Python3 导入错误。以前的办法都解决不了

Question

正在尝试从另一个文件夹导入其他类。一次又一次地出现导入错误...... ImportError：尝试在没有已知父包的情况下进行相对导入我怎样才能摆脱它？我在“模块”文件夹中有 init.py，但这也无济于事......

“模块”文件夹中的代码：

snake.py

import pygame
from pathlib import *
base_directory = Path(__file__).parent.absolute()
object_size = 40  # ! dimension of object image. choose a squire sized image.

class Snake:
 def __init__(self, parent_screen, snake_size):
     self.parent_screen = parent_screen
     self.snake_directory = 'resources/block.jpg'
     self.full_snake_directory = base_directory / self.snake_directory
     self.snake = pygame.image.load(self.full_snake_directory).convert()

     self.direction = 'right'
     self.snake_size = snake_size
     self.snake_x = [object_size]*snake_size
     self.snake_y = [object_size]*snake_size

 def draw_snake(self):
     for size in range(self.snake_size):
         self.parent_screen.blit(self.snake, (self.snake_x[size], self.snake_y[size]))
     pygame.display.flip()

 def move_left(self):
     self.direction = 'left'

 def move_right(self):
     self.direction = 'right'

 def move_up(self):
     self.direction = 'up'

 def move_down(self):
     self.direction = 'down'

 def walk_snake(self):
     for position in range(self.snake_size-1, 0, -1):
         self.snake_x[position] = self.snake_x[position-1]
         self.snake_y[position] = self.snake_y[position-1]

     if self.direction == 'left':
         self.snake_x[0] -= object_size
     elif self.direction == 'right':
         self.snake_x[0] += object_size
     elif self.direction == 'up':
         self.snake_y[0] -= object_size
     elif self.direction == 'down':
         self.snake_y[0] += object_size

     self.draw_snake()

 def increase_snake_size(self):
     self.snake_size += 1
     self.snake_x.append(-1)
     self.snake_y.append(-1)

food.py

import pygame
from pathlib import *
import random

base_directory = Path(__file__).parent.absolute()
object_size = 40  # ! dimension of object image. choose a squire sized image.

class Food:
   def __init__(self, parent_screen):
   self.parent_screen = parent_screen
   self.food_directory = 'resources/apple.jpg'
   self.full_food_directory = base_directory / self.food_directory
   self.food = pygame.image.load(self.full_food_directory).convert()
   self.food_x = object_size * 3
   self.food_y = object_size * 3

def draw_food(self):
   self.parent_screen.blit(self.food, (self.food_x, self.food_y))
   pygame.display.flip()

   self.food_x = random.randint(0, 26) * object_size

而不是写作

from .modules import

尝试

from modules import

同时在主文件夹中添加 __init__.py

Python3 导入错误。以前的办法都解决不了

Python3 ImportError. can't solved by any previous way
