I'm using PyDev installed as an Eclipse extension (through the update site) on Windows 7 and WinPython 3.6.0.1. I can run code just fine even though the syntax checker is broken, i.e., marks as error "Undefined variable: print" lines as simple as
print("hello")
I think the issue is connected with this error I get in the error log as soon as I start Eclipse:
Error creating python process - exited before creating sockets - exitValue = (1).
This is the Exception stack trace
java.lang.RuntimeException: Error creating python process - exited before creating sockets - exitValue = (1).

So, apparently the error is this
ModuleNotFoundError: No module named '_pydevd_bundle'
I tried reinstalling PyDev (it looks like the installation might be broken), but to no avail. Ideas?
I might have actually found the issue. I discovered the WinPython distribution I installed was "WinPython Zero", which comes with no additional packages. I uninstalled it and installed the "default" WinPython; now the debugger is working as expected. I suppose then there's some library needed to enable debugging. Maybe a more informative error message would help here, as this one I got really doesn't say much.
Funny thing, that's exactly what happens in PyCharm too: https://youtrack.jetbrains.com/issue/PY-24198
