Error compiling for NodeMCU 1.0 (ESP-12E module)

[Kepete]

I try to compile and upload it using the Arduino IDE and get an error like this:

Arduino: 1.8.4 (Mac OS X), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, 4M (1M SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

[nidayand]

And you have installed the dependencies? E.g. PubSubClient

[Kepete]

@nidayand Yes, Stepper_28BYJ_48, PubSubClient, ArduinoJson, WIFIManager, WbSocketsServer are all installed.

[Kepete]

Compiling some other examples(led blinking, WebSocketClient example etc) works, so it isn't a connection or board error.

[Kepete]

Problem solved. It didn't add the NidayandHelper.h file to the IDE, now compiled successfully. Issue can be closed.

@nidayand hi i cant upload the code, got this error, i got all the files, what could it be
