推荐答案

没有日志文件.每个node.js应用"都是一个单独的实体.默认情况下，它将错误记录到STDERR并输出到STDOUT.您可以在从外壳运行它时将其更改为登录到文件.

There is no log file. Each node.js "app" is a separate entity. By default it will log errors to STDERR and output to STDOUT. You can change that when you run it from your shell to log to a file instead.

node my_app.js > my_app_log.log 2> my_app_err.log

或者(推荐)，您可以手动或使用许多日志库之一在应用程序内部添加日志记录:

Alternatively (recommended), you can add logging inside your application either manually or with one of the many log libraries:

• 温斯顿
• log4js
• ...

• winston
• log4js
• ...
