[Errno 2] No such file or directory

Hello, I come from https://exchange.checkmk.com/p/php-fpm, thank you very much for making this plugins available, I installed it but I have a problem that I could not solve, I have this error.

[root@te-aai-34-03 plugins]# ./php_fpm_pools
<<<php_fpm_pools>>>
[Errno 2] No such file or directory
[root@te-aai-34-03 plugins]#

my config file is this:

[root@te-aai-34-03 plugins]# cat /etc/check_mk/php_fpm_pools.cfg
php_fpm = [
 {"socket": "localhost:9000"}
]
[root@te-aai-34-03 plugins]#

the test according to the checkman works for me.

[root@te-aai-34-03 plugins]# SCRIPT_NAME=/status SCRIPT_FILENAME=/status QUERY_STRING= REQUEST_METHOD=GET cgi-fcgi -bind -connect localhost:9000
