我在安装 goose 时遵循了https://github.com/grangier/python-goose的确切说明，在输入“mkvirtualenv --no-site-packages goose”后，我得到了：
172-27-220-167:~ yitongwang$ mkvirtualenv --no-site-packages goose
New python executable in goose/bin/python
Installing setuptools, pip...done.
Error: deactivate must be sourced. Run 'source deactivate'
instead of 'deactivate'.
Usage: source deactivate
removes the 'bin' directory of the environment activated with 'source
activate' from PATH.

我已经使用'sudo pip install virtualenv/virtualenvwrapper'安装了virtualenv和virtualenvwrapper，最奇怪的是我似乎仍然设法进入goose虚拟环境（似乎是这样）。克隆到 git repo 并切换到之前克隆的目录 python-goose 后，我尝试运行“pip install -r requirements.txt”和“python setup.py install”，这些是错误：

我不确定具体出了什么问题，因为我从头开始尝试了几次，我删除了目录“python-goose”和“./virtualenv”以及来自 .bash_profile 的路径。
任何帮助将不胜感激！
谢谢
PS 我正在使用带有 Python 2.7 的 Anaconda。
