How can I display error messages in a readable way in the Javascript Console?

I am currently working with Angular JS, and sometimes I get some error messages in the console with content like that :

angular.js:15697  **Error: [$injector:unpr] http://errors.angularjs.org/1.8.2/$injector/unpr?p0=eProvider%20%3C-%20e%20%3C-%20AppyController**
    at angular.js:99:1
    at angular.js:4991:19
    at Object.d [as get] (angular.js:5151:32)
    at angular.js:4996:28
    at d (angular.js:5151:32)
    at e (angular.js:5176:58)
    at Object.invoke (angular.js:5200:18)
    at S.instance (angular.js:11814:24)
    at p (angular.js:10627:33)
    at g (angular.js:9942:13)

Do you know how can I simply display those messages in a human-readable way ?

Thanks in advance,

I try a tutorial where I dragged a file named angular.js or angular.min.js, in the main directory,
but it still did not work …
