luarocks usage

[Rehab]

Hello everyone,

This is my first time to use torch. I downloaded some example and try to execute then on server ( I''m Not administrator. I'm a regular user)

 In these examples they ask to  perform some luarocks installations same as : by

luarocks install cunn

By using this command it gives me access denied.

By using  luarocks install --local cunn   ,It gives me error.

How can I solve this problem?

Thanks

Rehab
