本地安装Python项目后导入本地包时出现ModuleNotFound错误

Question

我正在打包我的第一个Python项目，我有两个带有辅助函数的文件，comments.py和score.py存储在子目录中。

YT_Sentiments/
└── src/
    ├── YT_Sentiments/
    │   ├── helpers/
    │   │   ├── __init__.py
    │   │   ├── score.py
    │   │   └── comments.py
    │   ├── __init__.py
    │   └── main.py
    ├── LICENSE
    ├── pyproject.toml
    ├── README.md
    └── setup.py

在我的 main.py 中导入两个文件

    from helpers import score
    from helpers import comments

当我在本地构建并安装它时，出现错误：

    File "C:\Users\AppData\Local\Programs\Python\Python311\Lib\site-packages\YT_Sentiments\main.py", line  
    1, in <module>
    from helpers import score
    ModuleNotFoundError: No module named 'helpers'

我已经遵循了至少 4 个有关打包的教程，并实现了我认为可以解决我的问题的内容（setup.py 和 pyproject.toml）

设置.py

    from setuptools import find_packages, setup

    with open("README.md") as f:
        long_description = f.read()

    setup(name = "YT_Sentiments",
          version = "0.0.4",
          description = "analyze comments from any youtube video!",
          package_dir = {"YT_Sentiments":"YT_Sentiments",
                     "YT_Sentiments.helpers":"YT_Sentiments/helpers",},
          packages = ['YT_Sentiments', 'YT_Sentiments.helpers'],
          long_description=long_description,
          long_description_content_type="text/markdown",
          license = "MIT",
          classifiers=[
                       "Programming Language :: Python",
                       "Topic :: Software Development :: Libraries :: Python Modules",
                       "Operating System :: OS Independent",
                       ],
          install_requires = ["emoji>=2.12.1",
                              "google_api_python_client>=2.139.0",
                              "vaderSentiment>=3.3.2",
                              "vaderSentiment>=3.3.2",],
          python_requires = ">=3.8",  
        )

pyproject.toml

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

[project]
name = "YT_Sentiments"
version = "0.0.4"
description = "A python package that allows you to perform sentiment analysis on Youtube comments"
readme = "README.md"
requires-python = ">=3.8"
classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",
]

dependencies = [
  "emoji>=2.12.1",
  "google_api_python_client>=2.139.0",
  "vaderSentiment>=3.3.2",
  "vaderSentiment>=3.3.2",
]
[project.urls]
Homepage = "https://github.com/pypa/sampleproject"
Issues = "https://github.com/pypa/sampleproject/issues"`

我认为这个问题的原因是你的终端不在主文件夹中。你能试试这个吗？

from src.YT_Sentiments.helpers import score
from src.YT_Sentiments.helpers import comments
