Problems upgrading Laravel 5.4 to 5.6

Question

I'm using Laravel Framework 5.4.32, and after following the instructions in the two upgrade guides for 5.5.0 From 5.4 , and 5.6.0 From 5.5 , and the consensus that it's safe to do an upgrade for both in one go, I went ahead with a composer upgrade , got a list of problems but no guidance on how to fix them:

When I ran php artisan --version afterwards, I got an error:

[Symfony\\Component\\Debug\\Exception\\FatalThrowableError] Call to undefined method App\\Console\\Kernel::load()

So something's changed, although the application continues to work.

Aside from adding $this->load(__DIR__.'/Commands'); to the "commands()" method in "Kernel.php", the main changes were in "composer.json", as advised in the two upgrade guides.

Any ideas?

Answer 1

The tcg/voyager package is the problem

tcg/voyager v0.11.14 requires illuminate/support ~5.3.0|~5.4.0

You're installing 5.6 but it needs 5.4.

Upgrade it to version 1.1
