removeLayer() error

ZacharyStanley — Thu, 22 Dec 2022 21:30:29 GMT

Hello-

I'm simply trying to remove a layer from an aprx using arcpy and am getting an error related to the save() function. Below is code and resulting error:

# import modules import arcpy from arcpy import mp import os # remove temporary layers from the map aprx = mp.ArcGISProject(r"N:\Projects\ElectionsOffice\VoterAddresses\VoterAddresses.aprx") aprxMap = aprx.listMaps()[0] for lyr in aprxMap.listLayers(): if lyr.name == 'sgmj_2872_Layer2': aprxMap.removeLayer(lyr) aprx.save()

OSError                                   Traceback (most recent call last)
In  [40]:
Line 7:     aprx.save()

File C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\_mp.py, in save:
Line 308:   return convertArcObjectToPythonObject(self._arc_object.save(*gp_fixargs((), True)))

OSError: N:\Projects\ElectionsOffice\VoterAddresses\VoterAddresses.aprx

I would throw in a print statement or two since I suspect you have no aprxMap or perhaps layers to process.

If all seems fine try a saveAs instead of save, using a different output name to ensure that the process can complete with some form of "save" option

Maybe you (or somebody else) has the project open in ArcGIS Pro?
