Hyperledger Explorer installation fails

Question

I have been trying to install Hyperledger Explorer onto the AWS instance of Hyperledger Fabric (1.0). I am referring to the installations steps mentioned at https://github.com/hyperledger/blockchain-explorer, which are mentioned below too.

cd blockchain-explorer/app/test

npm install

npm run test

cd blockchain-explorer

npm install

cd client/

npm install

npm test -- -u --coverage

npm run build

The command npm run test has been failing with the following error. Any hints?
