I just follow installation

from allauth.socialaccount.providers.facebook.views import FacebookOAuth2Adapter
from rest_auth.registration.views import SocialLoginView

class FacebookLogin(SocialLoginView):
    adapter_class = FacebookOAuth2Adapter

urlpatterns = [
...
        url(r'^rest-auth/', include('rest_auth.urls')),
    url(r'^rest-auth/registration/', include('rest_auth.registration.urls')),
    url(r'^rest-auth/facebook/$', FacebookLogin.as_view(), name='fb_login'),
