setuptools：从zip中删除lib/python3.5/site-packages前缀

Question

我试图创建一个应该作为zip文件分发的包，只包含包本身。不幸的是，至少从virtualenv运行时，zip包含很长的子目录。以下是项目的文件结构：

.
├── my_package
│   └── __init__.py
├── README.md
└── setup.py

在设置.py包含：

^{pr2}$

当我运行python setup.py bdist_dumb --format zip --relative时，我得到以下输出：

如您所见，它将包放入lib/python3.5/site-packages，这是我不想要的。我只希望这个包包含my_package/*。在

如果我们能阻止my_package*.egg-info/*被打包，那就更好了，但是我的首要问题是如何去掉lib/python3.5/site-packages前缀。在

这似乎提供了我想要的行为。但是，如果有一个更优雅的解决方案，例如通过向setup()传递某些参数，我很乐意听到这个消息。在

from setuptools import setup, find_packages
from setuptools.command.install import install


class CustomInstall(install):
    """Ensures the module is placed at the root of the zip file."""

    def initialize_options(self):
        super().initialize_options()
        self.prefix = ''
        self.install_lib = ''

setup(
    cmdclass={'install': CustomInstall},
    name='my_package',
    version='1.0.0',
    author='my name',
    author_email='my-email@example.com',
    packages=find_packages('.'),
    data_files=[('my_package', ['README.md'])],
    zip_safe=True,
)
