This is because you installed the Laravel installer with global, which makes it globally available for all projects and installs it to /home/.composer.
这是因为您使用 安装了 Laravel 安装程序global，这使得它对所有项目全局可用并将其安装到/home/.composer.
This should be all right because it is only Laravel's installerand not a Laravel projectwhich should be created in a later step (see below) and this should be installed in your /var/html/wwwthen.
这应该没问题，因为它只是 Laravel 的安装程序，而不是应该在后面的步骤中创建的 Laravel项目（见下文），并且应该安装在你的/var/html/wwwthen 中。
Run the following command in your /var/html/wwwto create a new project (doesn't need Laravel installer):
在你的/var/html/www项目中运行以下命令来创建一个新项目（不需要 Laravel 安装程序）：
composer create-project --prefer-dist laravel/laravel YourProjectName 5.2
or use the Laravel installer
或使用 Laravel 安装程序
laravel new YourProjectName
