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”:
