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

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

提示不支持使用proc_opan函数,需要打开

解决方法: vim /usr/local/php/etc/php.ini

查找:proc_open

去掉proc_open函数即可.
