你的代码缩进不正确，导致出现了 IndentationError 错误。可以尝试将代码修改为如下所示：

import arcpy

# 输入参数
fc = arcpy.GetParameterAsText(0)  # 要素类
field = arcpy.GetParameterAsText(1)  # 查询字段
value = arcpy.GetParameterAsText(2)  # 查询条件值

# 构建查询语句
query = "{} = '{}'".format(arcpy.AddFieldDelimiters(fc, field), value)

# 删除符合条件的要素
with arcpy.da.UpdateCursor(fc, ["OID@", field], where_clause=query) as cursor:
    for row in cursor:
        cursor.deleteRow()
        arcpy.AddMessage("Deleted OID {} with {} = {}".format(row[0], field, value))

修改后，可以尝试重新运行代码。
