pydev debugger is not connecting

Hi, I am having the same issue with python 2.7.12 but in different lines... 

This is the Trace

Well I wast testing the new build in other environments and notices that it works. The solution, or at least what worked for me, is to delete the .idea folder of the project which seemed to be corrupt. And I back on business !

Hi Dtoro25,

You got it, fix fully working!

Thanks again!

Cheers,

JB

You're welcome +Jean-baptiste 

@Dtoro25,

I had a similar problem, but not the same resolution.

I had previously built the pydev debugger under Python 3.3 using

python /Applications/PyCharm.app/Contents/helpers/pydev/setup_cython.py build_ext --inplace.

I then had to update my project to use a new virtual environment under Python 3.5, and now the debugger won't run, with much the same message as you posted, albeit different line numbers.

Not really @Jon, everything is working for me even using Python 3.5 and other versions without problem. Perhaps you should try downloading the latest version which seems to have more fixes. I believe something was left from Python 3.3 in 3.5 and these two are incompatible... Try reinstalling too if nothing works

@Dtoro25, thanks for following up. Nothing short of creating a new project in PyCharm (on version 2016.3 no less) could get the debugger going again, which implies that there is something deeply cached on the project itself despite eliminating the .idea directory, invalidating caches, and remaking a virtual environment. Maybe that qualifies as a bug in the IDE, and I'm a little bummed that the stack trace is so short and obscure, but tracking it down any further is no where near worth the time when I can resolve it by just cloning the repo, manually moving over a little uncommitted work, and remaking the run configs. 

In my case what worked was delete all debugging breakpoints.

Thanks a lot Samuel. Your solution has solved the same problem. Go to the debug window and you'll find on the left a button with 2 red balls (breakpoints), just click it and remove all of them. That's all :)

Thank you Samuel.  That worked for me too.  I appreciated the "two red balls" hint, too, Sgalinma

I met same problem. Then I deleted .idea folder but it didn't work. 

After that, I added a breakpoint randomly.

Then my debugger got working.

Hope this could solve your problem.
