App.service("FreshlyPressed",["$http", "log", FreshlyPressed]);
App.controller("AppCtrl" ,["$scope" , "FreshlyPressed", "$log" , AppCtrl]);
在我看来，您在第一本log中缺少$ 。

It should be $log instead of log in following line- 它应该是$log而不是在以下行中log -
App.service("FreshlyPressed",["$http", "$log", FreshlyPressed]);
Angular injector is not able to find the log module and therefore the logprovider error. 角度注射器无法找到log模块，因此无法找到logprovider错误。 Correct module is $log 正确的模块是$log
