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

[JelleZijlstra]

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

[hectormirete]

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

This is a problem because that adds an option that allows pre-releases for any dependency. See https://github.com/pypa/pipenv/issues/1760.

IMO this comment above is currently the best solution: https://github.com/psf/black/issues/822#issuecomment-635004328

PS C:\Users\user\Documents\GitHub\my-pytest\api\my_pytest_app> pipenv install --dev --pre black Installing black... WARNING: Expecting property name enclosed in double quotes: line 13 column 50 (char 347) Installation Failed

Not sure how to resolve this , have tried all different commands mentioned above. Can someone help thanks

[ambv]

Praveen, it's hard to help you without you specifying versions of all things. I suspect you're trying to install Black with Python 2.

[praveen868686]

Hi this is the command I am trying to use and error as below. Python 3.9.6 version pipenv install black --pre Installing black... WARNING: Expecting property name enclosed in double quotes: line 13 column 50 (char 347) Installation Failed

My pip file: [[source]] url = "https://pypi.org/simple" verify_ssl = true name = "pypi"

[packages] pytest = "" djangorestframework = ""

[dev-packages]

[requires] python_version = "3.9"

[pipenv] allow_prereleases = true

thanks

pipenv install --dev black==19.3b0

[frob]

I see there is a release now. Still cannot install with pipenv unless I set the version like in the above comments.

[JelleZijlstra]

We have a stable release now, which appears to solve the original problem in this issue. If you're still having problems using Black with pipenv, please open a new issue explaining exactly what is going wrong.

[AlmogCohen]

At last! Thank you 🙏😊 Absolutely useful project for the entire community!

[JelleZijlstra]

The first stable release was in January actually :)

[AlmogCohen]

Oops, didn't notice...Too much Typescript lately 😉
