Error while loading swoole_async

When loading the swoole async I'm getting following error

PHP Warning:  PHP Startup: Unable to load dynamic library 'swoole_async.so' (tried: /usr/lib/php/20180731/swoole_async.so (/usr/lib/php/20180731/swoole_async.so: undefined symbol: swWebSocket_get_package_length), /usr/lib/php/20180731/swoole_async.so.so (/usr/lib/php/20180731/swoole_async.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
