[Using Eclipse Mars (4.5.0) on OS X 10.10.5, with PyDev 4.3.0]

I recently updated by PyDev plugin from 4.2(?) to 4.3.0 and now when I attempt to debug any of my modules, I get the following error in the Console:

pydev debugger: starting (pid: 768)
Could not connect to 127.0.0.1: 49566
Traceback (most recent call last):
File "/Applications/Eclipse.app/Contents/Eclipse/plugins/org.python.pydev_4.3.0.201508182223/pysrc/pydevd.py", line 2275, in <module>
debugger.connect(host, port)
File "/Applications/Eclipse.app/Contents/Eclipse/plugins/org.python.pydev_4.3.0.201508182223/pysrc/pydevd.py", line 431, in connect
self.initializeNetwork(s)
File "/Applications/Eclipse.app/Contents/Eclipse/plugins/org.python.pydev_4.3.0.201508182223/pysrc/pydevd.py", line 418, in initializeNetwork

File "/Applications/Eclipse.app/Contents/Eclipse/plugins/org.python.pydev_4.3.0.201508182223/pysrc/pydevd_comm.py", line 379, in __init__
self.cmdQueue = _queue.Queue()
TypeError: __init__() missing 1 required positional argument: 'params'

Did I miss something on the PyDev update that I'm not doing right?

To clarify, this is only a problem with the Debug configuration - the Run config for my modules work correctly. I also uninstalled and then reinstalled PyDev, but that did not fix the problem. Thanks for any input here.

Yes! That did it - I had another module ‘Queue’ in my project. Thought I was going crazy there for a while.

In all my testing, I reverted back to PyDev 4.2.0 (have since gone back to 4.3.0) and now my list of projects/files disappears from the PyDev Package Explorer window as soon as it appears in the PyDev Perspective - ‘Refresh’ing does not help. If I switch to the Java Perspective, then the projects/files appear in Java’s Package Explorer. Suggestions as to how to reset?

Well, my guess here is that you're somehow shadowing the Queue or queue module from the standard library (depending on whether you're in Python 2 or 3) with some module of your own (as 'params' is definitely not required to create a Queue).
Cheers,
Fabio

Try changing your top-level elements in the pydev package explorer (focus
it > Ctrl+F10 > Top Level Elements).

Yes! That did it - I had another module âQueueâ in my project. Thought I
was going crazy there for a while.
In all my testing, I reverted back to PyDev 4.2.0 (have since gone back to
4.3.0) and now my list of projects/files disappears from the PyDev Package
Explorer window as soon as it appears in the PyDev Perspective -

Order has been restored - thank you. We now return you to your regularly scheduled programming.
