nginx - nginx中的brotli配置问题

Question

我正在关注本指南https://www.vultr.com/docs/add-brotli-support-to-nginx-on-ubuntu-18-04

我已经完成了每一步，但我被困在第 4 步——配置 Nginx

当我添加到nginx.conf

load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;

运行后出现此错误sudo nginx -t：

nginx: [emerg] dlopen() "/usr/share/nginx/modules/ngx_http_brotli_filter_module.so" failed (/usr/share/nginx/modules/ngx_http_brotli_filter_module.so: cannot open shared object file: No such file or directory) in /etc/nginx/nginx.conf:6
nginx: configuration file /etc/nginx/nginx.conf test failed

什么可能导致这种情况？谢谢！
