LuaJIT + luarocks in macOS with `brew`

Was trying to adapt a plugin for mpv. Which uses lua via luajit under the hood (as can be seen with brew deps mpv --tree). The plugin needed libposix & libsocket lua deps to work.

Installed luarocks with brew, as seems it's the pkg manager for lua. However, luarocks installs lua at version 5.4 . Whilst mpv uses luajit. Which turns out to read packages from lua 5.1 paths.

After trying and trying, luarocks --lua-version 5.1 was installing packages in my home directory, and not in /opt/homebrew/(lib|share)/lua/5.1 where luajit expected them to be.

If installing regularly with luarocks install luaposix, they are installed to /opt/homebrew/(lib|share)/lua/5.4.

Using --global fails 🙃

Using sudo fails

Installing [email protected] and then luarocks doesn't make it work either

So the command you have there is a quirky workaround you can do to install dependencies for a brew installed luajit / [email protected] when using luarocks from brew.

Weird, but works
