Drush无法识别Drupal（找不到Drupal网站） [英] Drush can't recognize Drupal (No Drupal site found)
问题描述
我遵循了 http://docs.drush.org/en/master的说明/ install / 安装Drush（尝试全局和个人选项）
I have followed instructions on http://docs.drush.org/en/master/install/ to install Drush (tried both global and individual options).
当我到Drupal站点根目录并输入drush status时，我得到以下：
When I cd to the Drupal site root and type "drush status" I get the following:
Drupal version : 7.34
Site URI : http://default
PHP executable : /usr/bin/php
PHP configuration : /etc/php.ini
PHP OS : Linux
Drush script : /root/.composer/vendor/drush/drush/drush.php
Drush version : 7.0.0
Drush temp directory : /tmp
Drush configuration :
Drush alias files :
Drupal root : /var/www/site_dev
Site path : sites/default
当我输入drush cc all我得到：
When I type "drush cc all" I get:
No Drupal site found, only 'drush' cache was cleared.
'all' cache was cleared.
当我输入drush sqlc我得到：
When I type "drush sqlc" I get:
exception 'ReflectionException' with message 'Class Drush\Sql\Sql7 does not have a constructor, so you cannot pass any constructor [error]
arguments' in /root/.composer/vendor/drush/drush/includes/drush.inc:113

它使我觉得这个问题与MySQL有关系（因为状态不列出DB参数），但是我无法理解。
It strikes me that the problem has something to do with MySQL (because the status doesn't list the DB parameters), but I can't figure it out. Under sites there is only default folder, so it's not a multisite installation.
任何人都可以建议您有什么问题吗？
Can anyone advise what's wrong please?
更新
我已将PHP升级到5.5.27并重新安装Drush 7.0.0。
遵循一个建议这里我从主文件夹中删除了my.cnf，之后drush sqlc开始工作，但是当我输入drush -v -d status时，它给了我：
UPDATE I have upgraded PHP to 5.5.27 and reinstalled Drush 7.0.0. Following an advice here I deleted my.cnf from the home folder and after that "drush sqlc" started to work, however when I type "drush -v -d status" it gives me:

听起来可能是这个问题

Sounds like it could be this issue https://github.com/drush-ops/drush/issues/544
7.x不适用于PHP 5.3.3

基类SqlVersion类没有构造函数一个
的空数组被传递到其后代（Sql6或Sql7）。
The base class SqlVersion class does not have a constructor and yet an empty array is passed into its descendant (Sql6 or Sql7).
要做到这一点，这行
return $ reflectionClass-> newInstanceArgs（$ constructor_args）;
return $reflectionClass->newInstanceArgs($constructor_args);
应该替换为：
return！empty（$ constructor_args）？
$ reflectionClass-> newInstanceArgs（$ constructor_args）：
$ reflectionClass-> newInstanceArgs（）;
return !empty($constructor_args) ? $reflectionClass->newInstanceArgs($constructor_args) : $reflectionClass->newInstanceArgs();
您可以升级PHP v5.4或更高版本。
Alternatively you can upgrade PHP v5.4 or higher.
或者，您可以将drush降级为v6.x
Or, you can downgrade drush to v6.x
