Answer 1

This worked for me -

npm i -g npm@3.10.10

Answer 2

In your package.json file search for "dependencies" and editing it to show as

  "dependencies": {
     //same lib
    "jquery": "^1.9.1",
  },

or run this command from cmd

npm i jquery@1.9.1 --save

Answer 3

Just do as it says:

npm i jquery@1.9.1 --save

the option --save is to save this dependency to your project.

Answer 4

I had the same problem and this is the solution:

npm install bootstrap jquery popper.js --save

The system automatically resolves the references for you.
