php：composer的安装

composer的安装

 

 

 

 

一、重要说明：composer的安装，依赖于phpstorm；phpstorm的使用依赖于php；因此在安装composer以前，必须安装和配置好php和phpstorm软件；

　　1、有一部分composer在这里：C:\Users\Administrator\AppData\Roaming\Composer

 

 

 

二、下载网址：https://pkg.phpcomposer.com/

 

 

 

三、composer安装的本质：就是下载"composer.phar"包；

　　1、下载网址：https://pkg.phpcomposer.com/

 

 

四、composer安装的命令：

　　4.0、参考章节--如何安装 Composer： https://pkg.phpcomposer.com/#how-to-install-composer

　　4.1、 php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');" //下载脚本"composer-setup.php"到当前目录

　　4.2、 php composer-setup.php //执行安装过程（下载最新的"composer.phar"）

　　4.3、 php -r "unlink('composer-setup.php');" //删除脚本“composer-setup.php”

 

　　4.4、安装方法2：复制文件“composer.phar”和“composer.bat”，粘贴在“php安装根目录”；

 

　　4.5、文件内容：composer.bat

@php "%~dp0composer.phar" %*

 

 

 

五、配置composer命令：


　　5.1、把“composer.phar”和“composer.bat”复制到php的安装根目录“D:\tools\website\xampp\8012\php”


　　5.2、在cmd内，可以使用"composer命令":
