python - 为 Django 项目设置 PYTHONPATH 的正确方法

Question

在我的文件 django app tests.py 中，我导入了另一个我创建的名为 helpers 的模块。 helpers 与 tests.py 处于同一目录级别。当我运行 ./manage.py tests 我得到这个错误:

$ ./manage.py test
Creating test database for alias 'default'...
E

ERROR: api.tests (unittest.loader.ModuleImportFailure)

  File "/Users/bli1/Development/projects/cherngloong/cherngloong/api/tests.py", line 8, in <module>
    from helpers.APIHelpers import KeyGrabber
ImportError: No module named 'helpers'

这是我的项目结构:

基本上，tests.py 找不到helpers 模块。我不确定在 django 项目中避免此问题的最佳/正确/标准方法是什么

试试这个:

api.helpers.APIHelpers import KeyGrabber

在 Django 中，包通常以应用名称开头。你也可以试试 relative imports .
