composer

国内互联网某种神秘的力量让Composer变得越来越不稳定。 如果此种情况已经严重影响您的心情，请尝试在您的composer.json添加以下代码

{ "repositories": [ { "packagist": false }, { "type": "composer", "url": "https://packagist.phpcomposer.com" } ] }

通过下面的命令，您可以观察速度提升的效果

$ composer update -vvv

但是Composer我也安装不了啊喂～

我们为composer installer也做了镜像，您可以尝试：

$ curl -sS https://github.com/52fhy/composer/raw/master/bin/installer | php

如果没有安装curl，尝试以下命令（PHP你总得装吧喂～）

$ php -r "readfile('https://github.com/52fhy/composer/raw/master/bin/installer');" | php

当然，如果您不需要检查运行环境，也可以直接下载（一般来说直接下载就可以用）:

https://github.com/52fhy/composer/raw/master/bin/Composer-Setup.exe
https://github.com/52fhy/composer/raw/master/bin/composer.phar

官网地址： https://getcomposer.org/Composer-Setup.exe
https://getcomposer.org/composer.phar
