running inside tox uses unvendorized dependencies #848

gaetano-guerriero · 2019-01-30T11:23:32Z

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).
OS version and name: Debian testing
Poetry version: 0.12.11

Issue

I'm trying to use poetry inside tox following instructions in #222.

I think that when installing the local package inside virtualenv created by tox a new poetry is used using dependencies from surrounding virtualenv.

If the project has dependency conflicting with poetry dependencies the installation fails.

My conflicting dependency is jsonschema, jsonschema ^2.6 used by project is not compatible with jsonschema 3 used by poetry.

`pyproject.toml`

[tool.poetry]
name = "foo"
version = "0.1.0"
authors = "me"
[tool.poetry.dependencies]
python = "^2.7"
jsonschema = "^2.6"

[tool.poetry.dev-dependencies]
tox = "^3.0"

[build-system]
requires = ["poetry>=0.12"]
build-backend = "poetry.masonry.api"

tox.ini

[tox]
envlist = py27
skipdist = True

[testenv]
whitelist_externals =
    poetry
skip_install = true
commands =
    poetry install -vvv

I confirm this bug happens.

This also happens to me. I have not found a workaround yet, it would be helpful if this was fixed so that I could use poetry as the build-system.

You should use isolated builds as explained in the documentation: https://poetry.eustace.io/docs/faq/#is-tox-supported

`tox.ini`

wfscheper · 2019-05-07T16:53:53Z

I believe the issue here is that poetry doesn't have a way to specify build dependencies separate from runtime dependencies. Here's the problematic code:

def get_requires_for_build_wheel(config_settings=None):
    """
    Returns a list of requirements for building, as strings
    """
    poetry = Poetry.create(".")

    main, _ = SdistBuilder.convert_dependencies(poetry.package, poetry.package.requires)

    return main

Ideally, poetry would either have a separate section for build dependencies, aladev-dependencies, or a way to flag a dependency as a build dep, ala allows-prerelease.

aizelauna · 2019-06-07T13:28:33Z

I have a very similar issue.
The strange thing is that I have configured three environments (py27, py36, py37) in tox.ini file and only the 2.7 fails.
My exception log is slightly different:

funkyfuture · 2019-06-20T14:40:12Z

I think that when installing the local package inside virtualenv created by tox a new poetry is used using dependencies from surrounding virtualenv.

i tried upgrading jsonschema of the 'surrounding' virtual environment, but 2.6 will still be installed in the .tox/.package venv. the same is true when no virtual environment is active and jsonschema isn't available at all. it still yields this error.

i also specified this in the pyproject.toml, but with the same result:

[build-system]
requires = ["poetry>=0.12.16", "jsonschema>=3.0"]
build-backend = "poetry.masonry.api"

thus, i wouldn't be sure whether an 'outer' jsonschema is causing this. i'm currently motivated to dig into this, so any proposals where or what to dig for would be appreciated.

funkyfuture · 2019-06-20T17:48:41Z

for what it's worth, switching to nox and using an 'outside' poetry installation is not an option.

edited after i noticed that the wrong interpreter is used.

jimmyharris · 2019-09-25T21:12:35Z

I had a similar problem with a project based around docker-compose. Docker compose requires jsonschema < 3 in its current release, so I had to downgrade my in-envrionment poetry install to 0.11.5 (the last version released that did not have the higher jsonschema requirement. It makes me wonder if moving to the newest jsonschema for 0.12 was really a wise idea.

pmav99 · 2019-09-26T06:48:38Z

@jimmyharris docker-compose, like poetry itself should be installed in a different python distribution than the one you are developing. That distribution might be the OS one, or a different virtualenv. I usually install docker-compose using pipx

jimmyharris · 2019-10-08T16:51:29Z

Generally this is true but I am actually building a project that extends docker compose programmatically and i can’t guarantee that my tools will be correctly installed my ci group.

pikacic · 2019-11-02T03:55:32Z

I just stumbled on this problem when trying to enable tox integration in my poetry managed project.

In my case the issue comes from the dependency on cleo = ^0.7.

The first failure is when, preparing the build venv, tox asks poetry which are the build dependencies of my project (in this case "cleo>=7.0,cleo<0.8", but poetry requires "cleo<0.7"), then tox upgrades the version of cleo in the same venv, and that makes the previously installed poetry unusable.

I tried to follow up on @wfscheper suggestion, by making get_requires_for_build_wheel to return an empty list (after all I only need poetry and its dependencies to build the wheel), but it's not enough, because now I get a failure in the testenv (before it was in the buildenv).
This time the error message in the log file is a bit more useful:

ERROR: Some build dependencies for file:///some-path/test-848/.tox/.tmp/package/1/test-848-0.1.0.tar.gz conflict with the backend dependencies: cleo==0.6.8 is incompatible with cleo<0.8.0,>=0.7.6.

So I deduce tox requires the build backend and the project to have compatible dependencies, even if we require isolated_builds = true.

I would suggest, at least, to clarify this point in the documentation.

pikacic · 2019-11-02T04:31:46Z

Actually I just realized it's not tox that imposes that build and runtime dependencies have to be compatible: it's pip itself.

I just tried to call pip install . on my project (I only have a pyproject.toml and no setup.py) and I got:

pip._internal.exceptions.InstallationError: Some build dependencies for file:///home/marco/Devel/workspace/nightlies-jenkins-scripts/lb-jenkins conflict with the backend dependencies: cleo==0.6.8 is incompatible with cleo<0.8.0,>=0.7.6.

This also makes my problem similar to #826 too.

schinckel · 2019-12-06T02:37:02Z

I believe that the suggested way of installing using poetry in tox does not install to an isolated environment: I'm not sure if this is what is causing this issue, but I think it exposes some issues about the way poetry works, that mean it cannot work with tox to ensure a fully isolated test run.

Instead of installing packages to the tox environment that is currently active, it installs to the same environment that is used in development. Whilst this works, it does not feel like it is the correct approach - the point of tox is that it is an isolated test environment, and thus should be an isolated virtual environment too.

It is possible to indicate to poetry that it should not create a virtual environment: but this does not appear to change if poetry will use a virtual environment - in my tox test runs it still installs to the same location (or, more specifically, indicates that it doesn't need to install).

Likewise, there is a setting that indicates that it should use an "in-project" virtualenv. However, this appears to not work either: it still installs to my "development" virtualenv.

But, setting config values from within a tox environment test run is not a satisfactory pathway when using poetry anyway: all poetry config ... commands write to the user's global poetry settings: there does not appear to be a way to have configuration that only applies to this current execution of poetry.

Pipenv avoids this problem by automatically installing to the current virtualenv if it detects one: but I think an alternative solution could be to allow setting which virtualenv should be used to install to.

Issues #1745 and #1941 might be related.

From my point of view having poetry install and poetry run in the tox commands does not make much sense, since tox already takes care of installing the project (via the sdist built thanks to isolated_build = true) and its dependencies in a virtual environment. If somehow tox had a a way to read and install the dev-dependencies instead of the run-time dependencies then the integration would be much smoother. Maybe the development dependencies should simply be listed in an extra instead.

The original issue should not exists anymore. That's why I'm closing this thread.
