Resolve Vim's dylib issue with macOS

Perhaps you've been using your macOS setup for a while, and then you try to run Vim after a while. But then, instead of Vim starting up, an error is raised. Here's the error:

dyld: Library not loaded: /usr/local/opt/lua/lib/liblua.5.3.dylib
  Referenced from: /usr/local/bin/vim
  Reason: image not found

So what caused this is that after using brew for a while, an older version of Lua that Vim relies on may have been uninstalled. To be perfectly honest, I have no idea exactly what may have caused this issue. But whatever it is, we need to fix it.

A good fix would be to search for all versions of Lua on homebrew. To do that, invoke the following command:

brew search lua

Which should output something like this:

==> Formulae
lua ✔
lua@5.1
lua@5.3
luabind
luajit
luaradio
luarocks
luaver

Install Lua version 5.3.

brew install lua@5.3

Then run:

brew link --overwrite lua@5.3

If there are other libraries that have been royally screwed up by Homebrew, and that Vim relies on them, then do follow the above pattern for all other libraries.

Good luck!
