node.js - 了解 Node 中 console.trace() 的输出

Question

从命令行输入 console.trace() 将输出:

at repl:1:10
at REPLServer.eval (repl.js:80:21)
at Interface.<anonymous> (repl.js:182:12)
at Interface.emit (events.js:67:17)
at Interface._onLine (readline.js:162:10)
at Interface._line (readline.js:426:8)
at Interface._ttyWrite (readline.js:603:14)
at ReadStream.<anonymous> (readline.js:82:12)
at ReadStream.emit (events.js:88:20)
at ReadStream._emitKey (tty.js:309:10)

有人可以快速带我度过这个烂摊子吗？

这是当前堆栈的打印结果。显然你打了console.trace()来自 eval() 调用的某个脚本在repl.js (line 80, column 20) ，由 repl.js line 182 调用，由 events.js (line 67) 调用等等。你必须从上到下阅读。
