Ao tentar executar o comando docker run -d -p 8080:3000 -v "C:\Users\gamep\Desktop\docker\exemplo-1:/var/www" -w "/var/www" node npm start
me é retornado o seguinte erro: C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: \"npm\": executable file not found in $PATH": unknown.
