Poetry: Install globally with --user

Feature Request

I am using Poetry to install project dependencies into a Docker container where I do not have root access. Since using a virtualenv would be unnecessary (there is only ever one project in this container) and a waste of time (this is done as part of a web service aiming at speed), I configure settings.virtualenvs.create to false. However, this causes Poetry to try to install the packages system-globally, which fails because I don't have root access in the container.

I would like a way to tell Poetry to use pip install --user instead of just pip install to install packages when virtualenvs are disabled.

I picked up this issue and started working on an implementation

Can somebody re-open the issue please? cc: @sdispater

Hey @richin13 ,

thanks a lot for your contribution! I reopened this issue and assigned you for seeing that this is in progress.

As this is a new feature @sdispater has to decide if it gets included. But it looks like a useful thing to me :+1:

Awesome, thank you @finswimmer

Shouldn't the following just work?

pip install --user /path/to/poetry-project

This should result in your project being built in an isolated environment without development requirements and pip installing the built package respecting the --user flag.

@richin13 did your submission go anywhere or was it ignored? Currently my workaround is:

pip install --user --requirement <(poetry export --format requirements.txt)

However, this doesn't give me the project itself installed into the user.

I also tried setting PIP_USER=1 hoping that it would get passed through poetry down to the underlying pip command, but no joy.

@harrybiddle why not let pip install the project itself as suggested above?

@raxod502 @richin13 I beleive this behaviour is dependent on the underlying pip version (ie. the pip provided in your container). This often times (if ensured via python -m ensure pip) tends to be older versions.I beleive since 20.0, pip defaults to installing to user site when not root. Trying a pip install --upgrade pip prior to doing poetry install might do the trick here.

Hey @abn, thanks for the help, I really appreciate it.

I just gave this a go and it worked, except for two things: (1) my dev dependencies didn't get installed, and (2) I think your command installs the dependencies in the pyproject.toml rather than the pinned dependencies in poetry.lock, is that correct?

I couldn't see an option to pip install to pick up dev dependencies from pyproject.toml, and I played around with its --constraint option, but could not get it to work. In the end I came up with this command (pip 20.2.2, poetry 1.0.10):

pip install --requirement <(poetry export --dev --format requirements.txt)
pip install --no-deps .

This works where poetry config virtualenvs.create false && poetry install fails on Ubuntu 18.04 (it fails uninstalling system packages).
