最近用drupal做开发，想用一下console

按照官方提示的地址：https://hechoendrupal.gitbooks.io/drupal-console/content/zh_hans/getting/installer.html

安装完成后，到相应的网站目录执行drupal init 时提示要用以下两条命令执行composer安装

[ERROR] Drupal Console is not installed at:                                    
                                                                               
You must execute the following composer commands:

composer require drupal/console:~1.0 --prefer-dist --optimize-autoloader      
composer update drupal/console --with-dependencies

sudo第一条后，出现以下错误

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
                                                                           
 [Composer\Downloader\TransportException]

 ttps://getcomposer.org/doc/06-config.md#secure-http for details.            

百度找了好多，都是说用composer update就行！结果都扯蛋没用！

后来找到了解决方案：

sudo composer config -g repo.packagist composer https://packagist.phpcomposer.com

问题主要原因：是composer的源没有相应的zlib_docode，更新一个composer源就好！
