在 GitLab 的 CI / CD 的 Pipelines 中，Build composer 失败

1、在 GitLab 的 CI / CD 的 Pipelines 中，Build composer 失败。如图1

$ php artisan key:generate

In DatabaseServiceProvider.php line 88:
                                   
  Class 'Faker\Factory' not found  
                                   

Cleaning up file based variables
ERROR: Job failed: command terminated with exit code 1

2、在本地环境搜索 Class ‘Faker\Factory’，确定 /vendor/fzaninotto/faker/src/Faker/Factory.php 是存在的。在本地环境执行：php artisan key:generate 成功。如图2

PS E:\wwwroot\object> php artisan key:generate
Application key set successfully.

3、查看 gitlab-runner 中的日志，if [ ! -x “vendor” ];then echo ‘vendor not exists’; composer self-update 2.1.14; composer install –prefer-dist –no-ansi –no-interaction –no-progress –no-scripts –no-dev; else echo ‘vendor exists’; fi。如图3

$ if [ ! -x "vendor" ];then echo 'vendor not exists'; composer self-update 2.1.14; composer install --prefer-dist --no-ansi --no-interaction --no-progress --no-scripts --no-dev; else echo 'vendor exists'; fi
vendor not exists
You are already using the latest available Composer version 2.1.14 (stable channel).

4、在本地环境执行 composer install –prefer-dist –no-ansi –no-interaction –no-progress –no-scripts –no-dev，然后再执行 php artisan key:generate。报错：In Application.php line 679: Class ‘Barryvdh\Debugbar\ServiceProvider’ not found。原因应该在于本地环境与线上环境的配置项有差异。

PS E:\wwwroot\object> php artisan key:generate

In Application.php line 679:

  Class 'Barryvdh\Debugbar\ServiceProvider' not found

5、在本地环境执行 composer install –prefer-dist –no-ansi –no-interaction –no-progress –no-scripts，然后再执行 php artisan key:generate。不再报错。由此确认原因在于 –no-dev 的添加导致了流水线失败。–no-dev: 跳过 require-dev 字段中列出的包。在 composer.json 的 require-dev 配置中，存在 “fzaninotto/faker”: “^1.4″。

    "require-dev": {
        "fzaninotto/faker": "^1.4",
    },

6、将 require-dev 配置中的 “fzaninotto/faker”: “^1.4” 移至 require 配置中。不再报错。
