Eclipse+pydev cannot find the corresponding module not in Pythonpath

When you use Eclipse +pydev to debug Python, hold down the CTRL key and you can usually go to the corresponding method.

But if you don't, you'll see yellow in eclipse, but you can't get into the sub-method.

If the mouse moves on the corresponding method, will pop up the prompt said: "_module not in Pythonpath", that should do? Speed up the debugging method.

Mac words, is to enter eclipse-> preferences

Open the Preferences page, go to the Pydev option-->interpreters-->python interpreters, choose New Folder, add the items you want is OK.
