tester@0.0.0 start /home/leanvitale/Documents/Angular 2/Practicas/tester
enter code hereng serve

Environment configuration does not contain "environmentSource" entry.

A new environmentSource entry replaces the previous source entry inside environments.

To migrate angular-cli.json follow the example below:

Before:

"environments": {
  "source": "environments/environment.ts",
  "dev": "environments/environment.ts",
  "prod": "environments/environment.prod.ts"
}


After:

"environmentSource": "environments/environment.ts",
"environments": {
  "dev": "environments/environment.ts",
  "prod": "environments/environment.prod.ts"
}

Yesterday I followed a tutorial to work with Angular 4 and Firebase, I did the dependency updates and noticing that there was little documentation to work I decided to start with Angular 2 and Firebase. The problem is that I was lio with the versions of node and npm, disinfect and install everything and I'm all wrong, now I can not run a default program in Angular 2, I would like if someone can guide me in the uninstallation and installation of everything What it takes to be able to do a project in Angular 2 and Firebase.

Someone to guide me? Thanks!!
