于是我打开一个终端，cd到我的桌面，然后运行：的virtualenv混乱
virtualenv test_env
然后我在我的正常环境中创建以下文件：
/home/jesse/.local/lib/python2.6/site-packages/foo_package/__init__.py
此文件包含一行：
print "importing from normal env"
在test_env创建：
/home/jesse/Desktop/test_env/lib/python2.6/site-packages/foo_package/__init__.py
包含：
print "importing from test env"
现在我打开一个终端，运行：
$ /home/jesse/Desktop/test_env/bin/python
然后执行：
>>> import foo_package
，输出：
为什么不将它导入从test_env文件？我认为这是virtualenv的重点。我在这里错过了什么吗？
编辑：乔恩H告诉我，我需要激活环境。但这似乎不能解决问题...

这看起来像是前进的一步，因为test_env东西出现在路径中，但它仍然不起作用。我认为我目前的问题是'/home/jesse/.local/lib/python2.6/site-packages'出现在'/home/jesse/Desktop/test_env/lib/python2.6/site-packages '
编辑4：罗杰建议使用--no-site-packages选项创建env。我试过了。同样的问题。

再次，它看起来像这个问题是在我的“当地的”站点包更早出现在比‘test_env’的站点包的路径。
什么是您的virtualenv设置为sys.path？ – Haes 2009-10-26 13:18:00
