我从这个 git 存储库创建了一个分支：https ://github.com/QQuick/Opy
我将一个添加__init__.py到目录/包中opy。当我运行时setup.py install，该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 = [

总结一下评论中的陈述：
setuptools.setup尽其职责；然而，不是仅仅将模块复制到site-packages（distutils做什么），而是python setup.py install构建一个 Egg 文件，然后通过简单地将其复制到site-packages. 这样，之后只需删除一个 Egg 文件即可轻松卸载该软件包。
如果您不喜欢将软件包安装在存档中，您可以：
进行“旧且难以管理”的安装：
$ python setup.py install --old-and-unmanageable
但请注意，执行此操作时您可能无法正确卸载该软件包。尽管如此，该命令仍然可以在例如您计划随后删除的虚拟环境中使用；
使用pip它可以从源目录安装包：
$ pip install dir/
其中dir是包含脚本的目录setup.py。这是首选方式；pip将首先构建一个wheel文件，然后安装它。这些模块将被平面安装（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软件包卸载时正确删除。
