原帖:如何修复 johnny 5 安装错误?

当我运行我的 JS 文件时,我收到此错误:

1637373588955 Available COM3 
1637373588956 Connected COM3 
1637373592592 Repl Initialized 
>> 1637373598958 Device or Firmware Error A timeout occurred while connecting to the Board. 

Please check that you've properly flashed the board with the correct firmware.
See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting

If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the board, wait approximately 11 seconds for complete reset, then run your program again. 
events.js:306
    throw err; // Unhandled 'error' event
    ^

我已经尝试安装不同的 Firmata 软件,但没有帮助。你怎么看?
