Python version: 3.7.1

Expected behaviour

Run python program in integrated terminal

Actual behaviour

Won't start program in integrated terminal. Timeout waiting for debugger connection.

Steps to reproduce:

• create new folder
• from integrated terminal run command "pipenv install pylint" (inside that folder)
• create helloworld.py
• run in mode "Python: Current File (Integrated Terminal)"

Comments and possible cause:

• Program does work when started in "Python: Current File (External Terminal)" mode
• First command that gets executed is penv shell, and it used to be ...\activate.ps (What is the reason behind this change?). Seems like command for executing program is broken into two pieces one executing in powershell and the other in pipenv shell. See:

• There is a workaround: stop waiting for debugger (clicking on red square in top right corner), and starting again in same mode:
