Missing expected target path results.

Hi @YoulongYan,

Thanks for posting and providing the log file. Do you think you could download and try the latest version of InVEST [https://naturalcapitalproject.stanford.edu/software/invest](https://naturalcapitalproject.stanford.edu/software/invest).

Looking at your logfile it also appears that you input `ws.shx` for your watershed path. Could you input the Shapefile instead, it should be `ws.shp`.

Let us know if these two things help and if not we continue to help you debug.

Doug
