What are the equivalent windows steps to setting up a virtual environment for Cookiecutters on Pylons?

Question

I am completing the Quick Tutorial for Pyramid which is written for a Linux system and I am using Windows, so I convert each command to a Windows equivalent.

In Tutorial Step: Quick Project Startup with Cookiecutters I run into the following issues:

Command written in the Tutorial: i.e. for linux

$VENV/bin/pip install cookiecutter

What I do in Windows:

I activate the virtual environment with:

c:\projects\quick_tutorial\env\Scripts\Activate

Then I use the Windows command:

(env) c:\projects\quick_tutorial\env\Scripts\pip install cookiecutter

---

Similarly, I then run the following command:

(env) c:\projects\quick_tutorial\env\Scripts\cookiecutter https://github.com/Pylons/pyramid-cookiecutter-starter

The above command places a new folder: cc_starter inside my "...env\Scripts" folder. I assume this doesn't make sense, so I move cc_starter into c:\projects\quick_tutorial.

At this point my directory looks like: My Director, which: (1) doesn't contain a "bin" folder; and (2) doesn't have the "cc_starter" folder inside the "env" folder. <-- I assume these are the 2 main differences between how this project with virtual environment should be structured differently between Linux and Windows

The Problem:

The final part of this tutorial step is to run:

$ env/bin/pserve development.ini --reload

^^ for Linux

My Windows equivalent:

(env) c:\projects\quick_tutorial\cc_starter\pserve development.ini --reload

This unfortunately returns the following Traceback (most recent call last):

(sorry about the block of text, it was copied directly out of command prompt)

Questions:

1. Do I need to run the "Activate" command, as I have done, inside the Scripts folder?
2. Is env\Scripts folder the equivalent of env\bin in Linux ?
3. Am I meant to move the "cc_starter folder" out of quick_tutorial\env\Scripts and place into \quick_tutorial? (as I have done)
4. What do I need to do to avoid error when I load development.ini?

Answer 1

First there is a PR for installing cookiecutter on Windows 10 that has been tested (by me in a VM). See https://github.com/stevepiercy/cookiecutter/blob/99250649aa3f4ba77091a72fe5df42d7f59859e6/docs/installation.rst and ping the maintainers of cookiecutter to merge the PR https://github.com/audreyr/cookiecutter/pull/887

1. We don't recommend activate. See http://docs.pylonsproject.org/projects/pyramid/en/latest/narr/install.html#venv-bin-pip-vs-source-bin-activate

   Instead use an environment variable set to the Path or invoke the command using the full path to the executable. See http://docs.pylonsproject.org/projects/pyramid/en/latest/quick_tutorial/requirements.html

2. Close enough. For Linux, substitute / for \.
3. You should not move any folders or files at this step.
4. See previous items. The last line in the stacktrace indicates that the cc-starter package could not be found, either because you relocated it or you jumped into activate, or both.

Answer 2

Found the problem! In the tutorial: Quick Project Startup with Cookiecutters, it wasn't clear that I had to complete the following commands myself:

# Change directory into your newly created project.
$ cd cc_starter
# Create a new virtual environment...
$ python3 -m venv env
# ...where we upgrade packaging tools...
$ env/bin/pip install --upgrade pip setuptools
# ...and into which we install our project.
$ env/bin/pip install -e .

After running these commands, I was able to successfully complete the tutorial. Thank you, Steve Piercy for your help.
