I was recently going over the tutorial with someone and started with: 

1. `conda create -n xarray-tutorial xarray` 
running `ds = xr.tutorial.load_dataset(""air_temperature"")` --> `ImportError: using the tutorial data requires pooch`
2. we install pooch and then hit: `ValueError: cannot guess the engine, try passing one explicitly`
3. after consulting the docstring we then try ds = xr.tutorial.load_dataset(""air_temperature"", engine=""netcdf4"") and hit `ValueError: unrecognized engine netcdf4 must be one of: ['store']` 
4. being familiar with xarray we then installed netcdf4 into our environment and all is well.
 
I do think these error messages are not obvious to fix for new xarray users trying out the tutorial (especially # 3 above)

> we could definitely improve the error message, though. Something like ""unknown engine {engine}, please choose one of the installed engines: {engines}"", maybe? 

Yes. Perhaps with a link to docs with a list of engines? for the tutorial case specifically could also update the ImportError message to read `ImportError: please install 'pooch' and 'netcdf4' to use xarray tutorial data`?
