cpanel - 用不同的版本的php命令 - /opt/cpanel/ea-php72/root/usr/bin/php - An exception was raised while creating "Request"

现象：在cPanel环境中执行magento2的命令，如 php bin/magento cache:flush提示出错：

An exception was raised while creating "Request"; no instance returned

尝试：用正确的php版本路径再次执行，如 /opt/cpanel/ea-php72/root/usr/bin/php bin/magento cache:flush
