安装Composer与PsySH

一、Windows安装Composer

需要开启 openssl 配置：打开 php 目录下的 php.ini，将 extension=php_openssl.dll 前面的分号去掉就可以了。

https://getcomposer.org/Composer-Setup.exe

下载打开：

1、查看安装

Win+R-->cmd-->composer

出现以下即表示已安装

2、将composer换成国内镜像

composer config -g repo.packagist composer https://packagist.phpcomposer.com

若是国外镜像，运行composer global require psy/psysh会一直显示Changed current directory to C:/Users/Administrator/AppData/Roaming/Composer

二、Composer安装PsySH

1、安装

composer global require psy/psysh

2、运行

可在安装位置C:\Users\Administrator\AppData\Roaming\Composer查看

将C:\Users\Administrator\AppData\Roaming\Composer\vendor\bin加入系统环境变量PATH

三、Composer安装Thinkphp5

composer create-project topthink/think tp5 --prefer-dist  //tp5为项目名称

四、Composer 安装PHPUnit

composer global require phpunit/phpunit  // 全局安装在c盘
composer require  --dev phpunit/phpunit  // 或者在项目根目录安装

另外：Centos安装Composer

# php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"
# php composer-setup.php

//移动 composer.phar，这样 composer 就可以进行全局调用
# mv composer.phar /usr/local/bin/composer

# echo "export PATH=$PATH:/usr/local/bin" >> /etc/bashrc  

# source /etc/bashrc  

# composer -v 

//切换为国内镜像,出现黄色警告不影响操作
# composer config -g repo.packagist composer https://packagist.phpcomposer.com
//记得时常更新 composer
# composer selfupdate
