composer的安裝
一、重要說明：composer的安裝，依賴於phpstorm；phpstorm的使用依賴於php；因此在安裝composer以前，必須安裝和配置好php和phpstorm軟件；
1、有一部分composer在這里：C:\Users\Administrator\AppData\Roaming\Composer
二、下載網址：https://pkg.phpcomposer.com/
三、composer安裝的本質：就是下載"composer.phar"包；
1、下載網址：https://pkg.phpcomposer.com/
四、composer安裝的命令：
4.0、參考章節--如何安裝 Composer： https://pkg.phpcomposer.com/#how-to-install-composer
4.1、 php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');" //下載腳本"composer-setup.php"到當前目錄
4.2、 php composer-setup.php //執行安裝過程（下載最新的"composer.phar"）
4.3、 php -r "unlink('composer-setup.php');" //刪除腳本“composer-setup.php”
4.4、安裝方法2：復制文件“composer.phar”和“composer.bat”，粘貼在“php安裝根目錄”；
4.5、文件內容：composer.bat
@php "%~dp0composer.phar" %*
五、配置composer命令：
