Python导入/查找名称中带有句点的软件包

Question

Using Ubuntu 14.04.

I'm installing someone else's python program, and encountering some trouble in installation and running it.

They have an install shell script; and it currently runs completely through.

When I run the executable python program 'dwgui', i get an error on the line:

File "./dwgui", line 6, in <module>
    from dw.gui.dw_gui import MainWindow
ImportError: No module named dw.gui.dw_gui

The install shell script is very verbose, and it's output indeed says:

copying build/lib.linux-x86_64-2.7/dw/gui/dw_gui.py -> /home/ubuntu/.local/lib/dw/gui

and then:

byte-compiling /home/ubuntu/.local/lib/dw/gui/dw_gui.py to dw_gui.pyc

so there is a dw/gui/dw_gui.pyc file. (I checked) Is there any way to get that dw.gui.dw_gui package to import and be used?

您需要确保/home/ubuntu/.local/lib/目录位于PYTHONPATH环境变量上。
