【问题描述】：
在 Ubuntu 系统上，我正在尝试使用 tox 和多个 python 版本测试 python 包。我尝试测试的 Python 版本之一是 64 位 Anaconda Python 2.7。在开始使用 Tox 进行测试之前，我首先需要让 virtualenv 与 Anaconda 一起使用，因为 Tox 在内部使用 virtualenv。
如你所见，我的 Anaconda 环境中已经安装了 virtualenv：
$ conda install virtualenv
Fetching package metadata: ....
Solving package specifications: ....................
# All requested packages already installed.
# packages in environment at /home/me/software/anaconda:
#
virtualenv 13.0.1 py27_0
但是，尝试创建虚拟环境失败：
$ mkvirtualenv test
New python executable in test/bin/python
Installing setuptools, pip...
Complete output from command /home/me/....envs/test/bin/python -c "import sys, pip; sys...d\"] + sys.argv[1:]))" setuptools pip:

如何让 virtualenv 与 Anaconda 一起工作？
【问题讨论】：
-
使用 virtualenv 代替 conda 环境有什么特别的好处吗？
-
@DilithiumMatrix，tox是自动生成
virtualenvs的自动测试工具。索取好处并没有真正的意义，因为你别无选择:) -
你必须首先使用anaconda吗？
