找不到命令 cim。 Drush 无法查询数据库

Question

当在 Drupal 8 中执行运行ning drush cim 命令时，出现以下错误：

Command cim was not found. Drush was unable to query the database. As a result, many commands are unavailable. 
Re-run your command with --debug to see relevant log messages.

当我运行 drush cim --debug 显示以下内容时：

$ drush cim --debug

Answer 1

请在运行 drush cim 命令之前运行此命令 drush config-import。

更多信息请参考此link here 我希望它能解决你的问题。

Answer 2

就我而言，我只是没有启动虚拟服务器 (wamp)。

Answer 3

您可能（像我一样）正在尝试将所有导出的配置从某些 existing-site（从这里引用为 example.com）导入您的本地（localhost/PROJECT_NAME）进行开发原因，但目前（2019 年年中）不直接支持，您必须先导入数据库，详情请参见下文。

步骤：

从您的 existing-site（例如 example.com/admin/config/development/backup_migrate）导出和下载数据库。
在你的本地，确保你有足够的 RAM（可能关闭一些程序）。
创建您的本地数据库 (DATABASE_NAME) 并使用 PhpMyAdmin（或类似的东西，例如 http://localhost/phpmyadmin/）导入之前导出的数据库。
确保 settings.local.php 文件存在（在 ./sites/default/settings 目录中），当它不存在时创建它并配置它，例如：

<?php
$databases['default']['default'] = [
  'database' => 'DATABASE_NAME',
  'username' => 'root',
  'password' => '',
  'prefix' => '',
  // 'collation' => 'utf8mb4_general_ci',
  'host' => '127.0.0.1',
  'port' => '3306',
  'namespace' => 'Drupal\Core\Database\Driver\mysql',
  'driver' => 'mysql',
];

$settings['drupal_env'] = 'dev';
// Location of the site configuration files:
//  (Path used by "drush config-export" command)
# $config_directories['sync'] = '../config/d8_sync';

确保 settings.php 文件存在（在 ./sites/default 目录中），并且它包含上述 settings.local.php 文件（将附上我的默认 settings.php 文件）。
Goto localhost/PROJECT_NAME/core/install.php?rewrite=ok&langcode=en&profile=standard&continue=1 link（只是为了确保它显示 Drupal 已经安装）。
运行 drush cr（它现在应该可以工作并清除缓存）。

`settings.php` 文件:

这是我的默认 settings.php 文件，其中应包含 settings.local.php（如果存在）。
