我遵循了https://github.com/grangier/python-goose在安装鹅的时候，在我输入"mkvirtualenv--no site packages鹅"之后，我得到的是：
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鹅虚拟环境（看起来像这样）。在克隆到git repo并更改到之前克隆的python-goose目录后，我尝试运行"pip install-r requirements.txt"one_answers"python setup.py install"，错误如下：

我不确定到底出了什么问题，因为我已经从头开始尝试过几次，删除了目录"python-goose"one_answers"/virtualenv’以及来自.bash_profile.的路径
任何帮助都将不胜感激！
感谢
附言：我使用的是带有Python 2.7的Anaconda。
看看这个。这里也强调了同样的问题。它与/usr/local/bin/virtualenvwrapper.sh中的工作相关，并调用deactivate，但anaconda-bin目录中的脚本也做同样的事情。
不要使用virtualenv，而是尝试使用conda（conda create）创建一个环境，并将所有的鹅依赖项安装到其中（显然freetype就是其中之一）。然后将鹅直接安装到那个环境中。类似于conda create -n goose freetype ...（用鹅的其他依赖项替换...）、source activate goose、python setup.py install（来自鹅目录）。
