Arduino installa a board and the compiler doesn't recognise it.
i have written code program , compiled it, installed , run it. ok
some time later, 2 weeks, when ran error.
when come compile program error
board nodemcu (platform esp8266, package esp8266) unknown
error compiling board nodemcu 0.9 (esp-12 module).
e.g. the "tools- board selection" identifies board board "nodemcu 0.9 (esp-12 module)"
programmer: "arduinosp" seems correct.
no compilation carried out straight board error.
is compiler error?

the "board ... unknown" error occurs when boards manager installation of different version of hardware package fails uninstall previous version. here's how solve it:
- click link on line following file > preferences > more preferences can edited directly in file. open arduino15 folder.
- navigate packages/esp8266/hardware/esp8266 folder.
- you see 2 folders. 1 named version of package have installed, other named version of package had installed. delete folder previous version name. please careful when deleting things on computer. when in doubt up!
