### 安装未发布版本
如果自制包没有发布在composer.json中写
`"minimum-stability": "dev",`
安装时使用命令
`composer require idcpj/talking_robot:dev-master`

## 使用composer
### 安装 composer
#### 全局安装
[各个版本的教程](https://pkg.phpcomposer.com/#how-to-install-composer)
centos
```
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
```
### 使用镜像
[中国全量镜像](https://pkg.phpcomposer.com/)
[阿里镜像](https://developer.aliyun.com/composer)
1. 在全局配置镜像(推荐)
在命令行中输入:
`composer config -g repo.packagist composer https://packagist.phpcomposer.com`
2. 修改项目镜像
在项目根目录
`composer config repo.packagist composer https://packagist.phpcomposer.com`
你也可以手动添加镜像地址到composer.json文件
```
"repositories": {
"packagist": {
"type": "composer",
"url": "https://packagist.phpcomposer.com"
}
}
```
3. 出现ssl 报错
参考此[网站](http://www.ituring.com.cn/article/261281)
### 初始化项目
如 `composer create-project easyswoole/app` 后在本地生成一个与 `github.com/easy-swoole/app`相同的项目
### 安装依赖
`composer install`
### 新增依赖
