Python setuptools install 没有安装包

Question

我从这个 git 仓库创建了一个分支:https://github.com/QQuick/Opy

我在 opy 目录/包中添加了一个 __init__.py。当我运行 setup.py install 时，opy 包没有安装到我的 site-packages 目录中。为什么？

这是 setup.py 脚本:

import os
import sys

sys.path.append ('opy')
import opy

from setuptools import setup
import codecs

def read (*paths):
    with codecs.open (os.path.join (*paths), 'r', encoding = 'utf-8') as aFile:
        return aFile.read()

setup (
    name = 'Opy',
    version = opy.programVersion,
    description = 'OPY - Obfuscator for Python, string obfuscation added, keyword added',
    long_description = (
        read ('README.rst') + '\n\n' +
        read ('license_reference.txt')
    ),
    keywords = ['opy', 'obfuscator', 'obfuscation', 'obfuscate', 'kivy', 'pyo', 'python'],
    url = 'https://github.com/JdeH/Opy/',
    license = 'Apache 2',
    author = 'Jacques de Hooge',
    author_email = 'jacques.de.hooge@qquick.org',
    packages = ['opy'], 
    include_package_data = True,
    install_requires = [],
    classifiers = [
        'Development Status :: 5 - Production/Stable',
        'Intended Audience :: Developers',
        'Natural Language :: English',
        'License :: Other/Proprietary License',
        'Topic :: Software Development :: Libraries :: Python Modules',
        'Operating System :: OS Independent',
        'Programming Language :: Python :: 2.7',
        'Programming Language :: Python :: 3',
    ],
)

总结评论中的陈述:

setuptools.setup 完成它的工作；然而，不是仅仅将模块复制到 site-packages(distutils 所做的)，python setup.py install 将构建一个 egg 文件，它是然后只需将其复制到 site-packages 即可安装。这样，之后只需删除一个 egg 文件即可轻松卸载软件包。

如果您不喜欢将包安装在存档中，您可以:

• 执行“旧的且难以管理的”安装:

  $ python setup.py install --old-and-unmanageable
  

  但请注意，这样做时您可能无法正确卸载软件包。仍然可以使用此命令，例如在您计划之后删除的虚拟环境中；

• 使用 pip 因为它能够从源目录安装包:

  $ pip install dir/
  

  其中 dir 是包含 setup.py 脚本的目录。这是首选方式； pip 将首先构建一个 wheel 文件，然后安装它。模块将平装安装(作为文件写入磁盘)，但 pip 还将在其他元数据中存储已安装文件的列表，因此所有文件都将在包卸载时正确删除。
