Question

我正在尝试使用Symfony 3.1开发Web应用程序，我需要使用一些外部库，如Faker和Guzzle。但是，每当我尝试使用这样的作曲家安装它们时：

composer require fzaninotto/Faker

它总是会抛出这样的错误：

我是否真的需要使用第三方symfony捆绑包或如何“按原样”使用该库？

Answer 1

您似乎已经提供了一项＆＃34;服务＆＃34;在config_dev.yml中阻塞，这意味着没有安装捆绑包并与该配置相关联。

只需删除＆＃34;服务＆＃34;阻止，你应该没问题，因为干净安装symfony并运行

composer require fzaninotto/Faker

就像一个魅力。

Answer 2

您的config.yml文件中只是错字，您写的是service:而不是services:。

Answer 3

您可以使用像这样的作曲家自动加载第三方库

// composer.json
{
    // ...

    "autoload": {
        "psr-4": {
            "Custom\\Namespace\\": "relative/path/to/library"
        }
    }
}

路径必须相对于包根。

您可以在作曲家documentation中找到更多信息。
