Alternatively, the host program can open them individually by using luaL_requiref to call luaopen_base (for the basic library), luaopen_package (for the package library), luaopen_coroutine (for the coroutine library), luaopen_string (for the string library), luaopen_utf8 (for the UTF-8 library), luaopen_table (for the table library), luaopen_math (for the mathematical library), luaopen_io (for the I/O library), luaopen_os (for the operating system library), and luaopen_debug (for the debug library). These functions are declared in lualib.h.
If package.loaded[modname] is not true, calls the function openf with the string modname as an argument and sets the call result to package.loaded[modname], as if that function has been called through require.
If glb is true, also stores the module into the global modname.
Leaves a copy of the module on the stack.
If we do not want to use libraries like io, os, we can open necessary libraries.
Solution
Now it use luaL_requiref() to open necessary libraries.

Now it use
luaL_requiref()to open necessary libraries.
