1702025553 I_kwDOAMm_X85lctlR 7831 Can't open datasets with the `rasterio` engine. simonrp84 13449576 open 0     7 2023-05-09T13:20:05Z 2023-06-21T19:39:46Z   NONE      

What happened?

Hello, When using this command: data = xr.open_dataset(my_filename, engine="rasterio")

I get an error: ValueError: unrecognized engine rasterio must be one of: ['netcdf4', 'scipy', 'store', 'zarr']

This error is generated because I don't have rioxarray installed. However, that's not clear from the message and the user is likely to assume that it's because they don't have rasterio installed. Would it be possible to improve this error message to allow the user to see that they require rioxarray?

What did you expect to happen?

An error message to be displayed that helps the user understand which package is missing. Something like: ValueError: unrecognized engine rasterio must be one of: [engines]. The rasterio engine requires rioxarray to be installed.

Minimal Complete Verifiable Example

```Python To make a new conda env:

conda create --name xrtesting conda activate xrtesting conda install xarray rasterio Then, to generate the error: import xarray as xr my_filename = 'test.tif' # This triggers the error even if the file is not present data = xr.open_dataset(my_filename, engine="rasterio")

MVCE confirmation

  • [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
  • [X] Complete example — the example is self-contained, including all data and the text of any traceback.
  • [X] Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
  • [X] New issue — a search of GitHub Issues suggests this is not a duplicate.
