@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

more composer.json { "name": "codeigniter4/appstarter", "type": "project", "description": "CodeIgniter4 starter app", "homepage": "https://codeigniter.com", "license": "MIT", "require": { "php": ">=7.2", "codeigniter4/framework": "^4@rc" }, "require-dev": { "mikey179/vfsstream": "1.6.*", "phpunit/phpunit": "^7.0" }, "scripts": { "post-update-cmd": [ "@composer dump-autoload" ] }, "support": { "forum": "http://forum.codeigniter.com/", "source": "https://github.com/codeigniter4/CodeIgniter4", "slack": "https://codeigniterchat.slack.com" } }

@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

### codeigniter4/appstarter Requires php: >=7.2 codeigniter4/framework: ^4.0

@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.

[enix-app]

Me too, on Linux Mint.

[arif98741]

@enix-app Kint\Renderer not found in 4.0.1 but new bug appeared. hope it will be fixed soon.

[lonnieezell]

@arif98741 That was mentioned by two comments previously. :)

Copy the file:

https://raw.githubusercontent.com/codeigniter4/CodeIgniter4/develop/app/Config/Kint.php

Into the file "app/Config/Kint.php"

When updating from composer, this file is missing since it's new. This fixed it for me.

[lonnieezell]

Version 4.0.2 released that should fix all of this for a new install. Sorry about the release issues today.

[vrochanet]

Thanks for your work..

[lnavarroa]

Hi, I have the same problem, but i solved it by rename system/ThirdParty/Kint/kint.php to system/ThirdParty/Kint/Kint.php

[arif98741]

@lnavarroa great. But 4.0.2 already fixed that issue.

[lonnieezell]

While updating the filename works, the correct solution is to update Composer to update your version from 2.x to 3.x like the framework has done, and copy over the new app/Config/Kint.php to your application.

If you got this error with CodeIgniter v4.3, See https://codeigniter4.github.io/CodeIgniter4/installation/upgrade_430.html#config-files
