I need help... Today i tried install the pocketmine in VPS (Cent OS 7). However i receive this alert: Code: [ERROR] Selected PHP binary (/usr/bin/php) does not satisfy some requirements. - Unable to find the pthreads (pthreads) extension. - Unable to find the YAML (yaml) extension. [ERROR] Please recompile PHP with the needed configuration, or refer to the installation instructions at http://pmmp.rtfd.io/en/rtfd/installation.html. If i execute Code: $ ./compile.sh or Code: $ ./install.sh i receive the same error. How to solve this?
