Resolved [Duplicate] Uninstall memcached PHP extension error

[pegasx]

Server operating system version

Centos 7.9

Plesk version and microupdate number

Plesk Obsidian v18.0.57

By copying needed .h files I have managed to install php memcached extension. But it did not run properly so I have decided to uninstall from console and plesk, it gives the same error.

# /opt/plesk/php/7.4/bin/pecl uninstall memcached
PHP Fatal error: Uncaught Error: Cannot use object of type PEAR_Error as array in /opt/plesk/php/7.4/share/pear/PEAR/Dependency2.php:1036
