ExecuteError:错误000561:所选层的关系无效。无法执行（SelectLayerByLocation）

Question

我正在编写一个代码，在我的nhlroster.shp功能类中，nhl球员只需要打这三个位置中的一个：leftFeild、rightFeild、Center，所有球员都必须出生在瑞典。我的arcpy.SelectLayerByLocation\u管理：运行时错误：对象：执行工具中的错误

import arcpy

arcpy.env.workspace = "C:/Users/jessi/Desktop/CPSUGeog485/project3_2021"
cntryFc = "Countries_WGS84.shp"
leftFeild = "LW"
rightFeild = "RW"
Center = "C"
cntryFeild = "CNTRY_name"
cntry = "Sweden"

#Select only players from target country
whereClause = cntryFeild + " =  '" + cntry + "'"
cntryLayer = arcpy.SelectLayerByAttribute_management(cntryFc, "NEW_SELECTION", whereClause)

#Create Loop for Target Positions
positionList = (leftFeild, rightFeild, Center) 
for plyrPositions in positionList:
    playerQuery = "plyrPosition = '" + plyrPositions + "'"
#Narrow down players born in sweden who play target positions
plyrLayer = arcpy.SelectLayerByLocation_management(cntryLayer, "Contains", positionList)

您需要使用arcpy.MakeFeatureLayer_management（）将shapefile设置为要素层，如按位置选择https://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/select-layer-by-location.htm和按属性选择文档https://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/select-layer-by-attribute.htm的用法文档中所述；在“按属性选择”行中，“新选择”应为“新选择”
