Confluence “Hello World” Macro help - NPM install/start not working

Question

I am trying to make my first confluence macro and I am following the instructions laid out here: https://developer.atlassian.com/cloud/confluence/getting-started/?_ga=2.78735767.2027190294.1547046060-2004234667.1546438516

Currently, I am having trouble with steps 2 and 4; NPM install and NPM start:

Received the following errors:

Answer 1

run npm cache clean --force first, and then run npm install , then npm start

this should fix it..

-- OR delete the node_modules folder and re-run npm install

-- OR 1. npm cache clean --force

2. delete node_modules and package-lock.json ,

3. npm install
