这个错误是因为你尝试删除了必须的字段 SHAPE。在 ArcGIS 中，如果要删除要素类或表的所有字段，必须首先删除 SHAPE 字段，然后删除其他字段。您可以修改代码以先删除 SHAPE 字段，再删除其他字段，如下所示：

# Import arcpy module
import arcpy

# Define the input feature class or table
fc = arcpy.GetParameterAsText(0)

# Get a list of all fields in the input feature class or table
fields = arcpy.ListFields(fc)

# Loop through each field and delete it (except for OBJECTID and SHAPE)
for field in fields:
    if field.name != "OBJECTID" and field.name != "SHAPE":
        arcpy.DeleteField_management(fc, field.name)

# Print a message to indicate that the fields have been deleted
arcpy.AddMessage("All non-required fields have been deleted from " + fc)

在这个修改后的代码中，我们添加了一个条件来检查字段名是否为 OBJECTID 或 SHAPE，如果不是，则删除该字段。现在，您应该能够成功地删除要素类或表的所有非必需字段。
