V0.9.3 via visual studio/platformio fail

Hi, I download V0.9.3 and only modified the platformio.ini File by remmoving the “;” in front of default_envs = nodemcuv2-rf to select eactly this config.

even cleaned the Env. during build I get this:
"

What am I doing wrong?

I tried as well another config with BLE instead of RF but same result.

I did not find a fitting Category, hence left this field open.

I hope someone could help me here.
