PyDev未解决的导入与sklearn

Question

I'm running PyDev in Eclipse 4.2 on Mountain Lion. I installed the SciPy Superpack , and can use all the packages -- including Scikit-learn and MatPlotLib -- in the Python interpreter and through IPython. However, when I try to import them in PyDev I get an 'Unresolved import' error.

I installed Python 2.7.3 from Python.org, and verified that PyDev is pointing to the correct interpreter. I also attempted to add the sklearn and matplotlib directories (verified via the path from sklearn.__file__ ) to the System PYTHONPATH in the PyDev settings. This didn't resolve the issue.

Any idea what else I should try?

From your comment examples, seems the path you are using is at the wrong depth.

Change from:
/Library/Python/2.7/site-packages/scikit_learn-0.12_git-py2.7-macosx-10.8-intel‌​.egg/sklearn

To:
/Library/Python/2.7/site-packages/scikit_learn-0.12_git-py2.7-macosx-10.8-intel‌​.egg

It wasn't able to find the package level name because you were specifying beneath it. Normally a python interpreter will resolve all the eggs by simply existing insite the site-packages, from the `.pth' file references that get placed there. But I think pyDev will need explicit adding of those eggs to the PYTHONPATH.
