Question

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将这些.sh文件复制到Raspberry Pi中。

我正在运行脚本./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.

我甚至试图设置DISPLAY=localhost:0.0 它将显示X11服务器无法在“localhost：10.0”上连接的错误。

我也试过了localhost:1.0，但是我得到的错误是无法连接“localhost：1.0”。

你的rasperry-pi需要在sshd_config

中启用X转发

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

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

了解详情，请搜索xming putty rasperry pi

Raspberry Pi：没有设置X11 DISPLAY变量，但是该程序执行了需要它的操作
