解决python manage.py shell ModuleNotFoundError: No module named xxx

报错如下：

python manage.py shellTraceback (most recent call last):File "/Users/z/Documents/project/c/manage.py", line 10, in <module>execute_from_command_line(sys.argv)File "/Users/z/.virtualenvs/c/lib/python3.12/site-packages/django/core/management/__init__.py", line 442, in execute_from_command_lineutility.execute()File "/Users/z/.virtualenvs/c/lib/python3.12/site-packages/django/core/management/__init__.py", line 416, in executedjango.setup()File "/Users/z/.virtualenvs/c/lib/python3.12/site-packages/django/__init__.py", line 24, in setupapps.populate(settings.INSTALLED_APPS)File "/Users/z/.virtualenvs/c/lib/python3.12/site-packages/django/apps/registry.py", line 91, in populateapp_config = AppConfig.create(entry)^^^^^^^^^^^^^^^^^^^^^^^File "/Users/z/.virtualenvs/c/lib/python3.12/site-packages/django/apps/config.py", line 193, in createimport_module(entry)File "/opt/homebrew/Cellar/python@3.12/3.12.3/Frameworks/Python.framework/Versions/3.12/lib/python3.12/importlib/__init__.py", line 90, in import_modulereturn _bootstrap._gcd_import(name[level:], package, level)^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^File "<frozen importlib._bootstrap>", line 1387, in _gcd_importFile "<frozen importlib._bootstrap>", line 1360, in _find_and_loadFile "<frozen importlib._bootstrap>", line 1324, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'xxx'

原因 是 manage.py文件里的内容没有导入项目的路径到环境变量里，正确的内容如下：

import os
import sysif __name__ == "__main__":app_path = os.path.dirname(sys.path[0])sys.path.append(app_path)os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxx.settings")from django.core.management import execute_from_command_lineexecute_from_command_line(sys.argv)
