在作曲家自动加载器中找不到类

Question

我的composer.json里有这个

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",

    ],

        "psr-4": {
            "App\": "app/"
        }
    },
    "autoload-dev": {

        }
    },

            "@php artisan key:generate"
        ],
        "post-autoload-dump": [

            "@php artisan package:discover"
        ]
    },
    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    }
}

我的软件包的 php 文件在 laravel 安装中： /vendor/redbutton/text-image-alpha/src/

当我尝试调用文件时，我收到以下消息：

Class 'Class 'RedButtonTextImageAlphaTextImageAlpha' not found' not found

我用它来尝试调用类：

$image     = new RedButtonTextImageAlphaTextImageAlpha( 'some string' );

/vendor/redbutton/text-image-alpha/src/TextImageAlpha.php中的文件如下所示：

<?php
namespace RedButtonTextImageAlpha;
use RedButtonTextImageAlphaExceptions;
use RedButtonToolsObjects;

/**
 * TextImageAlpha class convert a text to image.
 *
 * @author Tomas Rathouz <trathouz at gmail.com>
 */
class TextImageAlpha
{
   // lots of code
}

这是我的第一个作曲家包，我真的不知道这里出了什么问题。有人可以向我解释我做错了什么吗？

好消息。我已经在Bitbucket上查看了您的软件包，并且您正在composer.json中这样做：

从composer.json中删除不必要的代码

我注意到在粘贴composer.json中手动添加了一些供应商文件。

"files": [
    "vendor/redbutton/text-image-alpha/vendor/autoload.php"
],

嵌套在/vendor中的/vendor没有意义，因为它可能会重复自动加载并破坏它。

此外，我在require部分中看不到redbutton/text-image-alpha，它应该在哪里。

如何以正确的方式添加包？

要安装软件包，只需调用作曲家：

composer require redbutton/text-image-alpha

仅此而已。

它应该出现在composer.json require部分中。作曲家将通过包composer.json的规则自动加载它 - 这里。

测试

我尝试了以下代码，并且正确找到了类：

<?php 
require __DIR__ . '/vendor/autoload.php';
$image = new RedButtonTextImageAlphaTextImageAlpha('some string');
var_dump($image);

有composer.json ：

{
    "require": {
        "redbutton/text-image-alpha": "^1.0"
    }
}
