Python 分包 - 绝对导入失败

Question

This question has been asked in different contexts, but I still am unable to get a successful absolute import.

I have this directory structure

21:48:07$ tree
start_dir
└── top_package
    ├── README.md
    ├── __init__.py
    ├── __pycache__
    │   ├── __init__.cpython-37.pyc
    │   └── secrets.cpython-37.pyc
    ├── subpackage1
    │   ├── __init__.py
    │   └── test.py
    ├── requirements.txt
    ├── secrets.py
    └── subpackage2
        └── __init__.py
  

All I want to be able to do is from test.py be able to import from secrets. Here is the contents of test.py:

# import top_package # ImportError: No module named top_package
# from top_package import secrets # ImportError: No module named top_package

import top_package.secrets # ImportError: No module named top_package

None of these have worked. I've read through multiple pages on having multiple subpackages in a top level package but still no dice.

Is this simply because I'm trying to execute the file directly by running python test.py instead of calling this from start_dir? If so, what's the best way to develop and work around this?

Goal: I want to be able to absolute import secrets from test.py . If possible, I do not want to do anything with the site-packages or with the setup.py . I want to be able to run python test.py and have the line: import top_package not give a ImportError no module found . Please advise the best course of action.

Answer 1

So you created top_package and want to import it anywhere within your system. You can do so by copying the package folder to the site-packages folder of your environment. This is a path where python would look while importing packages.
