Answer 1

At least one of your problems is that your bootstrap package requires jQuery 1.9.1 or above, see the package.json file
"peerDependencies": {
"jquery": "1.9.1 - 3",
"popper.js": "^1.14.0" },
So all you really need to do is install jQuery and re-run npm install on your bootstrap package. So something like this should do it:-
# get back to the directory where your bootstrap package is
cd bootstrap-4.1.0
# install latest version of jQuery
npm i jquery
# re-install the bootstrap package
npm install
(I notice you are on Windows so do the equivalent of the above.) Go through all your packages that are in error or have a warning and make sure that they are installed.
