我有一个要求文件，我正在安装几个软件包。当我pip install第一次在新环境中运行时，它们会按应有的方式安装。此后，我的大多数软件包都正确报告“要求已经满足”并且不再安装。

但是，出于某种原因，我的一个包是每次都“安装收集的包”，执行 setup.py 等。这实际上是我自己的内部库，它托管在我自己的服务器上并通过 git+ssh 安装。

下面来看看发生了什么。（该库称为 django-supplement。）

$ pip install -r requirements/production.txt 
Requirement already satisfied (use --upgrade to upgrade): django from git+https://github.com/django/django.git@1.6b2#egg=django in ./lib/python2.7/site-packages (from -r requirements/production.txt (line 3))

Cleaning up...

这是 setup.py 在 django-supplement 中的样子：

import os
from setuptools import setup, find_packages

# Utility function to read the README file.
# Used for the long_description.  It's nice, because now 1) we have a top level
# README file and 2) it's easier to type in the README file than to put a raw
# string in below ...
def read(fname):
    return open(os.path.join(os.path.dirname(__file__), fname)).read()

setup(
    name = "django_supplement",
    version = "1.6.1",
    author = "Jim Dalton",
    author_email = "XXXXXXXX",
    description = "Common helpers for django",
    license = "BSD",
    packages=find_packages(),
    long_description=read('README'),
    install_requires=["markdown2 >= 1.0.1.19"],
)

所以我想做的是找到一种方法让我的库像普通库一样运行，并为给定版本安装一次，否则报告“要求已经满足”，除非我使用 --upgrade 标志或其他任何东西。

仅供参考，我关心的原因是我现在正在 Ansible 中配置一个项目，并且它报告“已成功安装...”的事实导致 Ansible 认为发生了变化，这会触发我更喜欢的其他操作避免在配置过程中。

好吧，我解决了这个问题，但我不知道为什么。我想我传递给 setup 的名字 kwarg 与某些东西不符。重命名为 django-supplement 解决了这个问题。
