Pipfile: Add build and twine

[cclauss]

Landing these two Python dependencies should make pull request #5836 easier to complete.

• https://pypi.org/project/build
• https://pypi.org/project/twine

@kalebmckale Your review, please.

Just some notes on how I did this on my M1 Mac with two terminal tabs open...

% brew install [email protected]

Error: [email protected] has been disabled because it is deprecated upstream!

---

% docker run --rm -it python:3.7 bash
---> Inside the docker container...

apt-get -qq update && apt-get install -y vim  # Or your favorite editor
git clone https://github.com/pypa/pipenv
cd pipenv
python3 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install pipenv
vi Pipfile  # Add build and twine
pipenv update --clear
pipenv shell
    # Inside shell...
    pipenv update --clear && exit
git diff  # Verify the changes
pwd
# Do not `exit` until AFTER the modified files have been docker copied out of the container!!

In another terminal tab...
% docker ps

CONTAINER ID   IMAGE                                                  COMMAND ...
413378ea9275   python:3.7                                             "bash" ...

% docker cp 413378ea9275:/pipenv/Pipfil* .
The modified files are now in the current working directory of the macOS file system.

I mean on an actual computer, it’s not a problem. On iPad, it’s not so easy. I did end up getting Python 3.7 installed, but the file took hours to go through the locking process and still eventually failed for some undetermined reason. iSH, the app I use, still has quite a few limitations to it.

On iOS, I have been involved with these two apps but they are sort of prepackaged vs. iSH.

Again, it’s not an issue of development. I personally use Pyto and Carnets. But compiling new versions of Python or running applications like locking Pipfile, as far as I know, cannot be done inside these apps. They don’t provide much of an isolated testing environment. However, I do like the convenience of developing on my iPad. It just makes some things a bit more tedious, but I generally like helping and doing what I can.
