Django: ModuleNotFoundError: No module named ‘***‘

環境：

• python 3.8.10
• Django 3.2.5

項目目錄結構：

PrjRoot

|my_project

|— __init__.py

|— 其它

|my_app

|— __init__.py

|— my_util.py

|— 其它

其中

my_util.py

是我自己寫的工具類,在views.py中導入，在用指令行啟動時抛出如下錯誤：

File "<frozen importlib._bootstrap>", line 1014, in _gcd_import
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 671, in _load_unlocked
  File "<frozen importlib._bootstrap_external>", line 848, in exec_module
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "/Users/hq/PycharmProjects/django_learn/path_test/urls.py", line 2, in <module>
    from . import views
  File "/Users/hq/PycharmProjects/django_learn/path_test/views.py", line 2, in <module>
    import my_util
ModuleNotFoundError: No module named 'my_util'
           

解決方法：

在

my_app/__init__.py

中加入下面的代碼

import sys

sys.path.append(__path__[0])
