acutely your NPM install work and you install your package successfully these warning and error just say some package that's you use in project are deprecated and you can install new versions. and you can audit these with NPM audit. so just ignore this and resume you work:)

can't solve deprecation warnings

Every time I install a new package or when I run npm audit fix (--force), I get deprecation warnings which are not getting fixed. I deleted package lock and tried everything but nothing works. Seems also to be a global error since it doesn't matter in which of my projects I do that. I try updating vue-cli which worked.
Does somebody have a solution to that?

At first you need to initialize you npm package for package.json file.
using that command npm init -yes . Create a default package.json file.
Then need to install it globally using this command :
npm install parcel-bundler -g
Also you can try to save it in your package.json file.
npm install parcel-bundler -g --save-dev

Are you using ng new? What is your ng --version, are you sure you are up-to-date with Angular CLI as well? (Also, you should use at least Node LTS version (12.18 at the moment), check with node -v).
Also, try cleaning your cache:
npm cache clean --force
then try the command again.

How to install Angular2 universal when the docs on the site are outdated?

The maintainers at angular2-universal have not updated their site:
Problem 1)
typings install node express body-parser serve-static express-serve-static-core mime --ambient
typings ERR! deprecated The "ambient" flag is deprecated. Please use "global" instead
Problem 2)
typings install node express body-parser serve-static express-serve-static-core mime --global
typings INFO globaldependencies "express" lists global dependencies on "node" that must be installed manually
typings INFO globaldependencies "body-parser" lists global dependencies on "node" that must be installed manually
typings ERR! message Unable to find "node" ("npm") in the registry.
typings ERR! message However, we found "node" for 2 other sources: "dt" and "env"
typings ERR! message You can install these using the "source" option.
typings ERR! message We could use your help adding these typings to the registry: https://github.com/typings/registry

typings ERR! typings -v 1.3.3
typings ERR! If you need help, you may report this error at:
typings ERR! <https://github.com/typings/typings/issues>
How do I resolve? I am using a mac.

The solution is to install node separately with the --global flag, because it's the only one that needs to be installed globally.
typings install dt~node --global
typings install dt~express dt~body-parser dt~serve-static dt~express-serve-static-core dt~mime
EDIT :
You don't need angular universal for server side rendering anymore, as it is now part of angular core.

As of version 1.0 TypeScript Definition Manager made some updates ([see here][1]) which included deprecating the --ambient flag.
Usages of ambient are now global
That means in typings.json any ambientDependencies should be renamed globalDependencies and any ambientDevDependencies should be
renamed globalDevDependencies.
It also means --ambient is now --global
...
=> For more information, check this out.
[typings github]: https://github.com/typings/typings
[original answer]: Ambient flag is deprecated
Thus, you should use this pattern ↓
typings install dt~PackageName --save --global
ex) typings install dt~body-parser --global --save
Comment below, if you need more help.

With a couple of things changing across typescript and the universal team working overtime to updating universal to the latest releases of angular rc5 and rc6, things have fallen a bit behind on the documentation front.
If you want to get started quickly, checkout out the universal starter kit at https://github.com/angular/universal-starter that should work for you.
