Virtualenv和Anaconda问题

Question

所以这个问题之前已经提出过,但我还没有找到合适的解决方案.

我在Mac上.当我在终端中运行python时,我得到:

Python 2.7.6 |Anaconda 1.9.2 (x86_64)| (default, Jan 10 2014, 11:23:15) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

我真的不明白这意味着什么,它是用Anaconda运行Python 2.7.6吗？

无论如何,我的问题是我无法设置virtualenv.当我尝试创建虚拟环境时,我收到以下错误消息:

你能帮我找个解决方案吗？

Answer 1

virtualenv包不适用于Anaconda.在终端提示符下,您应该使用conda语句创建一个新的虚拟环境conda -n new_env_name,如文档中所述.
