nginx on windows prompts no input file specified, I followed the configuration online?

<code>server {
        listen       80;
        server_name  m.test.com;

        
        ## Root and index files.
        root html/test;
        index  index.php index.html index.htm;

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

         location / {
            # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
            #
            location ~ \.php$ {
                root           html;
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
                include        fastcgi_params;
            }
         }

It may be this problem: root html
You may need to write it completely: root /html

On Windows, it is best to use an absolute address for your root, such as D:/www
