WP-CLI – Fatal error: Cannot redeclare class Debug_Bar

  • I’m getting the following error when installing through WP-CLI:

    vagrant@example:/vagrant/site$ wp plugin install debug-bar --activate
Installing Debug Bar (0.8.2)
Downloading install package from https://downloads.www.ads-software.com/plugin/debug-bar.0.8.2.zip...

PHP Fatal error:  Cannot redeclare class Debug_Bar in /vagrant/site/wp-content/plugins/debug-bar/debug-bar.php on line 20
<br /><b>Fatal error</b>: Cannot redeclare class Debug_Bar in <b>/vagrant/site/wp-content/plugins/debug-bar/debug-bar.php</b> on line <b>20</b><br />vagrant@example:/vagrant/site$
    vagrant@example:/vagrant/site$ wp plugin activate debug-bar
PHP Fatal error:  Cannot redeclare class Debug_Bar in /vagrant/site/wp-content/plugins/debug-bar/debug-bar.php on line 20
<br /><b>Fatal error</b>: Cannot redeclare class Debug_Bar in <b>/vagrant/site/wp-content/plugins/debug-bar/debug-bar.php</b> on line <b>20</b><br />vagrant@example:/vagrant/site$

    But it seems like the easy fix is to just wrap the class in:

    if ( !class_exists('Debug_Bar')):
//...
endif;

    With that, it activates and deactivates normally.

    vagrant@example:/vagrant/site$ wp plugin activate debug-bar
Success: Plugin 'debug-bar' activated.
vagrant@example:/vagrant/site$ wp plugin deactivate debug-bar
Success: Plugin 'debug-bar' deactivated.

  • The only reason you should get that error, is that the plugin is already active. Could it be that the vagrant box you use comes with the Debug Bar plugin set up in the must-use plugins by default ?
