DeprecationWarning: Calling an asynchronous function without callback is deprecated.

翻译: 不建议在不回调的情况下调用异步函数。

命令: node index.js 返回的信息有限.

(node:9276) [DEP0013] DeprecationWarning: Calling an asynchronous function without callback is deprecated.
at makeCallback (fs.js:127:12)
at Object.fs.unlink (fs.js:1049:14)
at D:\learning\myblog_v3\routes\signup.js:82:9
at <anonymous>
at process._tickCallback (internal/process/next_tick.js:188:7)

添加参数执行的参数, 使报错更加友好

node --trace-deprecation index.js

or:

node --throw-deprecation index.js
