New to pio. I am getting the same error Detected unknown package espressif8266_stage.
I installed staging using command:
platformio platform install GitHub - platformio/platform-espressif8266: Espressif 8266: development platform for PlatformIO
Here is the output:
PlatformManager: Installing platform-espressif8266
espressif8266 @ e75d211 is already installed
PackageManager: Installing toolchain-xtensa @ ~1.40802.0
toolchain-xtensa @ 1.40802.0 is already installed

The platform ‘GitHub - platformio/platform-espressif8266: Espressif 8266: development platform for PlatformIO’ has been successfully installed!
The rest of packages will be installed automatically depending on your build environment.
but still getting the error. Where I am going wrong?
