Laradock環境におけるClass 'Pusher' not found のエラーについて

Last updated at Posted at 2021-06-10

#はじめに
Laradock環境でLaravelアプリに通知機能を付けたい方向けに、タイトルのエラーが生じた場合の対処について記載しました。

#Pusherの登録と.envの記述を済ませた後...

laradockディレクトリ下で以下を実行
$ docker-compose exec workspace composer require pusher/pusher-php-server

すると以下の表示が、、、

Fatal error: Allowed memory size of 1610612736 bytes exhausted 略

単純に容量の問題かな?と思い、以下を実行してコンテナ内へ
$ docker-compose exec workspace bash

コンテナに入り、root@xxx:/var/www/html下で以下を実行
$ COMPOSER_MEMORY_LIMIT=-1 composer require pusher/pusher-php-server

しかし上手くいかず何故か
killedで強制的に追い出される、、、

#composerコマンドはLaradock下ではなくLaravel下で
ここでlaradock下で実行するのが適切でないのでは?と思い、laravelディレクトリ下で以下を実行
$ composer require pusher/pusher-php-server

すると以下の表示が、、、

Problem 1
    - Root composer.json requires barryvdh/laravel-debugbar ^3.6, found barryvdh/laravel-debugbar[v3.6.0, v3.6.1] but the package is fixed to v3.5.7 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

どうやらcomposer.lockに記述されているbarryvdh/laravel-debugbaのバージョンがv3.5.7では噛み合わず、v3.6系に変えてくれ、ということらしい。

composer.lockに記述を以下のように書き換えた

"packages-dev": [
        {
            "name": "barryvdh/laravel-debugbar",
            "version": "v3.6.1",         //v3.5.7からv3.6.1へ書き換え
            "source": {
                "type": "git",
                "url": "https://github.com/barryvdh/laravel-debugbar.git",
                //略
            },

結果、以下が通り、Class 'Pusher\Pusher' not foundの問題が解決!!!
$ composer require pusher/pusher-php-server --with-all-dependencies

以上です。
