Signal K installation, warnings (RPI 4)

[mba1959]

During installation of signal K, I have the below warnings, however it all seems to be working OK with NMEA 2000 input and using AVNAV as a client. however is it normal with those warnings? I am new to this....

pi@rpimba4c:~ $ sudo npm install -g signalk-server
npm warn deprecated [email protected]: This package is deprecated. Use require('node:util').isDeepStrictEqual instead.
npm warn deprecated [email protected]: Glob versions prior to v9 are no longer supported
npm warn deprecated [email protected]: This package is deprecated. Use the optional chaining (?.) operator instead.
npm warn deprecated [email protected]: Rimraf versions prior to v4 are no longer supported
npm warn deprecated [email protected]: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated [email protected]: This package is no longer supported.
