从virtualenv运行依赖于库的python脚本

我正在尝试运行一个朴素的bayes脚本，它需要NumPy、SciPy和Pandas来运行。为了避免与Macs10.7上python的多个副本混淆——而且因为我不知道如何实现，所以我制作了一个virtualenv，并在那里安装了NumPy和SciPy，运行后进行检查

$ python
>>> import numpy
>>> import scipy

一切正常。现在，我在文件的目录中，运行

python nb\u predict.py

会给我带来很多错误

最初，文件顶部python编译器的路径是

#!/usr/local/bin/python

但由于我不知道在虚拟环境中安装了所有内容后是否发生了更改，我尝试了以下方法：

#!/Users/myusername/.virtualenvs/scipy/bin/python

但它仍然不起作用。我也使脚本可执行

请，任何帮助都将不胜感激

这就是我得到的错误：

#！。。。站点包

可能无法工作，因为

站点包

是一个目录（不是程序）。你可以试试

#/Users/myusername/.virtualenvs/scipy/bin/python

如果它有效，那么您可以使用

#/usr/bin/env python

shebang并在virtualenv处于活动状态时运行脚本，或者使用

setuptools

“入口点编写

setuptools

”自动生成具有正确shebang的脚本。对不起，这就是我的意思。我使用“#！/Users/myusername/.virtualenvs/scipy/bin/python”运行它，它返回了上面的错误。我在尝试编写配置或设置脚本时感到有点谨慎，我想知道是什么导致了这些错误。这是一个路径/路由问题。

python-mnumpy.distutils.system\u info

是否成功完成？

哪个python

指向

？未找到此->

符号：\uuuuuuu sincos\u stretc

看起来很重要。这些命令用于声明明显的内容（使用python的安装）。谷歌搜索

\uuuuuu sincos\u stretc

显示，如果您使用正确的Xcode版本重新编译安装，则

scipy

安装可能已修复。你试过了吗？
