    1. From package manager
      • Scoop: scoop install lua-language-server
      • Homebrew: brew install lua-language-server
      • Macports: sudo port install lua-language-server

Note

If you plan to use a symbolic link to point to the language server, you will want to instead use a wrapper script like the one below. This is required because the language server expects to find files in the current working directory.

Shell
#!/bin/bash
exec "<path-to-directory>/bin/lua-language-server" "$@"
