Resolve Drush command terminated abnormally due to a unrecoverable error

Today, when you use Drush, you suddenly find that you cannot use it, prompting for errors:

Drush command terminated abnormally due to a unrecoverable error. [ERROR]

After testing, not drush configuration problem, nor Drupal kernel problem, is that I write a module hook_init () function is jump caused, leading to drush into the dead loop.

Drush command terminated abnormally due to a unrecoverable error. [ERROR]
[0.19 sec, 21.9 MB] Judging from the above debug, Drush No problem, is the hook in Drupal caused.

Solving method
If you're in the same situation, check out a hook in your custom module, such as:

Hook_init
Hook_boot

Drush is run through the PHP CLI command-line mode, and the CLI's PHP configuration environment differs from the php.ini used by Apache. If access to the site is not a problem, there is a problem with access to the CLI, you write the hook code there is a problem.
