一、网络设置，保证板卡可以上外网。

root@elf2-desktop:/home/elf# nmcli con mod 'Wired connection 1' ipv4.method manual ipv4.addresses 10.10.19.45/24 ipv4.gateway 10.10.19.254 ipv4.dns 8.8.8.8 connection.autoconnect yes

root@elf2-desktop:/home/elf# nmcli con up 'Wired connection 1'

Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)

二、安装PYQT5

elf@elf2-desktop:~$ sudo apt install python3-pyqt5 pyqt5-dev-tools

三、测试例程

import sys

from PyQt5.QtWidgets import QApplication, QWidget

if __name__ == '__main__':

    app = QApplication(sys.argv)

    window = QWidget()

    window.setWindowTitle('PyQt5 Test')

    window.setGeometry(100, 100, 300, 200)

    window.show()

    sys.exit(app.exec_())

四、执行环境变量，测试应用

elf@elf2-desktop:~$ export DISPLAY=:0.0

elf@elf2-desktop:~$ python3 c.py
