含GAE的pygal ImportError

Question

我肯定我做了些蠢事，答案很简单，但我找不到.我想在GAE上使用pygal，所以我已经将整个pygal目录复制到了lib目录中。然后，导入它(从lib中的另一个文件)：

import pygal

现在我明白了：

Traceback (most recent call last):

  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 240, in Handle

    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())

  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 299, in _LoadHandler

    handler, path, err = LoadObject(self._handler)

  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 85, in LoadObject

    obj = __import__(path[0])

  File "main.py", line 18, in <module>

    from lib import output_lib

  File "lib\output_lib.py", line 14, in <module>

    import pygal

  File "lib\pygal\__init__.py", line 34, in <module>

    from pygal.graph.bar import Bar

ImportError: No module named pygal.graph.bar

我可以通过改变

from pygal.graph.bar import Bar

在pygal/__init_..py中

from graph.bar import Bar

但这将导致错误的下一次迭代：

 ...

 File "lib\pygal\__init__.py", line 34, in <module>

   from graph.bar import Bar

 File "lib\pygal\graph\bar.py", line 27, in <module>

   from pygal.graph.graph import Graph

ImportError: No module named pygal.graph.graph

所以-这里有什么问题？

由于缺乏更好的解决方案，我将所有文件导入语句中出现的所有from pygal.*替换为from lib.pygal.*。虽然我还是觉得还有别的办法..。
