@niteraven7 You are gettin different error with same command php spark serve


strange

[lonnieezell]

You all fail to mention whether this is a new install or an existing install. Is this based on the main repo, or the app starter?

Looks like I still need to learn more about how the release scripts builds things out, since I did change where I thought the composer.json would come from but it didn't seem to propagate correctly. Change Kint version to 3.3 in composer.json and do a composer update. That should get it working for you.

[jlamim]

@lonnieezell I created a new installation to be able to verify this occurrence.

composer create-project codeigniter4/appstarter --no-dev

And I got the error mentioned at the opening of the Issue

[arif98741]

its fresh install using composer create

[niteraven7]

app starter here.
existing install rc4 updated to 4.0.0

@lonnieezell

I made a new installation from codeigniter4/framework via composer to be able to compare the structure of composer.json in relation to codeigniter4/appstarter and there are differences between the composer.json files.

In codeigniter4/appstarter there is no explicit mention of "kint-php/kint" in 'require'.

The installation with "codeigniter4/framework" worked correctly, but the installation with "codeigniter4/appstarter" presented the reported problem.

When trying to update the kint package via composer (composer require kint-php/php) to the latest stable version in an installation via "codeigniter4/appstarter" it gives an error saying:

Your requirements could not be resolved to an installable set of packages.

- codeigniter4 / framework 4.0.0 requires kint-php / kint ^ 2.1 -> satisfiable by kint-php / kint [2.1, 2.1.1, 2.1.2, 2.2, 2.x-dev] but these conflict with your requirements or minimum-stability.
- codeigniter4 / framework 4.0.0 requires kint-php / kint ^ 2.1 -> satisfiable by kint-php / kint [2.1, 2.1.1, 2.1.2, 2.2, 2.x-dev] but these conflict with your requirements or minimum-stability.
- codeigniter4 / framework 4.0.0 requires kint-php / kint ^ 2.1 -> satisfiable by kint-php / kint [2.1, 2.1.1, 2.1.2, 2.2, 2.x-dev] but these conflict with your requirements or minimum-stability.
- Installation request for codeigniter4 / framework ^ 4.0 -> satisfiable by codeigniter4 / framework [4.0.0].

From this I believe that the problem lies in the dependency on Kint installed by default when running the "composer create-project codeigniter4/appstarter project-name".

Perhaps an update to composer.json will be enough to solve the problem.

@lonnieezell the change you made in the framework repo will not work until you delete the old release (4.0.0) and make a new one. also only way to access the change right now is by switching to
"codeigniter4/framework": "dev-master"

[lonnieezell]

Yup. Working on it guys. Patience. :)

[lonnieezell]

Released 4.0.1 that fixed that. Unfortunately, it is now showing up an issue that I missed when reviewing our tests refactor last night. I won't have time until later tonight to fix that. A temporary fix is to remove the file: tests/_support/Commands/CommandsTestStreamFilter.php.
