我试图在作曲家上安装laravel软件包，我在cmd上使用了该代码：
composer global require laravel/installer
我面对
Composer could not find a composer.json file in C:\Users\SePehR\Documents
To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section
然后我去了https://getcomposer.org/“入门”，但是它并没有解决我的问题，而且我在论坛上观察到有关此问题的其他建议，但仍然没有解决，
