X server

安装并启动Xming后，需要配置putty，设置x显示位置为localhost:0.0

after installing and starting Xming, you need to configure putty, set x display location as localhost:0.0
