手把手教你在国内用正确的姿势使用 composer

安装 composer 命令行工具

# 下载
curl -sS https://getcomposer.org/installer | php
# 移动且重命名
mv composer.phar /usr/local/bin/composer

实例操作记录：

bogon:~ zhoumengkang$ curl -sS https://getcomposer.org/installer | php
All settings correct for using Composer
Downloading...

Composer (version 1.6.4) successfully installed to: /Users/zhoumengkang/composer.phar
Use it: php composer.phar

bogon:~ zhoumengkang$ mv composer.phar /usr/local/bin/composer

使用镜像

因为访问国外比较慢，可以使用阿里云 developer.aliyun.com/composer 提供的镜像。

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

原理是修改了家目录下面的./.composer/config.json

实例操作记录：

bogon:~ zhoumengkang$ composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
bogon:~ zhoumengkang$ cd .composer/
bogon:.composer zhoumengkang$ ls
auth.json    cacert.pem    cache        config.json    keys.dev.pub    keys.tags.pub
bogon:.composer zhoumengkang$ cat config.json
{
    "config": {},
    "repositories": {
        "packagist": {
            "type": "composer",
            "url": "https://mirrors.aliyun.com/composer/"
        }
    }
}
bogon:.composer zhoumengkang$ pwd
/Users/zhoumengkang/.composer
