Black: Pipenv fail installation - Add documentation

[AlmogCohen]

Operating system: OSX Mohaje latest release
Python version: 3.7.2
Pipenv version: 2018.11.26
Black version: Not relevant
Does also happen on master: Not relevant, it has to do with PyPi

Seems like a very cool tool! But seems like it is not very friendly for users trying to install it using pipenv.
Simply running pipenv install black fails, probably due to what mentioned here https://github.com/python/black/issues/517. As pipenv an the official tool, the first thing people run is pipenv install black and the first thing they see is a weird failure.

You mention pip install black in the documentation, so I recommend simply adding instructions for how to install with pipenv so people don't have to google around until they find the relevant issue.

Better solution would be to just release 1.0.0 of black, so that it can be installed normally. What's the status on that? @ambv

We're hoping to release a stable release in the next few days.

Awesome work thank you, I enjoy this tool very much! Saves lots of time....

Any update on that 1.0.0? 😄

[max-wittig]

@rpdelaney See this issue: https://github.com/psf/black/issues/517

[mcauto]

Do you have an update plan about this issue?

my solution

$ pipenv install --dev black==19.3b0

[SanketDG]

How about a general update to the documentation?

Common installation options using poetry, pip, pipenv and pipx and also a note about the pre-commit hook.

I would be interested in doing a general update of the documentation to make it easier to get started in using _Black_. The only issue is that my main laptop is out of action, so I am using an old Ubuntu laptop :rofl:

[delwaterman]

This is still an issue

This happens because pipenv does not look for beta releases and black only has beta releases https://github.com/microsoft/vscode-python/issues/5171
Try it with pipenv install black --pre.
If you are installing from your pipfiles try pipenv install --dev --pre
