Answer 1

You seem to be running into a permissions issue. one thing that I always do is use:

sudo

that is on Mac. On Windows, you should be able to use:

--force at the end of your statement.

Answer 2

for windows : I tried to fix this problem by updating the node.js and installing express globally by running following command:- npm i -g express
