How to run a python script with Python Tools for Visual Studio in a virtualenv?

Question

I don't know how to run the activate.bat in a Python Tools for Visual Studio Project. I have a directory environment in my project with my virtualenv. But, I don't know how I can run ./env/Scripts/activate.bat before the project run my main python script.

Answer 1

I usually point Visual Studio to a custom startup.py script, any other batch files I can then run using:

# startup.py
import os
import main.py # Whatever your main script is
os.system('activate.bat') # Call your batch files.
main.run() # Call whatever you need to from your main script.

In Visual Studio

• Right click on project
• Properties
• General
• Under Startup File, put startup.py (whatever)
• Make sure your working directory is correct

Answer 2

I found that if :

• main.py is set as Startup File,
• in the Properties of the project -> Debug tab -> Interpreter Path field, I put the path C:...\env\Scripts\python.exe (i.e. the python executable of the virtualenv)

It works !

Python Tools for Visual Studio(PTVS) 2.0 is out now, in it you can add a virtualenv.

1. Open the Solution Explorer: View > Solution Explorer

2. Right click on 'Python Environments' and choose 'Add Virtual Environment'
