解决Command pm-disable needs 错误 没安装pear错误

提示错误信息

Command pm-disable needs a higher bootstrap level to run - you will need to invoke drush from a more functional Drupal environment to run this    [error]
command.
The drush command 'dis module_filter' 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.
