laravel新建应用报错：The Process class relies on proc_open, which is not

#laravel new blog

Crafting application...

[Symfony\Component\Process\Exception\RuntimeException]

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

解决方法：

打开php.ini，并搜索disable_functions指令，找到类似如下内容：

disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server

找到proc_open并删除即可。
