composer 安装

参考 https://getcomposer.org/download/

方法一：全局安装

打开命令行窗口，依次输入以下命令

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php

php -r "unlink('composer-setup.php');"

在 composer.phar 同级目录（C:\Users\Administrator）下新建文件 composer.bat ：

C:\Users\Administrator>echo @php "%~dp0composer.phar" %*>composer.bat

　　

二.局部安装

把这composer.bat  composer.phar 这2个文件剪切到php.exe目录下即可
