Cannot install "class"

[LivelyCarpet87]

I cannot install prerequisite class via luarocks. I get the following errors: luarocks install class Installing https://raw.githubusercontent.com/torch/rocks/master/class-scm-1.rockspec... Using https://raw.githubusercontent.com/torch/rocks/master/class-scm-1.rockspec... switching to 'build' mode

Missing dependencies for class: argcheck >= 1

Using https://raw.githubusercontent.com/torch/rocks/master/argcheck-scm-1.rockspec... switching to 'build' mode Cloning into 'argcheck'... fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

I haven't followed the latest update/version of Lua. If you have troubles, I recommend that you use our latest PyTorch version in Python.
