Java、Selenium、Debian for Raspberry Pi 4、geckodriver 错误打印垃圾

Question

我正在制作一个使用 Selenium 访问网页和检索数据的 Java 程序，它适用于 Windows、纯 Debian 和 Ubuntu 但是当我运行它在我的 Raspberry Pi 4 的 Debian 的 RPI4 上，geckodriver 给出了神秘的错误并且程序崩溃了。

报错如下：

该程序还创建了这个文件：''$'[=13=]12[=13=]2''@@'$'04''y@8'$'\a''@'$'52[=13=]1[=13=]5''@@t'$'2''6t'$'2''6'，但我自己没有编写该文件。程序运行时不会出现这种情况，只有当程序崩溃时才会出现这种情况。

可能是它不起作用，但我想知道答案。 geckodriver 正确地在程序内的 PATH 中并且是可执行的另外，firefox-esr 和 default-jre。

Answer 1

关于使用时打印的“乱码”
'gekodriver'，可能是因为它不适用于平台
(硬件+operating_system)你正在使用?
关于

Exception in thread "main" org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:29555 Build info: version: 'unknown', revision: 'unknown', time: 'unknown' System info: host: 'raspy', ip: '192.168.1.33', os.name: 'Linux', os.arch: 'aarch64', os.version: '5.9.0-0.bpo.5-arm64', java.version: '11.0.9.1'

这表明在 tcp6 ip 协议上没有监听 29555。

以上只是猜测，您可以尝试调查，直到出现更知情的人。
