发表评论时，发现Vercel日志中记录了下面的一段错误日志：

Error: [Ipv4ToRegion] db file not exists : /var/task/node_modules/ip2region/data/ip2region.db

是这个IP数据库没有下载成功，或是要哪里指定IP库的变量吗？

When commenting, I found the following error log recorded in the Vercel log:

Error: [Ipv4ToRegion] db file not exists : /var/task/node_modules/ip2region/data/ip2region.db
    at new Ipv4ToRegion (/var/task/node_modules/ip2region/dist/lib/ipv4.js:25:19)

Is it because the IP database was not downloaded successfully, or where do I need to specify the variables of the IP database?

db 文件是包含在 npm 包里面的，应该没有问题。本地 vercel dev 启动一下试试，如果还不行，就进仓库把 db 文件下载下来放仓库里单独指定环境变量把。

---

The db file is included in the npm package, so there should be no problem. Try starting vercel dev locally. If it still doesn't work, go to the warehouse, download the db file and put it in the warehouse to specify the environment variables separately.

看来是只能手动下载db文件到仓库里，这个db路径的环境变量名称是什么？查看手册只找到 DISABLE_REGION 这个变量参数。

---

It seems that you can only manually download the db file to the warehouse. What is the environment variable name of this db path? Looking at the manual, I only found the variable parameter DISABLE_REGION.
