事件：'error'
¥Event: 'error'
如果在写入或管道数据时发生错误，则会触发 'error' 事件。监听器回调在调用时传入单个 Error 参数。
¥The 'error' event is emitted if an error occurred while writing or piping
data. The listener callback is passed a single Error argument when called.
除非在创建流时将 autoDestroy 选项设置为 false，否则当触发 'error' 事件时将关闭流。
¥The stream is closed when the 'error' event is emitted unless the
autoDestroy option was set to false when creating the
stream.
在 'error' 之后，除 'close' 之外不应再触发其他事件（包括 'error' 事件）。
¥After 'error', no further events other than 'close' should be emitted
(including 'error' events).
