每當我本地打開safiri的時候，本地的koa項目就會崩潰，不知道是啥情況。。Listeningon:8000/Users/lmn/project/u-pain-i-guess/node_modules/koa/lib/application.js:133constonerror=err=>ctx.onerror(err);^TypeError:ctx.onerrorisnotafunctionatArray.onerror(/Users/lmn/project/u-pain-i-guess/node_modules/koa/lib/application.js:133:34)atlistener(/Users/lmn/project/u-pain-i-guess/node_modules/on-finished/index.js:169:15)atonFinish(/Users/lmn/project/u-pain-i-guess/node_modules/on-finished/index.js:100:5)atcallback(/Users/lmn/project/u-pain-i-guess/node_modules/ee-first/index.js:55:10)atServerResponse.onevent(/Users/lmn/project/u-pain-i-guess/node_modules/ee-first/index.js:93:5)atemitNone(events.js:91:20)atServerResponse.emit(events.js:188:7)atonFinish(_http_outgoing.js:592:10)at_combinedTickCallback(internal/process/next_tick.js:73:7)atprocess._tickCallback(internal/process/next_tick.js:104:9)上面這串是報錯信息，serverlisten在8000端口我嘗試在代碼里進行添加app.use(bodyParser).use(router.routes()).use(router.allowedMethods()).on('error',console.error)app.onerror=console.error仍然這樣。。求大大解答。
