1. Run the lua program, and it throws an error: 500 Internal Server Error openresty/1.19.9.1. As shown in Figure 1
2. Check the Nginx log file, morefunresty.dev.chinamcloud.cn.error.log, module ‘lib.redis’ not found: no field package.preload[‘lib.redis’]. As shown in Figure 2

3. Edit the Nginx file to add lua_package_path to configure the file search path for openresty
Nginx
# set search paths for pure Lua external libraries (';;' is the default path):
lua_package_path 'E:/wwwroot/msi_main/resty/app/common/lib/?.lua;;';
server {
}
4. After restarting the Nginx server, the same error still occurs. Checking the Nginx log reveals a new line: no file ‘E:/wwwroot/msi_main/resty/app/common/lib/lib\redis.lua’, confirming that ?.lua was replaced with lib\redis.lua, automatically adding an extra directory level: /lib

5. Edit the Nginx file to add lua_package_path to configure the file search path for openresty, and remove: /lib
Nginx
# set search paths for pure Lua external libraries (';;' is the default path):
lua_package_path 'E:/wwwroot/msi_main/resty/app/common/?.lua;;';

6. Run the lua program, and it no longer throws an error. As shown in Figure 3
