Problem in running the driver and app on linux system

[ADHATARAO]

I am using Ubuntu 18.04.3 LTS
Docker version 19.03.4, build 9013bf583a
I already tried to delete the container
and reinstalling docker.

I get errors even when I try to run script in databox-quickstart/blob/master/node/app/ directory

Following is the error generated when I try to run the example given in driver directory.
Reference link : https://github.com/me-box/databox-quickstart/blob/master/node/driver/README.md#writing-a-driver-in-node

Corresponding error :

cd src
sudo npm install
sudo npm start
