I had this error when I used a version Arduino IDE 1.6.7. In version 1.6.5 all good.

may the same as #1377, #1387
try to delete the 2.0.0 and rc2 folder, and then install the rc2 new.

HaD the same error. Intuitively did the same as Links2004 suggested. Works for me.

On Mac OS X, the folder is located at
/Users/$USER/Library/Arduino15/packages/esp8266/hardware

I was face same problem. I fix that problem
Goto C:\Users\"Your Username"\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266
Now you will see two version. you need to delete old version then restart your arduino IDE.

After boards update you need to restart IDE.
Check there is no previous version in ....\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266

Very important that there is NO other directory than the esp distro in the folder being discussed Arduino15\packages\esp8266\hardware\esp8266.

Having even a hidden folder (.vscode) in there will generate the same compiler error. Hope this helps someone out.
