Poetry always updates packages when installed to system python

[artslob]

• 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: Linux Debian (in docker)
• Poetry version: 1.0.3
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/artslob/1e3d70f8e93f85c2a4ab989332edf170

Issue

In gist link I attached Dockerfile, pyproject.toml and poetry.lock files. Issue is when building docker image I used poetry config virtualenvs.create false to install dependencies to current system python interpreter. It works, but executing poetry install several times always updates some packages, which already installed:

But if set poetry config virtualenvs.create to default (to true) and create and activate virtualenv, then several poetry install works as expected and exit fast, because all packages already installed:

Installing dependencies from lock file

No dependencies to install or update

I have this problem too, but in my case I'm not using the system Python, it seems to be to do with private repos. I'll mention it here since the symptom is the same. I fixed it by removing type = "legacy" from all the package references in my poetry.lock since a new project I checked didn't have the same problem, and it didn't have that.

I see the same in a self created venv created via python -m venv venv with poetry 1.0.5.
Repeated poetry install always updates all packages although they are already up to date:

[artslob]

Looks like it was solved in #1981 (issue #1883) and relesead in 1.0.4. I tested in 1.0.5 and repeated install command now prints No dependencies to install or update as expected.

Do not close issue because of @flokno message.

[trim21]

I guess they are not same bug. Package in vendor is not recognized as installed packages here. And I can't reproduce it, either.

[HodeiG]

I was experiencing the same issue with poetry 1.0.9.

I managed to narrow down the issue to some old "export PYTHONPATH" in my .bashrc file. After getting rid of that export, the issue went away.

[optional] Debugging steps:
Basically, in poetry/repositories/installed_repository.py I noticed that one of the entries '/home/hodei/src/my_package' would fail at

poetry/poetry/repositories/installed_repository.py

Line 59 in b19873a

path.relative_to(src_path)

:

ValueError: '/home/hodei/src/my_package/my_pakcage.egg-info' does not start with '/home/hodei/src/my_package/.venv/src'

Due to the above, all the packages "source_type" were getting marked as "directory" type. Later on, during the installation because of the different "source_type", at line

poetry/poetry/puzzle/solver.py

Line 95 in b19873a

elif pkg.source_type and package.source_type != pkg.source_type:

, all the packages were getting marked for an update, causing the problem described in this Issue.

Before removing the export, my sys.path was:

$ echo $PYTHONPATH 
/home/hodei/.local/lib/python/site-packages:/home/hodei/local/lib/python2.7/site-packages:
$ cd src/my_package
$ source .venv/bin/activate
$ python -c "import sys; print(sys.path)"
['', '/home/hodei/.local/lib/python/site-packages', '/home/hodei/local/lib/python2.7/site-packages', '/home/hodei/src/my_package', '/home/hodei/.pyenv/versions/3.7.7/lib/python37.zip', '/home/hodei/.pyenv/versions/3.7.7/lib/python3.7', '/home/hodei/.pyenv/versions/3.7.7/lib/python3.7/lib-dynload', '/home/hodei/src/my_package/.venv/lib/python3.7/site-packages']

After removing the export, my sys.path was:

$ unset PYTHONPATH
$ cd src/my_package
$ source .venv/bin/activate
$python -c "import sys; print(sys.path)"
['', '/home/hodei/.pyenv/versions/3.7.7/lib/python37.zip', '/home/hodei/.pyenv/versions/3.7.7/lib/python3.7', '/home/hodei/.pyenv/versions/3.7.7/lib/python3.7/lib-dynload', '/home/hodei/src/my_package/.venv/lib/python3.7/site-packages', '/home/hodei/src/my_package/.venv/src/trading-ig', '/home/hodei/src/my_package']

Poetry always updates dependencies.

I have non root user pyuser.

Dockerfile example:

#...
USER pyuser

RUN pip install poetry==1.1.13 && poetry config virtualenvs.create false

#...

And poetry always updates installed dependencies.
