英文:
ERROR: Oops! Jetty doesn't appear to be installed
问题
特定错误：
** 错误：糟糕！Jetty 似乎没有安装在 /home/nicholas
尝试从控制台运行 /usr/share/jetty9/bin/jetty.sh restart。
就我个人而言，我不会期望 apt 将 Jetty 安装到 home，所以就目前而言，这是可以接受的。显然存在配置错误或者我没有正确启动它。
尝试启动 jetty：
nicholas@tech:~$
nicholas@tech:~$ /usr/share/jetty9/bin/jetty.sh restart
/usr/share/jetty9/bin/jetty.sh：第 250 行：cd：/opt/jetty9：没有那个文件或目录
** 错误：糟糕！Jetty 似乎没有安装在 /home/nicholas
** 错误： /home/nicholas/start.jar 不可读！

我按照 建议 添加了最后几行。
Jetty 是在 Ubuntu 上使用 apt 进行了 安装。
英文:
Specific error:
** ERROR: Oops! Jetty doesn't appear to be installed in /home/nicholas
when trying /usr/share/jetty9/bin/jetty.sh restart from the console.
I, for one, wouldn't expect apt to install Jetty to home, so that's fine so far as it goes. Clearly there's a misconfiguration or I'm not starting it properly.
trying to start jetty:
nicholas@tech:~$
nicholas@tech:~$ /usr/share/jetty9/bin/jetty.sh restart
/usr/share/jetty9/bin/jetty.sh: line 250: cd: /opt/jetty9: No such file or directory
** ERROR: Oops! Jetty doesn't appear to be installed in /home/nicholas
** ERROR: /home/nicholas/start.jar is not readable!

I added the last few lines as suggested.
Jetty was installed using apt on Ubuntu.
