Virtual Environment - Python

Hello,

I am trying to activate venv on a windows 7 computer. I am in command and entering the path correctly with activate. I am getting an error that \Python34\Lib\env\scripts\activate is not recognized as an internal or external command.

Does anyone know the correct way to activate venv?

Thank you!

If you have created a virtual environment using the command:

C:\Users\User>virtualenv venv

You can activate the virtual env using:

C:\Users\User>venv\Scripts\activate
(venv) C:\Users\User>

Deactivate using deactivate

I get an error running virtualenv. Its not recognized as an internal or external command or batchfile.

Not sure if I am missing dependencies?

On Windows, the virtualenv.exe is usually located in the python scripts directory: C:\Python34\Scripts\, C:\Python27\Scripts, etc depending on the installed version of python. This directory needs to be included in your PATH variable.

First, verify that python is on your path by typing "python" in a command prompt window.

Second, check to see if virtualenv was installed by looking for virtualenv.exe* in the python scripts directory If found, you can test it by giving the full path of the executable. The following command displays the script version number. (the .exe is optional)

C:\Python34\Scripts\virtualenv.exe --version

Next, check if the Scripts directory containing the virtualenv.exe script is on your windows path by typing "path" in a command prompt window.

If you need to change your path, look at the teacher's notes for the Using virtualenv video.
