In a nutshell, Poetry is a tool for dependency management and packaging in Python. open() in Python does not create a file if it doesn't exist. But if it's not, it will use one that it has already . I was yearning for a single tool to maintain isolated environments, manage dev and production dependencies, packaging, and publishing. The following is a set of guidelines for contributing to Poetry on GitHub. This might not be ideal but for a specific setup this seems to work well. Would Poetry maintainers be open to adding a similar config such as virtualenvs.ignore-conda-env to Poetry? still ignoring the "not create virtualenv" directive. as you said, the .bashrc approach does not activate the venv inside the Dockerfile so poetry run has to be used for any RUN/ENTRYPOINT/CMD commands which need the environment - not ideal but works. It's useful in docker and possibly in other use cases too. All Rights when a new virtual environment is created, pip will not be installed in the environment. There are many tools that are not tied to any specific virtualenv and are supposed to work with each of them . Poetry is aiming to improve the common use case while not inventing a parallel universe where it makes decisions incompatible with other tools, or where you are forced to use Poetry exclusively and not integrate it into existing workflows. Reserved. One use case for specifying the path to the venv I can imagine, is when you run out of space and one need to put the venv files to a different location. We value full transparency and painful honesty both in our internal and external communications.

First, ask pipenv where the actual virtualenv is located with the following command: It will output the path to the virtual environment and all of its files and look similar to the example above. poetry 1.2.2 refuses using the existing virtual environment with the suggested solution: With virtualenvs.create true, it just goes and creates a virtualenv in its cache directory. Private Repository Example Installing from private package sources By default, Poetry discovers and installs packages from PyPI.. Poetry makes project environment isolation one of its core features. Poetry can be configured via the config command (see more about its usage here) or directly in the config.toml file that will be automatically created when you first run that command. See Repositories - Configuring credentials - Custom certificate authority While the dependency resolver at the heart of Poetry is highly optimized and should be fast enough for most cases, with certain sets of dependencies it can take time to find a valid solution.

New projects should start with a fresh virtual environment to ensure only dependencies needed are installed. A workaround (I haven't tested) might be as follow: When settings.virtualenvs.in-project (virtualenvs.in-project in poetry v1.0.0) is set to True, poetry expect the venv files in the .venv folder inside the project.

This configuration is only respected when using the new installer. The downside of the isolation of poetry running in its own venv is, that it is hard to find out which python is currently activated in the shell and therefore where the global place for installing packages is. Edit: It looks like the a project-specific virtualenvs.options.system-site-packages = true config option as requested in #2937 might solve my issue. An important thing, I'm trying to do it in a Dockerfile. Reserved. I am not sure how internally this works, but the following workflow would be very useful: After doing this, it would be very nice if this or something similar could store information about the choice of environment in poetry.toml or something so that running poetry shell from within the project first activates the my_conda_env (until poetry env use or similar is called in the future).
