Drush不能引导

Question

我使用Composer安装Drush 7，并在Windows上的XAMPP上创建了一个Drupal 8。

1. H:\xampp\htdocs\d8_test是Drupal根。
2. H:\xampp\htdocs\d8_test\sites\default\settings.php.是settings.php文件的位置

所有的drush命令都没有工作。所有的失败都有相同的错误：

H:\xampp\htdocs\d8_test>drush pmi
Command pm-info needs a higher bootstrap level to run - you will need    [error]

to invoke drush from a more functional Drupal environment to run this
command.
The drush command 'pmi' could not be executed.                           [error]

Drush was not able to start (bootstrap) the Drupal database.             [error]

Hint: This may occur when Drush is trying to:
 * bootstrap a site that has not been installed or does not have a
configured database. In this case you can select another site with a
working database setup by specifying the URI to use with the --uri
parameter on the command line. See `drush topic docs-aliases` for
details.
 * connect the database through a socket. The socket file may be
wrong or the php-cli may have no access to it in a jailed shell. See
http://drupal.org/node/1428638 for details.

Drush was attempting to connect to:
 Drupal version        :  8.0-dev
 Site URI              :  http://default
 Database driver       :  mysql
 Database username     :  root
 Database name         :  d8_test
 PHP executable        :  php.exe
 PHP configuration     :  H:\xampp\php\php.ini
 PHP OS                :  WINNT
 Drush version         :  7.0-dev
 Drush temp            :  Z:\Temp
 directory
 Drush configuration   :
 Drush alias files     :
 Drupal root           :  H:/xampp/htdocs/d8_test
 Site path             :  sites/default
 Active config path    :  sites/default/files/config_MoeSD5C7JSguok
                          xrBh4-UuwT_r9_jk2Z59QKdN-j9Zx9DIgHBy2dH8n
                          1rGOeKNJpaAAxBi4PzA/active
 Staging config path   :  sites/default/files/config_MoeSD5C7JSguok
                          xrBh4-UuwT_r9_jk2Z59QKdN-j9Zx9DIgHBy2dH8n
                          1rGOeKNJpaAAxBi4PzA/staging

我的settings.php的内容

$databases['default']['default'] = array (
  'database' => 'd8_test',
  'username' => 'root',
  'password' => '',
  'prefix' => '',
  'host' => '127.0.0.1',
  'port' => '3306',
  'namespace' => 'Drupal\\Core\\Database\\Driver\\mysql',
  'driver' => 'mysql',
);

注意，我的MySQL安装主机是127.0.0.1，而不是localhost。

还请注意，H:\xampp\php\被添加到我的PATH变量中，因此php.exe引用了H:\xampp\php\php.exe。

drush sql-connect的输出如下：

mysql --用户=root--密码=--数据库=d8_test--主机=127.0.0.1--端口=3306

Answer 1

drush sql-connect的输出为mysql --user=root --password= --database=d8_test --host=127.0.0.1 --port=3306。现在，当我直接执行这个命令时，它没有工作，因为系统路径中没有mysql.exe。因此，我将H:\xampp\mysql\bin添加到PATH (Windows中的环境变量)，然后它就起作用了！

Answer 2

确保安装了mysql客户端核心-5.5包。

关于Ubuntu：

sudo apt-get install mysql-client-core-5.5
