Cannot install in docker

• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

Use a docker file to install pdm and bring the project to production.

Docker file :

FROM archlinux

# Init package manager keyring
RUN pacman-key --init 
# Update and basic development tools (gcc etc...)
RUN pacman -Syu --noconfirm --quiet  
RUN pacman -S --noconfirm --quiet base-devel  

# Create a project folder
RUN mkdir /python-nlu
WORKDIR /python-nlu

# Copy all project files (including pyproject.toml)
COPY . /python-nlu
RUN mkdir -p models/nlu

# Install the python dependency and python project 
RUN pacman -S --noconfirm --quiet git
RUN pacman -S --noconfirm --quiet python-pip python-setuptools python-wheel 
# Can also run pip install setuptools wheel instead
RUN pip install pdm 
RUN pdm install # Crashes here (or any other pdm related command with the same error)
CMD ["pdm", "run", "server"]

Actual behavior

Getting a

Traceback (most recent call last):
  File "/usr/sbin/pdm", line 5, in <module>
    from pdm.core import main
  File "/usr/lib/python3.9/site-packages/pdm/__init__.py", line 6, in <module>
    from pdm.core import Core
  File "/usr/lib/python3.9/site-packages/pdm/core.py", line 16, in <module>

    from pdm.resolver import resolve
  File "/usr/lib/python3.9/site-packages/pdm/resolver/__init__.py", line 1, in <module>
    from pdm.resolver.core import resolve  # noqa

    _old_merge_into_criterion = Resolution._merge_into_criterion
AttributeError: type object 'Resolution' has no attribute '_merge_into_criterion'

Note that pdm install works locally on my machine (which is also on archlinux).

Expected behavior

Build the image without problems and run pdm in a container

Environment Information

Cannot run pdm info or other pdm related command as it leads to the same error (shown above)

Note that I need the archlinux image as I’m also installing tools (like java, llvm10), etc… so I cannot use the official pdm image.

I suspect that the pip version was updated and pdm isn’t working with the new one maybe something like https://github.com/pypa/pip/issues/9188

[frostming]

It is because PDM is patching an internal class of resolvelib and is broken by the new release of resolvelib. A bugfix release will soon be out. As a workaround, you can pin the resolvelib version by:

pip install resolvelib==0.7.0 pdm

[ierezell]

My bad, I copy-pasted the above comment with resolvlib 1.7.0 (I should’ve double-checked). I replaced it with 1.7.1

I did a fresh install by removing __pypackages__ and pdm.lock was it the “fresh” you intended ? I also have them in my .dockerignore so they’re not copied. Also did a docker system prune -a

It works except that I’m stuck in either an infinite dependency resolving loop or get the AttributeError: 'JoinedStr' object has no attribute 's' error from above.

here is my dependency list if you want to try to reproduce (the only constrain is on torch):

"torch==1.8.0", # To make pdm able to install it (latest is 1.9)
"transformers", # need torch
"torchaudio", # need torch
"spacy-transformers", # dependency loop as it need torch 
"uvicorn",
"uvloop",
"faiss-cpu",
"rich",
"fastapi",

Thanks again for your precious time ! Have a great day
