我想安装一个应用程序（在Fedora上），由我们的网络开发团队的另一位成员前一段时间。香港专业教育学院管理配置几乎所有我需要在我的虚拟环境中，但是当我尝试shell命令：虚拟环境塔架版本
python setup.py install
它指向主塔的新版本，我得到的错误：
error: Installed distribution Pylons 0.9.7 conflicts with requirement Pylons==0.10
我已使用pip uninstall卸载了此虚拟环境版本的挂架，并重新安装了正确的版本。我检查了这个使用：
python
Python 2.6 (r26:66714, Mar 15 2012, 10:33:52)
[GCC 4.6.1 20110908 (Red Hat 4.6.1-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pylons
>>> pylons.__version__
'0.10'
>>>
因此，它看起来好像它仍然使用主塔系统版本的塔？该程序确实使用了一些公司的中间件，我尝试卸载并重新安装，但堆栈跟踪并没有显示出这样的错误。
这里是堆栈跟踪的其余部分：

我注意到，在堆栈跟踪它不停地下载并安装挂架0.9.7当我试图把它安装在setup.py要求文件是主塔== 0.9.7
但是，然后这不占冲突！
我设法在这里变化的要求安装该应用程序，但后来我得到一个不同的塔错误（可能是因为它过时了）
编辑
看起来是0.9.7被安装是因为它是依赖项要求的一部分。
是的，我做到了，对不起！它在副本中被切断，但我绝对在virtualenv – JackalopeZero 2012-03-16 14:59:50
