事件：'错误'
🌐 Event: 'error'
如果在写入或传输数据时发生错误，将会触发 'error' 事件。调用监听器回调时，会传入一个 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 'error' 事件被触发时，流将被关闭。
🌐 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，除了“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).
