command 'extension.build' not found

[zhubeilife]

When I use "Arduino Build", the VS code show command 'extension.build' not found.

I don't whether I set the Arduino path right? I run in Ubuntu 16.04, and the setting is showed below.

"arduino.idePath": "/home/bryan/Files/Programs/arduino-1.8.1/",
"arduino.libraryPath": "/home/bryan/Arduino/libraries"

Is it all right?

sorry, can not help with linux version, because I don't have a linux to develop and test, and in my README, I already said that linux version should work.

it seems 'extension.build' not found is not my problem, can you run other commands?
