sys.__breakpointhook__ should be available when __builtin__.breakpoint is set (pre Python 3.7)

[fabioz]

This is because pytest checks if __builtin__.breakpoint is set but later moves on to use sys.__breakpointhook__ which wouldn't be set.

i.e.:

https://github.com/pytest-dev/pytest/blob/master/src/_pytest/debugging.py#L67

I'll submit a fix for this shortly.

I'm facing this error in VSCode 1.27.2, Python extension 2018.8.0, Python 3.6.5. When will the fix land? Any workarounds until then?

@madig One option may be applying that change locally to have it working -- specifically the change in pydevd.py in (fabioz@8c1acdf).

You create a program/execute it in debug mode with the contents:

import pydevd
print(pydevd.__file__)

to know the location of that file locally.
