PIP不会将data_files安装到正确的位置

时间：2018-04-18 15:23:34

标签： python pip setuptools distutils setup.py

我想在Pypi上传我的包，并通过PIP提供。我的软件包需要在/etc/和/usr/下安装文件（conf文件和数据文件）。

为了实现这一目标，我使用data_files中的setup()属性。

当我通过python setup.py install运行安装时，一切正常，我的文件安装在我想要的地方。

但是当我使用PIP时，我的文件似乎被卡在/usr/local/lib/python2.7/dist-packages下，我不明白为什么。使用PIP时如何正确安装文件？

我的软件包是一个网络工具，默认情况下我需要在/etc/network/下安装文件，所以我不希望用户除了pip install my_package

之外还要做其他事情。

ENV：

$ pip -V
pip 10.0.0 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
$ cat /etc/os-release
NAME="Ubuntu"
VERSION="16.04.3 LTS (Xenial Xerus)"
ID=ubuntu

我已将问题简化为一个非常简单的setup.py文件。

$ tree
.
├── my_package
│   ├── __init__.py
│   ├── my_package.conf
│   ├── my_package.py
│   └── test_file
└── setup.py

1 directory, 5 files

distutils和setuptools都出现了问题

$ cat setup.py
#!/usr/bin/env python

from distutils.core import setup
#from setuptools import setup

setup(
    name='my_package',
    version='1.0',
    description='Test package',
    author='Julien',
    author_email='julien@website.com',
    packages=['my_package'],
    data_files=[
        ('/tmp/', ['my_package/test_file']),
        ('/etc/my_package/', ['my_package/my_package.conf']),
        ('/usr/bin/', ['my_package/my_package.py'])
    ]
)

以下是一些日志（首先通过python setup.py install然后通过pip安装并轻松安装）：

看到它效果很好，现在如果我清理它并再次尝试使用pip：

error: Setup script exited with error: SandboxViolation: open('/tmp/test_file', 'wb') {}

The package setup script has attempted to modify files on your system
that are not within the EasyInstall build area, and has been aborted.

This package cannot be safely installed by EasyInstall, and may not
support alternate installation locations even if you run its setup
script by hand.  Please inform the package's author and the EasyInstall
maintainers to find out if a fix or workaround is available.

我真的被困在这里，如果有人能帮助我解决这个问题，我将非常感激！ :)

谢谢！
