宅基地的安装

我的整个日志 . 我对命令提示相当新鲜，我完全按照laravel文档要求我做，但问题只是从没有地方突然出现....我的目录是否正确？我通常在项目目录中运行所有命令，但laravel要求我“确保将〜/ .composer / vendor / bin目录放在PATH中，以便在终端中运行homestead命令时找到homestead可执行文件 . ”请帮忙 .

~\Composer\vendor\bin>composer global require "laravel/homestead=~2.0"

Changed current directory to ~/Roaming/Composer
