If there is a posix path like /a/b//c, the regex pattern to find root directory won't match anything and cause server crashing even if the path is valid. I think windows path also has this problem.

This will happen if someone add an environment path end with a separator.

export PATH="$PATH:/path/to/lua-language-server/bin/"

This environment path will be used to extend to package.cpath. So, package.cpath here is /path/to/lua-language-server/bin//?.so which the current regex pattern can't recognize.
