Nginx http basic not working

Hi

I’ve a droplet with Nginx installed, but I can get the http basic working - I followed this tutorial

https://www.digitalocean.com/community/tutorials/how-to-set-up-basic-http-authentication-with-nginx-on-centos-7

And here is the Nginx config

        location /test {
                auth_basic "Restricted";
                auth_basic_user_file /etc/nginx/htpasswd/.test.com;
        }

I went to the /test and it return 404

I suspect the official nginx doesn’t come with http basic module, here is the output of

test@v1 /etc/nginx $ nginx -V

test@v1 /etc/nginx $

The nginx doesn’t have ngx_http_auth_basic_module compiled as indicated by

http://nginx.org/en/docs/http/ngx_http_auth_basic_module.html

However this is the official nginx, can you help me to get http basic auth working?
