virtualenv错误？

我想在我的virtualenv运行以下脚本：virtualenv错误？

(python2.7.2-gonvaled1)[email protected]:~/.virtualenvs/python2.7.2-gonvaled1$ couchy.py 
Traceback (most recent call last):

    from __future__ import unicode_literals 
SyntaxError: future feature unicode_literals is not defined

所以不知何故蟒蛇正试图从导入：

/usr/lib/python2.5/site-packages/starpy/utilapplication.py

这没有任何意义。我的virtualenv很干净：

和：

(python2.7.2-gonvaled1)[email protected]:~/.virtualenvs/python2.7.2-gonvaled1$ pip freeze 
CouchDB==0.9dev 
DateUtils==0.5.1 
Twisted==12.0.0 
basicproperty==0.6.12a 
pystache==0.4.0 
python-dateutil==2.1 
pytz==2012b 
simplejson==2.4.0 
six==1.1.0 
starpy==1.0.0a12 
wsgiref==0.1.2 
zope.interface==3.8.0

所以总结：Python是从/usr/lib/python2.5/site-packages进口，即使我是一个的virtualenv内。怎么会这样？

尝试运行脚本：

$ python couch.py

在你激活的virtualenv

。根据您的系统和文件的第一行（shebang行），您可能没有在您认为自己的Python中运行。

谢谢，就是这样。我的shebang是'＃！/ usr/bin/python'。我觉得有点讨厌，我不能自己运行我的Python脚本。这意味着，为了在虚拟环境中运行它们，我必须做一些与我在主机环境中做的不同的事情。它有效地杀死了shebang的概念，因为要做到这一点，我不能依赖它（认为控制脚本，cronjob等）。我试图把'＃！python'放在shebang中，但显然绝对路径是必需的。 – dangonfast 2012-03-29 05:17:41

使用'＃！/ usr/bin/env python'的shebang行。这应该使用在当前'$ PATH'上找到的第一个'python'，它应该是活动virtualenv中的一个。 – 2012-03-29 08:51:35

这很有道理，谢谢。我会尽快尝试。 – dangonfast 2012-03-29 10:18:42

你应该使用--nositepackages选项创建你的virtualenv选项，以保持它的干净，远离你的系统Python。

不，不，我已经说过我的virtualenv很干净。它实际上是使用'--nositepackages'创建的（顺便说一句，在virtualenv的最新版本中不再需要，因为它已经成为默认版本） – dangonfast 2012-03-29 05:19:11

virtualenv错误？
