Support » Plugin: Debug Bar » 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.wordpress.org/plugin/debug-bar.0.8.2.zip...
    Unpacking the package...
    Installing the plugin...
    Plugin installed successfully.
    Success: Translations updates are not needed for the 'English (US)' locale.
    Activating '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$
    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 ?
