angular js unknown provider error angular-animate

Just to highlight what Olivier said in a comment, make sure you keep your version of angular and angular-animate in sync.

From bower.json

Good

  "dependencies": {
    "angular": "~1.4.6",
    "angular-animate": "~1.4.6",

Bad – out of sync

  "dependencies": {
    "angular": "~1.4.0",
    "angular-animate": "~1.4.6",
