PHP作曲家自动加载未加载类 [英] PHP composer autoload not loading class

问题描述

我刚刚开始使用composer进行依赖项管理，并且很难弄清楚如何不遵循psr-4进行自动加载，因此我在这里提供建议.我有一个生成随机值的类，该类已经存在于包装专家中.项目结构如下(我已将composer.json文件标记为A和B):

I'm just getting started using composer for dependency management and I'm having a hard time figuring out how I'm not adhering to psr-4 for autoloading so I'm here for advice. I've got a class that generates random values that is already on the packagist. The project structure is the following (I've labeled the composer.json files A and B):

项目目录

  |classfile.php 
A |composer.json
  |vendor
   |autoload.php
    |ejfrancis
      |php-random-value
B       |composer.json
        |RandomValue.php        <--the class I want autoloaded    

composer.json A

composer.json A

{
    "require": {
        "ejfrancis/php-random-value": "dev-master"
    }
}

composer.json B

composer.json B

{
    "name": "ejfrancis/php-random-value",
    "description": "Secure random value generator.",
    "require": {
        "php": ">=5.3.0"        
    },
    "license": "MIT",
    "autoload": {
        "psr-4": {
            "ejfrancis\\" : ""
        }
    }
}

最后是RandomValue.php文件，该文件声明了ejfrancis命名空间

and finally the RandomValue.php file, which declares the ejfrancis namespace

namespace ejfrancis;

class RandomValue{
  //foo
}

运行应用程序时，出现错误找不到类RandomValue"，因此无法正确自动加载.我是否不遵守psr-4，还是我做错了其他事情?我还尝试仅使用"classmap" : ["RandomValue.php"]之类的作曲家类映射进行自动加载，但未成功. 感谢您的帮助

When I run the app I get an error 'class RandomValue not found', so it's not autoloading correctly. Am I not complying to psr-4, or is there something else I'm doing wrong? I've also tried autoloading just using a composer classmap like "classmap" : ["RandomValue.php"] to no success. Thanks for the help

更新:我已经在composer.json B文件上运行了"composer validate"，它肯定是有效的

Update: I've run 'composer validate' on the composer.json B file, it definitely is valid

推荐答案

将作曲家更改为"Namespace\\"并执行作曲家dump-autoload -o

Change in your composer to "Namespace\\" and do a composer dump-autoload -o
