我刚刚用 setuptool 制作了一个 Python 包，但是我遇到了一个问题，如果我从 Ubuntu 存储库中预安装所有东西，它的工作，但是当我使用 PyPi 时，安装失败，因为在 PyPi 上只包含源并且它必须是编译，所以安装过程中有很多错误源。在安装包期间如何安装 Ubuntu 包？我的想法是subprocess，有没有更好的方法？

从 apt 存储库安装下载的二进制文件已经使用所需的系统库构建。如果没有，apt 管理器会确保所有系统库也已安装。使用 setuptools（pip 或 easy_install）安装仅获取python要求；而不是构建/系统要求。

在您的情况下，错误是error: X11 libraries not found. 这意味着 X11 的构建标头在您的系统中不可用。解决这个问题的一个简单方法是告诉 apt 只下载和安装你的包的依赖项（而不是包本身）。这将确保当您使用 pip 或 easy_install 时，Python 会找到它需要的一切。

例如，psycopg2是 Postgresql 的 Python 库。要构建它，您需要 postgresql 支持库（头文件和文件）。这些在 PyPi 中不可用。debian 软件包python-psycopg2将正确安装所有外部要求。现在，如果我想在虚拟环境中安装 psycopg2，我首先需要确保我的系统具有构建包的所有外部要求，因此我运行以下命令：

sudo apt-get build-dep python-pyscopg2

这只会安装依赖项（所有支持的标头），以便我以后可以手动安装它。

在您的情况下，您应该运行apt-get build-dep python-enable，它将获取所需的所有内容：

# apt-get build-dep python-enable

Need to get 35.5 MB of archives.
After this operation, 97.3 MB of additional disk space will be used.

一旦安装了所有这些库，您的 pypi 包将正确安装。

PyPi 仅适用于 Python 包（以及这些包的特定于 Python 的依赖项）。对于任何外部要求；您需要在安装文档中指定它们或让它们在系统上可用，以便安装过程能够成功。

Try using this modified script:

from setuptools import setup

setup( 
    name = 'SomeName',
    version = '0.1',
    packages=find_packages(),
    author = 'Some Author',
    maintainer = 'Some',
    maintainer_email = 'some@email.com',
    description = '',
    url = 'www.some.com',
    install_requires = ['envisage',
                        'pyface',
                        'apptools',
                        'chaco',
                        'traits',
                        'traitsui',
                        'mysql-connector-python',
                        'pysnmp4',
                        'pyasn1',
                        'm2crypto',
                        'netifaces'

                        ],
