Composer 和 Parsedown - Class 'UserFrosting\Parsedown' 未找到

Question

我成功地安装了 Parsedown 使用 composer 和

    "require": {
        ...
        "erusev/parsedown": "^1.6"
    },

并将class路径添加到自动加载部分

"autoload": {
    "classmap" : [
        "controllers", "middleware", "models", "plugins", "vendor/erusev/parsedown"
    ]
}

但是当我尝试执行这一行时...

    $Parsedown = new Parsedown();

...我最终遇到了这个错误：

Class 'UserFrosting\Parsedown' not found

运行 php composer.phar dump-autoload 没有帮助。

我在这里错过了什么？为什么在 UserFrosting 下需要 Parsedown - UserFrosting\Parsedown?

这里是完整的 composer.json:

}

看起来您正在尝试在具有命名空间 UserFrosting 的 class 中执行这行代码 $Parsedown = new Parsedown();。

在 php 文件的顶部添加一个 use 块，如下所示：use Parsedown;（这应该在名称空间声明之后），或者在 class 使用时的名称，例如：$Parsedown = new \Parsedown();。后者将开始在根命名空间中寻找这个 class。

您不需要将此 class 添加到 composer.json 文件的自动加载 classmap 部分。如果一个包被 composer 拉取，composer 会在运行 dump-autoload.

之后自动将所有内容添加到 autoloader
