Not sure when you used Lua but there is a package manager called LuaRocks now which has some pretty nice packages in it for many purposes. I don't think it'd be too hard to get Lua running inside of a Python env either :)
I use lua a lot and like it fine but the build/dependency/tooling situation is a fucking mess. It exposes you to a lot of the inconvenience of C in the end.
The Lua libraries in these areas are very well maintained.
That said 90% of the time libraries ship as a single lua file and it’s often better to copy and paste it into your project. I have a modified version of lume I like to use floating around :)
This spartan approach to libraries is a strength of Lua.
