我用try catch块了iced coffee script.我调用不存在fake的对象不存在的方法a并期望捕获错误.

try
await db.find "79", defer c, d
a.fake()
catch error
console.log "error catched"
console.log error

但是db.find在控制台中调用函数a.fake()后抛出错误,但是它没有try catch按预期使用块.
如果我注释掉字符串await db.find "79", defer c, d......
db = require '../../call/db.iced'
try
# await db.find "79", defer c, d ############## commented out

我得到了用于管理node.js网站的永久脚本。
有时node.js网站会挂起并且响应时间超过 30 秒。事实上,网站已经关闭。然后快速治愈它是重新启动forever:

3中的脚本编号在哪里forever list?
可以自动制作吗?forever例如,如果响应时间超过 2 秒,是否有选项使其重新启动?
或者也许我必须运行外部脚本来检查响应时间并下降以重新启动挂起的forever脚本。
或者也许我需要在我的node.js网站中编写这个逻辑?
