Answer 1

You type npm view insted of npm install . Also you can add --save option

npm install underscore --save

What is the --save option for npm install?

Answer 2

as some other say, u looks having problem with network.. i've never try "npm view express" but in my case it give a list of all the repository and file .. are u sure u have installed node?

node -v

if u have something like v6.9.4 (this is my current version.. yours can be more recent)

try to create "package.json" using: npm init -y

and then: npm i --save express
