poetry's Issues

Support PyPI trove classifiers

Basically this sdispater/poet#5

It'd be nice to detect as many things automatically, but somewhere in pyproject.toml to manually add them would also be useful.

When I run poetry build I receive this error: [AttributeError] '_Printer' object has no attribute 'id'

Hi :)

I am trying to build a package using poetry and I am receiving and error, the steps to reproduce it are these:

poetry new example
cd example
poetry build

and it returns [AttributeError] '_Printer' object has no attribute 'id'

Do you know how to fix this error?

Is there any documentarion about the pyproject.toml and its options?

Could be great if the default pyproject.toml includes more default options

Add poetry.toml structure verification

We should implement a way to validate the poetry.toml file, both in a loose way (just for dependency management) and a strict way (for packaging).

How to add poetry to an existing project

I have an already existing project and would like to switch from pip to poetry. Basically I want to initialize an already exsting folder.

How should I do it? It seems poetry doesn't support this.

Difference with poet?

Kinda looking the same, just wondering :D

https://poetry.eustace.io/ is broken ?

Hi,

The Official site referenced in README.md looks broken. Can you confirm this ?

You can see that poetry removes more than it installed for bpython. In particular, it removed requests, which it needs to operate.

pip install -e . equivalent?

We cannot run pip install -e . because there is no setup.py. What would be the way to achieve this using poetry?

Add documentation and setup official website

poetry search with encode problems in python2.7

The search command only failed with python version 2.7.12.
I also test with Python 3.6.4 and it works fine on this version.

Command:

poetry search pagseguro

Support for PEP508

With PEP508 you can limit certain package to a specific platforms, e.g. waitress==1.0.2;platform_system=="Windows" to install waitress only on Windows.

It seem like poetry doesn't support this feature at all or at least i wasn't able to specify the constraint from above. Neither poetry add waitress==1.0.2;platform_system=="Windows" nor writing waitress = "=1.0.2;platform_system=Windows" to the pyproject.toml works.

Add support for private indices

How do I tell poetry to use python 2.7?

The README indicates that poetry supports older versions of python, but when I run poetry install in a fresh project directory it's using python 3 (the same one that poetry itself is running on). I can't find an option to specify the python version to use. I specified python 2.7 as a dependency in my pyproject.toml.

Using plugins causes TOML validation to fail

I only just rebuilt/installed a project of mine that included a plugins section. It seems when TOML validation was added in 0.6.0, the plugins section was left out of poetry-schema.json causing validation to fail.

Error on $ poetry show

[ImportError]
cannot import name 'where'

Some references not updated

There are still references to poet vs poetry in the README. And the CLI help still refers to poetry.toml vs pyproject.toml.

Are features and extras the same things ?

You mention features at to places:

You can also specify the features you want installed by passing the --f|--features option (See Features for more info)
poetry install --features "mysql pgsql"
poetry install -f mysql -f pgsql

and

When installing packages, you can specify features by using the -E|--extras option:
poet install --extras "mysql pgsql"
poet install -E mysql -E pgsql

Also the Features (See Features for more info) link leads nowhere.

SolverProblemError should provide more information about why a dependency can't be satisfied

I have a big project with lots of dependencies that I'm trying to get working in poetry. I'm getting this error when trying poetry install

  [SolverProblemError]
  Unable to satisfy the following requirements:
  - "django-imgix (^1.1.0)" required by "pyproject.toml"

Even if I pass -vvv I'm not getting any more information about what's wrong. I assume there's some conflict in the dependency tree somewhere, but I have no idea where it is. It'd be nice if poetry would print out information about what constraints have been applied to this package and where those constraints come from.

Optional dependencies are getting built as required dependencies

Given this pyproject.toml file:

[tool.poetry]
name = "example"
version = "0.1.0"
authors = [ "My Name <[email protected]>",]
description = "Example package"

[tool.poetry.dependencies]
python = "^2.7"
pytest = { version = "^3.4", optional = true }

[tool.poetry.dev-dependencies]

[tool.poetry.extras]
test = ["pytest"]

When I run poetry build, if I then go and inspect the sdist that was built, the setup.py file looks like this:

# -*- coding: utf-8 -*-
from distutils.core import setup

packages = \
['example']

package_data = \
{'': ['*']}

install_requires = \
['pytest (>=3.4.0.0,<4.0.0.0)']

setup_kwargs = {
    'name': 'example',
    'version': '0.1.0',
    'description': 'Example package',
    'long_description': None,
    'author': 'My Name',
    'author_email': '[email protected]',
    'url': None,
    'packages': packages,
    'package_data': package_data,
    'install_requires': install_requires,
    'python_requires': '>= 2.7.0.0, < 3.0.0.0',
}


setup(**setup_kwargs)

As you can see pytest has been added to install_requires and not extras_require.

hash mismatch error when a wheel has been uploaded to same version since the last lock

This is a fun one. My project depends on pluggy = "^.0.6.0" , which up until three days ago only had a .tar.gz release. Then they uploaded some wheels with the same version. I ran a poetry install today, and it seems that it's preferring the new .whl files (as it should), but then not realizing that this is a different file from the .tar.gz, so it shouldn't really be comparing to that old hash.

Here's the error I'm getting:

  - Installing pluggy (0.6.0)

Add support for non pure python projects

We should have a way to build non pure-python projects (from instance if they need to build C extensions).

Command to bump version equivalent to `npm version patch`

Would be nice to automate the semantic version bumping process with equivalents for:

npm version patch
npm version minor
npm version major
etc...

Is there a way to depend on local dependencies?

If I prefer to include my vendored dependencies directly in my repository, is there a way for me to specify them as a dependency?

e.g., if I have vendor/foo, it seems it'd be nice if I could specify a dependency like

[tool.poetry.dependencies]
foo-package = {path = "vendor/foo"}

[WindowsError] [Error 32] The process cannot access the file because it is being used by another process:

After using the custom installer to install Poetry for Python 2.7, when I try to add a dependency to a project I get this Windows Error:

Missing default required properties

After creating a new package with poetry new package, pyproject.toml is missing description and python properties probably should be auto-created.

KeyboardInterrupt

From my POV, the keyboard interrupt traceback should be omitted as it is a kind of expected error for poetry run ... calls.

Source of api/__main__.py is listed below,

```py import asyncio

import uvloop
from aiohttp import web

from api.app import create_app

if name == 'main':
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())

app = create_app()
if app['settings']['DEBUG']:
    import aiohttp_autoreload
    aiohttp_autoreload.start()

web.run_app(app, host='0.0.0.0', port=8205)

</details>

Vendorize dependencies

In order to make poetry standalone and not mess with the user system, we should probably vendorize the dependencies.

Support multiple private repositories

pip supports at least two private repositories through the combination of --index-url and --extra-index-url. It'd be nice to support any number of private repositories, but having at least two is necessary for my particular use case.

PS: thanks for this very promising project!

poetry search doesn't exist [CommandNotFound] Command "search" is not defined.

When I run poetry search requests it returns this error:

[CommandNotFound] Command "search" is not defined.

This command appears in the documentation and the README file, could you please tell me if this command will be part of poetry?

Add a remove command

We should add a remove command that would behave the opposite of add():

poetry remove requests

Support Markdown README without pandoc

PyPI now supports Markdown README files directly using description_content_type set to "text/markdown". Here is the PR that added it to the warehouse project.

Does this replace poet?

While trying to remember the exact name of this project and googling I first found your poet package which was a bit confusing.
Could you clarify what the (if any) relationship between the two is?

Also: Thanks a ton for bringing some fresh air into the python packaging world!

Does not install on mac with homebrew python

When I follow the installation instructions on my mac OS 10.13.4 using the following command:

pushd /usr/local/bin 
ln -s pip3 pip
popd
curl -sSL https://raw.githubusercontent.com/sdispater/poetry/master/get-poetry.py | python3

then I get the following error message:

I tried installing the package via pip3 directly, but that does not install a poetry executable. If instead I try to run the package`s main function then I get this error message:

$ python3 -mpoetry

Any ideas on how to get this to work?

git dependencies aren't working

It seems poetry is passing a PosixPath to execv, which needs strings. Maybe this is something that only affects Python 2.7?

Version: poetry 0.8.3

I added a print statement to see what git command was being run, that's the RUNNING GIT: part in the output.

Provide documentation for installing on macOS

I'm unclear how to actually install and use this on macOS.

According to #36 there are no plans to support hombrew's python and the recommended method is to use pyenv. However, when using pyenv, the poetry command is only available in the env you've run the install script from which doesn't really work since we use virtualenvs for all our projects.

FileNotFoundError when using add command on Windows

I've got Poetry installed using pipsi to keep it self contained from my system Python. I create a new project using Poetry then make a new virtualenv for it using Pew which launches a subshell in the new virtualenv.

Managing virtualenv

Hi,

Something nice in npm or pipenv is the management of isolation. For now, poetry is global by default (not event scoped to user installation) unless a virtualenv is already created and activated.

Do you have some plan on managing isolation with poetry ?

Étienne

Multiple entry_points being written incorrectly in wheels

They are all written on the same line. I believe this is simply due there being no fp.write('\n') inside the inner for loop in _write_entry_points.

Lower Python requirements to 3.4+ (and possibly Python 2.7)

Dependency on boto3 doesn't install botocore

I have a project that depends on boto3, but for some reason botocore isn't being installed. I checked the boto3 wheel and I see that it has a botocore dependency listed in METADATA, and pip also fetches botocore when installing into a virtualenv, so I think this might be a poetry bug.

So it would seem that install requires is being parsed incorrectly, or something!

Hope this helps
