The Process class relies on proc_open, which is not available on your PHP installation.

安装 Swoft 

composer create-project swoft/swoft swoft

出现如下报错

The Process class relies on proc_open, which is not available on your PHP installation.

在 php.ini 中，找到 disable_functions 选项，proc_open，同时该框架依赖 proc_get_status 也一同删掉

OK
