Our crystal ball is in repair for the moment.
Could you specify which module (and version) you are trying to install?
Probably the install instruction or readme file will specify another prerequisite module, Frameworks or editors.
NB: This kind of situations come over and over. There should be a better error handling in the module administration and loading part, because now the script dies simply without any message, no matter if debug is on or off. If one module fails, the others should remain visible and installable.
