#43303 Hi,
I am also having a problem with Arduino 1.67 and also 1.68
Using ESP8266 stable release 2.1
When I try to compile I get the following error:
Arduino: 1.6.7 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Serial, 115200, 4M (3M SPIFFS)"

Board nodemcuv2 (platform esp8266, package esp8266) is unknown
Same with any board

Has anyone else had this problem and fixed it?
