It turns out the problem is the babel-core version, after I set it to ^6.3.21, the error disappered.

[zaaack]

@vinz243 It tooks me a lot of time too because there were not much information in google, you are welcome :-)

[morenoh149]

this is odd. You had to roll back to a previous version?

I imagine it installed a newer, non-broken version.
