Problem “Build and install app” - Developer Studio FX 30

1

Hello
I start with Legato and Sierra Wireless IDE Developer Studio.
For the moment, I am trying to program the FX-30 with a basic application “Hello World” by following a tutorial “FSEgate of April 2017”.
When I “Build and install app”, I get an error message:

"HelloWorld Run
Execute 3 tasks
Connecting to device
Target is already connected
HelloWorld Build
Project contains error
Install HelloWorld
Can not find binary artifact for HelloWorld
Can not find binary artifact for HelloWorld
"
I’m looking for but I do not really understand.

Can someone help me ? thank you so much

To clarify, I think the problem comes from “Docker problem”.
When I go to Windows> Preferences> Docker, I have this warning:
“The ‘docker-compose’ command could not be located in C: \ Users \ Valentin \ VirtualBox VMs \ legato-docker-vm”
