GloVe has been unmaintained and broken for a long time. The only people asking about it where those who were stumped by the broken example.
GloVe on its own has one intrinsic problem: a vocabulary of size N requires to build a matrix of NxN. This resulted in suboptimal performance for most people.
Overall, there are better performing approaches these days so it isn't worth the effort to fix this implementation.
