cannot compute annual mean with xarray 0.14.0 about esmlab

[mnlevy1981]

This looks like a different error than you were previously getting -- didn't you show me

TypeError: Only valid with DatetimeIndex, TimedeltaIndex or PeriodIndex, but got an instance of 'CFTimeIndex'

I got the above error trying to run ds = esmlab.resample(ds, freq='ann').mean('time').compute() in a notebook and @andersy005 said it was related to #139 (I didn't save the traceback from that error, but I can recreate it if that would be helpful)

Anderson fixed this in pydata/xarray#3430. if you install cftime=1.0.3.4 that error should not appear.

@mnlevy1981 , I get the error message that you are showing if I pass decode_times=False to xr_ds_ex, instead of True. So I'm getting different error messages if time is decoded or not.

Thanks @dcherian!
Switching to cftime=1.0.3.4 solves my problem when I pass decode_times=True.
(I might have the meaning of decoded time reversed here compared to xarray. I tend to get confused about which representation of time is viewed as being encoded vs. not.)
