Ember.js: TypeError: _ember2.default.String is undefined (ember s)

I got this problem when run:

ember s

I don't know what is the origin of the problem. The application are run but the page blank and I got this error cited below on browser console.

My versions:

ember-cli: 2.13.1
http_parser: 2.7.0
node: 4.7.2
v8: 4.5.103.43
uv: 1.9.1
zlib: 1.2.8
ares: 1.10.1-DEV
icu: 57.1
modules: 46
openssl: 1.0.2g
os: linux x64

See the problem at the browser console:
