My old computer died. Here's my chance to start fresh using virtual environments.

I started with a fresh install of python 2.7.18 and 3.7.9 on a new Windows 10 computer. (It doesn’t matter if I install python 3.7.9 for all users or just one account. I’ve tried both with the same results.)

I want to set up **venv** for python 3. (I tried with **venv** and **virtualenv** with the same results.)

I go to my project directory and type:

```
py -3.7 -m pip list

>Package    Version
>---------- -------
>pip        20.2.3  
>setuptools 47.1.0

```

I create a virtual environment for my project.

```
py -3.7 -m venv venv

```

and activate the virtual environment.

```
venv\Scripts\activate.bat

```

The prompt changes to show I’m using the virtual environment.

```
py -3.7 -m pip list

>Package    Version
>---------- -------
>pip        20.2.3  
>setuptools 47.1.0

```

Now I install a daily build of wxPython to the virtual environment.

```
py -3.7 -m pip install "d:\((username))\Downloads\Python\python3.7-64\wxPython-4.1.1a1.dev4959+47c4a913-cp37-cp37m-win_amd64.whl"

```

This successfully installs wxPython. The prompt shows I’m still in virtual environment. I confirm the installation.

```
py -3.7 -m pip list

>Package    Version
>---------- ------------------------
>numpy      1.19.2   
>Pillow     7.2.0   
>pip        20.2.3   
>setuptools 47.1.0   
>six        1.15.0   
>wxPython   4.1.1a1.dev4959+47c4a913  

```

This is just what I expect. I now deactivate the virtual environment.

```
deactivate

```

The prompt changes, so I am no longer using the virtual environment. But

```
py -3.7 -m pip list

>Package    Version
>---------- ------------------------
>numpy      1.19.2  
>Pillow     7.2.0  
>pip        20.2.3  
>setuptools 47.1.0  
>six        1.15.0  
>wxPython   4.1.1a1.dev4959+47c4a913  

```

That's not what I expected. I thought wxPython (along with numpy, Pillow, and six) would no longer show up. Looking at where files are added, I see that the pip changes are made to C:\Users((username))\AppData\Local\Programs\Python\Python37\Lib\site-packages, not to D:((username))\Documents\Programming\Python((projectname))\venv\Lib\site-packages, which is what I expected.

And when I start Python 3.7.9 again, I still have all the packages installed without loading my virtual environment. So the whole virtual environment concept is totally ignored.

Can anybody help me understand what I've done wrong, and more importantly, what I need to do differently?

Thanks
