Solution

  • Explanation:

    The issue comes from the fact that the compiled view version under storage/framework/views is failing to evaluate $@clickPrevent.

    <?php $component = $__env->getContainer()->make(Illuminate\View\AnonymousComponent::class, ['view' => 'jetstream::components.dropdown-link','data' => ['href' => $href,'@click.prevent' => $@clickPrevent]]); ?>

    This has nothing to do with your current PHP version.

    Solution:

    I managed to locally reproduce the issue. Here is how I solved it.

    Steps:

    1. Publish the Jetstream Livewire components.

      Command:

      php artisan vendor:publish --tag=jetstream-views

    2. Open the file resources/views/vendor/jetstream/components/switchable-team.blade.php

      In the file contents,

      Instead of:

       <x-dynamic-component :component="$component" href="#" @click.prevent="$root.submit();"> ❌

      Use this:

       <x-dynamic-component :component="$component" href="#"> ✅

    Disclaimer:

    Note that this is a temporary solution. Everything works fine for me. As lamented by @IMSoP in a comment, I'm afraid it may affect some unknown functionality. I've opened an issue against the library here:

    switchable-team.blade.php compiled Jetstream component throwing an error: syntax error, unexpected token "@", expecting variable or "{" or "$"

    Update 10th/April/2022:

    Another "more stable" solution stated by @fabpl on the opened Github issue:

    I think it's the same bug like [2.x] Fix parse error caused by alpine shorthand on dynamic-component #1032

    Try to replace @click with x-on:click

    Addendum:

    The issue seems to have been introduced in laravel/jetstream v2.7.2. More specifically Use Alpine's @click.prevent for switching teams.

    The good news is that this has been resolved beginning from laravel/jetstream v2.7.3 onwards. More specifically [2.x] Fix parse error caused by alpine shorthand on dynamic-component.

    I just tagged v2.7.3 which should fix this. Thanks all 👍

    Hence, you may simply just upgrade your Jetstream version to v2.7.3 to get the fix. I.e:

    Command:

    composer update laravel/jetstream:2.7.3
