使用 react-pdf，其中 pdfjs 需要设置 pdfjs.GlobalWorkerOptions.workerSrc，鉴于一些众所周知的原因，所以直接去 node_modules 把 pdf.worker.min.mjs 放到public目录，锁死包版本，不要折腾别的了。
nginx 服务器需要修改对mjs的支持

# `nginx` 路径根据需要调整
vim /etc/nginx/mime.types
# 在下面这一行的 `js` 后面加上 `mjs`
application/javascript                 js;
# 如
application/javascript                 js mjs;
# 保存并退出
:wq
# 重启nginx
nginx -s reload
