Many questions such as this one talk about this very annoying behavior on non-mac OS.
When I run npm install I want to remain aware of any warnings, but in Windows or Linux I would get this:
$ ./npm install
npm WARN deprecated chokidar#2.1.8: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
npm WARN deprecated fsevents#1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.
npm notice created a lockfile as package-lock.json. You should commit this file.

Notice that most WARN are caused by fsevents which is not available outside of macOS.
Some suggest to hide every warnings with:
npm --logevel=error install
Others advise to use:
npm install --no-optional --no-shrinkwrap --no-package-lock
But all these methods does not seem right to me. I only want to execute npm install and have a configuration file that would hide all optional dependencies that are not available on my operating system.
How can I do that?
npm install --no-optional prevents this warning.

How to fix it?
This behaviour is common when cloning a repo from github. Several packages have vulnerabilities and are not up-to-date. The 140 vulnerabilities include packages that are for production and development.
To check for vulnerabilities for production:
npm audit --production
To fix vulnerabilities for production:
npm audit fix --production
To fix every issue you can use npm audit fix, but be aware that some dependencies can be broken.

These are not errors, they are just warnings that you need to install the sub-dependencies of the given package yourself. React Navigation is installed successfully in this case and you can use it fine. You can try doing npm audit fix which will try to fix these warnings by installing the dependencies.

Apparently I can just ignore them, but I'm just curious if there's a way to not get these warnings? Configure npm somehow? Adding something to package.json? A flag somewhere?
You can silence the npm WARN upon installation by specifying what types of errors you want to see.
You can run npm --logevel=error install.
By using --loglevel=error you will only see npm ERROR and ignore any WARN
It's a warning, due to the operating system. fsevents run on mac os environment but in windows, it works as optional dependencies that are the reason behind your warning after all its not an error.
you can use https://github.com/paulmillr/chokidar instead of fsevents.
The problem relates to the "shrinkwrap" or package-lock.json which gets persisted after every package manager execution. Subsequent attempts keep failing as this file is referenced instead of package.json.
Adding these options to the npm install command should allow packages to install again.
--no-optional argument will prevent optional dependencies from being installed.
--no-shrinkwrap argument, which will ignore an available package lock or
shrinkwrap file and use the package.json instead
.
--no-package-lock argument will prevent npm from creating a package-lock.json file.
The complete command looks like this:
npm install --no-optional --no-shrinkwrap --no-package-lock
you can look into following answer npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents#1.0.14
