从昨天起我正在通过
创建一个laravel项目composer create-project laravel / laravel project_name
我收到这些建议信息。这是正常的还是让我搞砸了。
我在PHP 7.0.1中安装了Xampp。将wamp中的PHP选项从7.0.1切换到5.x.x（只有一个选项，不记得确切的选项）从那时起，无论是创建新项目还是通过comopser require命令添加包，我都会收到这些消息。我在Wamp中将PHP版本切换回7.0.1。卸载了wamp，但仍然有消息。不受欢迎的xamp，重新安装它但仍然收到这些消息。
symfony / var-dumper建议安装ext-intl（在时区转储中显示区域名称）
symfony / var-dumper建议安装ext-symfony_debug（）
symfony / routing建议安装doctrine / annotations（用于使用注释加载器）
symfony / routing建议安装symfony / config（用于使用一体化路由器或任何加载器）
symfony / routing建议安装symfony / dependency-injection（用于从服务加载路由）
symfony / routing建议安装symfony / expression-language（使用表达式匹配）
以及像这样的长列表
答案 0 :(得分：10)
这很正常。有些软件包可以提供建议，但Laravel应用程序不需要它们。这些包在某些情况下可能很有用，但确保不需要运行或创建Laravel应用程序，因此您可以安全地忽略这些消息。
