  Class 'Vluzrmos\SlackApi\SlackApiServiceProvider' not found

Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

composer installというのは、package.jsonに指定されているパッケージをインストールするだけだと思っていたので、特定のクラスを探しにいって見つからない、ということが起こったことを不審に思った。

原因はこの箇所。

> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover --ansi

In ProviderRepository.php line 208:

@php artisan package:discover --ansiというコマンドでは、サービスプロバイダの読み込みをおこなっている。config/app.php に記載されたサービスプロバイダを読み込もうとして、存在しない Vluzrmos\SlackApi\SlackApiServiceProvider クラスを探している。

composer固有の動作ではなく、artisanコマンドを使用した際のエラーだったよう。

config/app.php

Barryvdh\Debugbar\ServiceProvider::class,

        /*
         * Slack API Service Providers...
         */
        Vluzrmos\SlackApi\SlackApiServiceProvider::class,
    ],

SlackApiがある。

個別にインストールしたら成功。
