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

Question

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

Answer 1

I found that if:

• main.py is installed as a startup file,
• in the project properties → debug tab → field “interpreter path”, I put the path C: ... \ env \ Scripts \ python.exe (i.e. the python executable for virtualenv)

It works!

Answer 2

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

• Open Solution Explorer: View> Solution Explorer

• Right-click on "Python Environments" and select "Add Virtual Environment"

Here is a video showing how to do this.

Answer 3

I usually point Visual Studio to a custom startup.py script, any other batch files that I can 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 the project
• The properties
• Are common
• In the "Startup File" section, enter startup.py (whatever)
• Make sure your working directory is correct.

Full support for Virtual Env is included with PTAS 2.0 Beta / RTM. See http://pytools.codeplex.com for news / updates. Early support for PTVS 2.0 Alpha, available now.
