Error: Cannot find module 'firmata' #1777

Open dasamepu opened 2 years ago

dasamepu commented 2 years ago

Hello, I was trying to run the example but when I write in the command-line "node app.js" it shows me "Error: Cannot find module 'firmata'".

I'm not sure but I think it's because the file "C:\Users\user\AppData\Local\Temp\build123.tmp\StandardFirmata.cpp.hex" doesn't exist in my PC and in the Aduino IDE console log at bottom it shows me this file: "C:\Users\user\AppData\Local\Temp\arduino_build_560749/StandardFirmata.ino.elf".

Maybe that is the reason beacause is not working or not, but I'll be really thankfull if you help me. Error_Cannot_find_module_firmata

That particular error message isn't related to the Arduino code, it's just saying it can't find the node.js module "firmata". That should have been installed when you installed johnny-five so it's a bit of a mystery. Anything non-standard about your install process? Were there any errors when you ran npm i johnny-five? I assume this is running on Windows and connected to an Arduino via USB correct? If so try npm i firmata from within the proteusnode directory.

Yes, when I install johnny-five it looks like it wasn't intalled properly. npm_install_johnny-five

And when I install firmata it also shows me errors and says that I have should have to install python, but why if I won't use python? npm_intall_firmata_1 npm_intall_firmata_2

I have the same problem, at this moment could only put manually firmata library data to node_modules and it helps.
