在 Windows 10 下的 OpenResty ，报错：module ‘lib.redis’ not found: no field package.preload[‘lib.redis’]
1、运行 lua 程序，报错：500 Internal Server Error openresty/1.19.9.1。如图1

2、查看 Nginx 日志文件，morefunresty.dev.chinamcloud.cn.error.log，module ‘lib.redis’ not found: no field package.preload[‘lib.redis’]。如图2

3、编辑 Nginx 文件，添加 lua_package_path，以配置 openresty 的文件寻址路径
# 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、重启 Nginx 服务器后，仍然报同样的错误。查看 Nginx 日志，新增一行：no file ‘E:/wwwroot/msi_main/resty/app/common/lib/lib\redis.lua’，确认 ?.lua 被替换为：lib\redis.lua，自动增加了一级目录：/lib
2021/09/22 18:47:41 [error] 42716#42404: *304 lua entry thread aborted: runtime error: E:/wwwroot/msi_main/resty/app/mods/draw/prizes.lua:10: module 'lib.redis' not found: no field package.preload['lib.redis'] no file 'E:/wwwroot/msi_main/resty/app/common/lib/lib\redis.lua' no file './site/lualib/lib\redis.ljbc' no file './site/lualib/lib\redis/init.ljbc' no file './lualib/lib\redis.ljbc' no file './lualib/lib\redis/init.ljbc' no file './site/lualib/lib\redis.lua' no file './site/lualib/lib\redis/init.lua' no file './lualib/lib\redis.lua' no file './lualib/lib\redis/init.lua' no file '.\lib\redis.lua' no file 'C:\openresty-1.19.9.1-win64\lualib\lib\redis.lua' no file 'C:\openresty-1.19.9.1-win64\lua\lib\redis.lua' no file 'C:\openresty-1.19.9.1-win64\lua\lib\redis\init.lua' no file './site/lualib/lib\redis.so' no file './lualib/lib\redis.so' no file '.\lib\redis.dll' no file 'C:\openresty-1.19.9.1-win64\lualib\lib\redis.so' no file 'C:\openresty-1.19.9.1-win64\lib\redis.dll' no file 'C:\openresty-1.19.9.1-win64\loadall.dll' no file './site/lualib/lib.so' no file './lualib/lib.so' no file '.\lib.dll' no file 'C:\openresty-1.19.9.1-win64\lualib\lib.so' no file 'C:\openresty-1.19.9.1-win64\lib.dll' no file 'C:\openresty-1.19.9.1-win64\loadall.dll' stack traceback: coroutine 0: [C]: in function 'require' E:/wwwroot/msi_main/resty/app/mods/draw/prizes.lua:10: in main chunk, client: 127.0.0.1, server: morefunresty.dev.chinamcloud.cn, request: "GET /lua/api/draw/prizes?act_id=a0535444-283c-481e-9bcd-b0673a28f3ca HTTP/1.1", host: "morefunresty.dev.chinamcloud.cn"
5、编辑 Nginx 文件，添加 lua_package_path，以配置 openresty 的文件寻址路径，删除：/lib
# set search paths for pure Lua external libraries (';;' is the default path):
lua_package_path 'E:/wwwroot/msi_main/resty/app/common/?.lua;;';
server {
}
6、运行 lua 程序，不再报错。如图3
