I'm using Django and PyDev/Eclipse. I just installed django-treebeard with setup.py install and it got installed in my site-packages directory C:\Python26\Lib\site-packages. I can successfully import it in the python shell with import treebeard. However PyDev complains that it cannot resolve it when I try to import it.

Unfortunately I have no experience with PyDev and I assumed that it would automatically pick up everything in the site-packages directory but apparently it does not. What am I missing?

thanks

Pydev doesn't automatically rescan the site-packages folder. You need to go to Preferences-> Interpreter -> Python and click apply to make it scan again.

That seems a bit inconvenient but it makes sense. Should've tried that before asking, thanks for quick response.

I also faced the same error when i had installed a new package.i'm using eclipse Helios. Even after applying and re scanning the folder it was NOT detecting the new packages. So finally i clicked on the "Click here to configure a interpreter not listed" listed and deleted the already selected interpreter and used the autoconfig to add the interpreter again. Finally i was able to resolve the issue.

This was the more correct answer. PyDev does not pick up e.g. a MacPorts python install, no matter how much you rescan.

I've found that closing the project and reopening (after rescanning the interpreter) works for me.

Made the changes to the interpreter as recommended in other answers and still got errors until I closed the project. Thanks!

Well, I followed this sequence to make it work:

1) I installed the desired library by using pip install 2) I went in Eclipse to: Window --> Preferences --> Pydev --> Interpreters --> Python Interpreter, and clicked "Quick Auto-Config". It made the trick.
