At first, I tried installing PyDev by URL in Eclipse. but it didn't work. Also, I tried moved unzip PyDev into dropin directory of Eclipse, but it didnt work and said "org.python.pydev.debug.newcosole.prefs.interactionConsolePrefs cannot be found by org.python.pydev.debug_5.2.0.qualifier".
What does it mean? and What should I do?
Also, I was said " Unable to create the selected preference page. An error occurred while automatically activating bundle org.python.pydev (542)."
