我运行了 ./discourse-setup，回答了问题并等待。我的终端在以下行卡住：#<Thread:0x00005621595f3360@/var/www/discourse/lib/tasks/assets.rake:215 run> terminated with exception (report_on_exception is true):。唯一能释放终端的方法是关闭 SSH 连接并重新连接。
我对 Linux 只有基本了解。
使用 apt-get 更新系统并未带来任何改变。
我发现安装程序在 assets:precompile 任务处卡住。异常来自 /var/www/discourse/lib/tasks/assets.rake:227:in rescue in block (2 levels) in <top (required)>': undefined local variable or method'name' for main:Object (NameError)。

安装程序随后执行了一些任务，过程中未出现问题。但在流程结束时出现以下错误：
FAILED--------------------

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one
./discourse-doctor may help diagnose the problem.
