process.stderr


process.stderr 属性返回连接到 stderr (文件描述符 2) 的流。 它是 net.Socket(也就是 Duplex 流),除非文件描述符 2 指向文件,在这种情况下它是 Writable 流。

process.stderr 在一些重要的方面不同于其他 Node.js 流。 有关更多信息,请参阅进程 I/O 的注意事项

The process.stderr property returns a stream connected to stderr (fd 2). It is a net.Socket (which is a Duplex stream) unless fd 2 refers to a file, in which case it is a Writable stream.

process.stderr differs from other Node.js streams in important ways. See note on process I/O for more information.
