Composer & Parsedown -类“UserFrosting\\Parsedown”未找到

Question

我设法使用composer安装Parsedown

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

并将类路径添加到autoload部分。

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

但当我试图执行这一行时..。

    $Parsedown = new Parsedown();

..。我最后犯了这个错误：

类“UserFrosting\Parsedown”未找到

运行php composer.phar转储-autoload没有帮助。

我在这里错过了什么？为什么在UserFrosting\Parsedown？- UserFrosting下预期会出现Parsedown

下面是完整的composer.json：

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

或者在php文件的顶部添加一个use块，比如：use Parsedown; (这应该在名称空间声明之后)，或者在使用它时在类名之前键入反斜杠，比如：$Parsedown = new \Parsedown();。后者将开始在根命名空间中查找该类。

您不需要将这个类添加到composer.json文件的autoload部分。如果一个包是由编写器提取的，那么在运行dump-autoload之后，编写器将自动将所有内容添加到自动加载程序中。
