【www.bbyears.com--php安装】
今天在一个服务器上安装了一个walle-web的项目，要使用composer来安装
由于服务器没有安装composer，先安装一下
centos安装composer
curl -sS http://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
composer update错误
在我更想这个项目的时候发现提示如下错误信息
Failed to decode response: zlib_decode(): data error
Retrying with degraded mode, check https://getcomposer.org/doc/articles/troubleshooting.md#degraded-mode for more info
Your requirements could not be resolved to an installable set of packages.
解决方法
执行命令
composer self-update
