构建python包找不到requirements.txt

Question

这是我第一次必须在我实际工作的仓库中使用旧 git 存储库的内容。我决定尝试创建一个 Python 包，将其作为库导入到新版本中（我使用的是 gitlab）。

\n

我已经搜索了相关信息来做到这一点，但很难找到一致的解决方案。

\n

我首先尝试通过执行以下命令在本地构建包：

\n

python setup.py bdist_wheel

\n

进而：

\n

python3 -m build

\n

该包应该构建wheel的依赖关系，但在尝试查找requirements.txt文件时它崩溃了。

\n

我之前看到该命令写入 Egg-info 文件，创建包，并将文件从本地复制到包：

项目结构是：

\n

机械化号码包

\n

\n

自述文件\nrequirements.txt\nutils\nconfig\nmodels\nmain.py

\n

\n

setup.py 文件：

\n

import setuptools\n\nwith open("README.md", "r") as fh:\n    long_description = fh.read()\n\nwith open("requirements.txt", "r") as fh:\n    install_requires = fh.read()\n\nsetuptools.setup(\n    name="acivit.mechanized_number_recognition",\n    version="0.0.3",\n    author="Acivit",\n    description="`System to detect the Mechanized Number",\n    long_description=long_description,\n    long_description_content_type="text/markdown",\n    url="https://gitlab.com/acivit/project/ai_systems/mechanized-number-recognition",\n    # \xc2\xa0Disable zip_safe to allow compatibility with mypy.\n    # See: https://mypy.readthedocs.io/en/stable/installed_packages.html#making-pep-561-compatible-packages\n    zip_safe=False,\n    package_data={"mechanized_number_recognition": ["py.typed"]},\n    packages=setuptools.find_packages(),\n    classifiers=[\n        "Programming Language :: Python :: 3",\n        "Operating System :: OS Independent",\n    ],\n    python_requires=">=3.6",\n    install_requires=install_requires,\n)\n\n\n

知道为什么会发生这种情况吗？或者还有其他方法来构建包？

大胆猜测您的..MANIFEST.in中没有requirements.txt include，如下所示：

include *.md LICENSE requirements.txt CHANGELOG
