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

取消配置：

composer config -g --unset repos.packagist

项目配置
仅修改当前工程配置，仅当前工程可使用该镜像地址：

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

取消配置：

composer config --unset repos.packagist

3、执行安装命令

composer require phpoffice/phpspreadsheet 1.15

composer require phpoffice/phpspreadsheet
指定命令运行的用户
 sudo -u nginx bash -c ‘/usr/local/bin/composer require phpoffice/phpspreadsheet‘  

4、composer安装

下载composer.phar文件

官网下载
https://getcomposer.org/download/1.8.0/composer.phar

sudo mv composer.phar /usr/local/bin/composer
chmod a+x /usr/local/bin/composer

参考

5、保持最新版

更新composer

经常执行 composer selfupdate 以保持 Composer 一直是最新版本

6、调试

composer 命令增加 -vvv 可输出详细的信息，命令如下：

composer -vvv require alibabacloud/sdk

7、安装成功
