PHPbrew连接超时

CURL无法使用phpbrew，如果我安装了php版本或php扩展或使用CURL的东西，脚本就不会完成。

有什么想法吗？

phpbrew ext install xdebug                                
Warning: Some extension won't be able to be built with php7. If the extension
supports php7 in another branch or new major version, you will need to specify
the branch name or version name explicitly.
For example, to install memcached extension for php7, use:
    phpbrew ext install github:php-memcached-dev/php-memcached php7 -- --disable-memcached-sasl
