[FIXED] How can I avoid unbound version constraints in composer?

Issue

I made a composer diagnose and I get the Warning:

WARNING require.symfony/serializer-pack : unbound version constraints () should be avoided require.symfony/webpack-encore-pack : unbound version constraints () should be avoided

How can I fix this issue?

Solution

See here: https://getcomposer.org/doc/faqs/why-are-unbound-version-constraints-a-bad-idea.md

Just define a suitable version after the required package like

symfony/serializer-pack:^4.0

which will prevent choosing ANY (maybe bc breaking) version.
