Install a library
luarocks install --local luasec
You can install Lua libraries locally or on a systemwide basis.
A local install indicates that the Lua library you install is available to you,
but no other user of the computer. If you’re developing a Lua application, then
you probably want to install a library to a project directory instead.
In Luarocks terminology, this is a tree.
Your default tree when installing libraries locally is $HOME/.luarocks,
but you can redefine it arbitrarily.
mkdir local
luarocks --tree=./local install cmark
Using a library
You can use the library in your Lua code by defining the package.path variable to point to your local rocks directory
package.path = package.path .. ';local/share/lua/5.3/?.lua'
require("cmark")
If a library you’ve installed is compiled, resulting in a .so file (a .dll on Windows and .dylib on macOS), then you must add to your cpath instead. For instance, the luafilesystem library provides the file lfs.so:
package.cpath = package.cpath .. ';local/share/lua/5.3/?.so'
require("lfs")
