笔记

# 使用 Composer 镜像加速配置

  • Linux下全局安装 composer 方法
curl -sS https://getcomposer.org/installer | php  // 下载 composer
mv composer.phar /usr/local/bin/composer  // mv composer.phar /usr/local/bin/composer
  • 选项一：全局配置，这样所有项目都能惠及（推荐）；
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
  • 选项二：单独项目配置；
composer config repo.packagist composer https://mirrors.aliyun.com/composer/

# Composer 常用命令

  • composer install 根据 composer.json 里面的配置安装组件
    • --no-dev 跳过 require-dev 字段中列出的包
  • composer update 更新组件
  • composer dumpautoload 把自动加载写入自动加载的配置文件中
  • composer require predis/predis 1.0.* 安装组件，并指定版本
  • composer remove predis/predis 移除依赖

# Composer 其他命令

  • composer -v 查看当前版本
  • composer selfupdate 升级版本
  • composer config -gl 查看 composer 配置
  • composer config -g --unset repos.packagist 取消全局配置
  • composer config --unset repos.packagist 取消当前项目配置
  • composer clear-cache 清除本地缓存
  • composer update nothing 刷新 composer.lock 文件
  • composer -vvv predis/predis 打印调错信息
