There's something wrong with my arduino IDE that I can't figure out. I have a sketch for an ESP8266 Huzzah Feather that compiles just fine on my friend's machine but won't on mine. I've installed the latest boards from the board manager, installed the software drivers, but when I go to compile I get this error:
FindFirstFile C:\Users\user\AppData\Local\Temp\arduino_cache_417501: The system cannot find the file specified. Error compiling for board Adafruit Feather HUZZAH ESP8266.
I've checked that folder and no such file or folder exists. What cache is it referring to? Is there a way to clear the cache and start over? I can't find any option or menu that suggests there even is a cache.
I've uninstalled and re-installed the IDE twice. I've double checked that the boards are installed and the right board is selected. What else could I be missing? It was working fine a few months ago but now it just won't work.
