如何修复“错误：生成错误：无法安装cjson.dll”

Question

我想安装lua-cjson，运行luarocks install lua-cjson

时出现此错误

Error: Build error: Failed installing cjson.dll

我的cl版本是https://imgur.com/a/YiSVqTm

我的羽绒服版本是：

luarocks 2.0.2
LuaRocks main command-line interface

我不知道该如何解决

这是我在VS 2019（2）的Developer Command Prompt中运行luarocks install lua-cjson时的输出：
