python - Virtualenv 和 Anaconda 问题

Question

所以这个问题以前也有人提出过，但是我还没有找到合适的解决办法。

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

我不太明白那是什么意思，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，我收到此错误消息:

你能帮我找到解决办法吗？

Answer 1

virtualenv 包不适用于 Anaconda。在终端提示符下，您应该使用 conda 语句 conda -n new_env_name 创建一个新的虚拟环境，如 in the docs 所述.
