我现在在我刚刚从 GitHub 克隆的一些开源项目上设置工作环境，运行后
pip install -U -r requirements.txt
当然，在 virtualenv 中，我试图在fab sanity这个项目使用结构时运行，但我收到以下错误：
(openmuni)oleg@oleg-Lenovo-G580:~/dev/openmuni-budgets$ fab sanity
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/fabric/main.py", line 637, in main
docstring, callables, default = load_fabfile(fabfile)
File "/usr/lib/python2.7/dist-packages/fabric/main.py", line 164, in load_fabfile
imported = importer(os.path.splitext(fabfile)[0])
File "/home/oleg/dev/openmuni-budgets/fabfile/__init__.py", line 1, in <module>
from quilt import *
ImportError: No module named quilt
不幸的是，最简单的 2 个解决方案没有奏效：
(openmuni)oleg@oleg-Lenovo-G580:~/dev/openmuni-budgets$ pip install quilt
