Trying to run a Sage 9.0.9 Build

I have been passed a project which was created in sage 9.0.9.

The build is failing. When I run composer install I get the following errors:

Package roots/sage-lib is abandoned, you should avoid using it. No replacement was suggested.
Package soberwp/controller is abandoned, you should avoid using it. No replacement was suggested.
Package symfony/debug is abandoned, you should avoid using it. Use symfony/error-handler instead.
Package roots/sage-installer is abandoned, you should avoid using it. No replacement was suggested.

Carbon 1 is deprecated, see how to migrate to Carbon 2.

    You can run './vendor/bin/upgrade-carbon' to get help in updating carbon and other frameworks and libraries that depend on it.

I don’t really know what to do from here. Is this build simply aged out? How can I continue to support this client?

You had some answers the last time you asked this question

From this topic it doesn’t look like you have any Composer errors. You stated you’ve got a failing build, but didn’t provide any sort of details regarding that.

Thats a different question about a different project and a different issue - there I wanted to upgrade a project for php8 which i did do and it worked perfectly.

This issue has different errors and Im currently not trying to run it on php8 - that will be my next goal. First stage is just to get it to build.

What further information do you require about the build to understand the problem?

You provided us with notices for composer install, which is the package management system and not the build

…so where are the errors related to the build?

If you don’t have build errors and are just experiencing an error during the composer install, searching for that message brought me here:

You probably want to get this project moved over to PHP 8 in order to get it working
