当我启动金字塔保存时，我得到这个堆栈跟踪：
% python $(which pserve) ../etc/development.ini

ImportError: No module named views
这在 python REPL 中工作得很好：
% python
Python 2.7.5+ (default, Feb 27 2014, 19:37:08)
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ponder.server.views import Endpoints, route
>>>
并从命令行导入：
% python -c "from ponder.server.views import Endpoints, route"
一个删节的tree输出显示我正在处理的内容：
% tree

│ │ ├── environment_templates.py

My PYTHONPATH设置为该树的根：
% echo $PYTHONPATH
/home/hughdbrown/workspace/ept/ponder/lib
我正在使用 python 2.7 的 virtualenv 中运行它。我今天断断续续地工作过，但我不知道问题出在哪里。一方面，__init__.py似乎没问题some之前的导入：
from .database import get_db
from .config import parser
from .views import Endpoints, route
（我将最后一行更改为绝对导入。不走运。）
我尝试过的事情：
重建虚拟环境
Setting PYTHONPATH
在代码中使用绝对路径
寻找循环进口
我愿意接受有关如何调试此错误的进一步建议。
所以我犯的错误是只查看源代码树。问题确实出在运行时环境中，在我的 virtualenv 中。当我查看那里时，我发现所需的文件没有安装。问题的根源在于setup.py.
