Warning sebastian/resource-operations on installation

I'm having a warning when I try to install codeigniter 4 through appstarter. It's "Package sebastian/resource-operations is abandoned, you should avoid using it. No replacement was suggested." Should I ignore or there is a way to fix it?

You can safely ignore this warnings as <pre>sebastian/resource-operations</pre> is only used internally by <pre>phpunit/phpunit</pre> for unit testing. However, if you are using that package directly in your code, then you should discontinue using it.
