本地安装Python项目后导入本地包出现ModuleNotFoundError

1. 修正导入语句 #

main.py中helpers是YT_Sentiments的子包，当前导入路径无法识别，需改为以下两种方式之一：

• 相对导入（推荐，适配包内结构）：

from .helpers import score
from .helpers import comments

• 绝对导入：

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

2. 简化并修正setup.py配置 #

你的项目采用src布局，原setup.py的package_dir配置错误，且手动指定包名易出错。修改后配置如下：

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={"": "src"},  # 指定所有包的根目录为src
    packages=find_packages(where="src"),  # 自动从src目录扫描所有包
    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",
    ],
    python_requires=">=3.8",
)

注：已移除重复的vaderSentiment依赖项。

3. 重新构建安装 #

执行以下命令清理旧安装包并重新构建安装：

pip uninstall -y YT_Sentiments
python setup.py bdist_wheel sdist
pip install dist/YT_Sentiments-0.0.4-py3-none-any.whl
