Ioncube Loader on EE4 file is not accessible

currently I`ve installed EE4, but struggle to install ioncube loader. I am getting error
“The loader file /usr/lib/php/20170718/, listed in the configuration file, /usr/local/etc/php/php.ini, does not exist or is not accessible.”

Even file is located in folder mentioned above. Could you help me to sort this out, please?

Kind Regards
