How to fix bad argument #2 error when trying to execute luadist.install(luaposix)?

Question

Lua

I use ZeroBrane Studio IDE
I want to add extensions using LuaDist extension, but I get an error:

luadist.install('luaposix')
Running 'install' for Lua 5.1 in 'C:\Users\aleksandr.vilkov\luadist\5.1'.
C:\Lua\lualibs/dist\depends.lua:56: bad argument #2 to 'insert' (number expected, got nil)
Completed in 0 second(s).

Requires a numeric argument for some reason, however the LuaDist usage examples don't have anything like that.
