Heroku部署：“ composer安装”过程因错误而失败

Question

我尝试使用以下命令将项目部署到Heroku：

git push heroku master

尽管在此之前它运行良好，但它给了我这些错误：

remote:  !     WARNING: There was a class not found error in your code
remote:

remote:  !     
remote:  !     The 'composer install' process failed with an error. The cause

这是composer.json文件：

    "type": "project",
    "description": "The Laravel Framework.",

        },
        "classmap": [
            "database/seeds",
            "database/factories"
        ]
    },
    "autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/"
        }
    },

        ],
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "@php artisan key:generate --ansi"
        ]
    }
}

我尝试了所有说明，并在终端中实现了这些命令：

撰写者更新 git add composer.json composer.lock

我确实知道错误出在哪里，因为我尝试了许多解决方案，甚至删除了post-create-project-cmd中的内容。

如果有人可以帮助我，我将不胜感激

Answer 1

我遇到了这个问题。尝试删除heroku bash上的所有文件

步骤

1. heroku run bash
2. ~$: rm -rf .*
3. ~$: rm -rf *

重新克隆（强制）

1. git push heroku master -f

如果它说已更新，那么您可以正常克隆~$: heroku git:clone -a <insert app name>
