如何从另一个 django 项目执行 django 命令？
How to execute django commands from another django project?
我在同一台服务器上有两个 django 项目。
项目 1：运行正在（使用 gunicorn）接收休息请求和显示数据。
项目2：仅用于执行django命令，不运行ning。
我想 运行 project1 中 project2 的命令，但是当我什么都不做时。
我试过了：
Popen(["/opt/xxx/venv3/bin/python", "/opt/xxx/src/manage.py", "custom_commands", "params"])
os.system("/opt/xxx/venv3/bin/python /opt/xxx/src/manage.py custom_commands params")
没有成功（我试图读取 Popen 的输出，但它是空的）。
当我 运行 在服务器上 python shell 中使用相同的命令时，它可以正常工作，因此它必须与从另一个 django 项目调用 django 命令有关。

我设法用 popen 读取了 stderr，我得到：
Traceback (most recent call last):\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/core/management/__init__.py", line 224, in fetch_command\n app_name = commands[subcommand]\nKeyError: \'mail_lre\'\n\nDuring handling of the above exception, another exception occurred:\n\nTraceback (most recent call last):\n File "/opt/project2/src/manage.py", line 22, in <module>\n main()\n File "/opt/project2/src/manage.py", line 18, in main\n execute_from_command_line(sys.argv)\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line\n utility.execute()\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/core/management/__init__.py", line 395, in execute\n self.fetch_command(subcommand).run_from_argv(self.argv)\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/core/management/__init__.py", line 231, in fetch_command\n settings.INSTALLED_APPS\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/conf/__init__.py", line 82, in __getattr__\n self._setup(name)\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/conf/__init__.py", line 69, in _setup\n self._wrapped = Settings(settings_module)\n File "/opt/project2/venv3/lib/python3.9/site-packages/django/conf/__init__.py", line 170, in __init__\n mod = importlib.import_module(self.SETTINGS_MODULE)\n File "/usr/local/lib/python3.9/importlib/__init__.py", line 127, in import_module\n return _bootstrap._gcd_import(name[level:], package, level)\n File "<frozen importlib._bootstrap>", line 1030, in _gcd_import\n File "<frozen importlib._bootstrap>", line 1007, in _find_and_load\n File "<frozen importlib._bootstrap>", line 972, in _find_and_load_unlocked\n File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed\n File "<frozen importlib._bootstrap>", line 1030, in _gcd_import\n File "<frozen importlib._bootstrap>", line 1007, in _find_and_load\n File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked\n File "<frozen importlib._bootstrap>", line 680, in _load_unlocked\n File "<frozen importlib._bootstrap_external>", line 790, in exec_module\n File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed\n File "/opt/editik/src/Editik_django/__init__.py", line 4, in <module>\n from utils.apps import app_ready\n File "/opt/project2/src/utils/apps.py", line 15, in <module>\n from api.settings import LOG_EDITIK_DIR\n File "/opt/project2/src/api/__init__.py", line 4, in <module>\n from utils.apps import app_ready\nImportError: cannot import name \'app_ready\' from partially initialized module \'utils.apps\' (most likely due to a circular import) (/opt/project2/src/utils/apps.py)
真的很奇怪，因为它在 django 项目之外工作。
好的，我通过在命令末尾添加 --pythonpath 和 --settings 解决了这个问题。
喜欢：
