问题 I just ran my website made with Django1.3 for the first time on Heroku. I had to change every mentioning of myproject into app (such as import myproject.core.views into import app.core.views in urls.py ) in order to make my website run without an importError .

问题 I am trying to write a plug-in for Audacious Media Player that loads a python module. The python embedding code is from the python-2.6 source(embed/Demo). This compiles with the command line, gcc -o demo demo.c -lpython2.6 -lm -L/usr/lib/python2.6/config I added -lpython2.6 -lm -L/usr/lib/python2.6/config to the CC args. And it loads a Python script which imports pygtk and gtk modules, this works fine. But after I compile the plug-in(a shared library) the following error occurs(this is not
