Some commands trigger KeyError after each change/commit

[pawamoy]

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

Exporting requirements Commands like pdm export or pdm install fail each time I commit something, or then change something, since it results in a different version for my current project (e.g. 0.24.2.dev7+g0ed9c36.d20221130). To fix the error, I have to lock again.

This issue is similar to #1288. However note that I don't depend directly on the current project, but rather indirectly. For example: current project is griffe, I specify mkdocstrings[python] in the docs deps, which depends on griffe.

Steps to reproduce

git clone https://github.com/mkdocstrings/griffe
cd griffe

export PYTHON_VERSIONS=3.10
make setup

make check-dependencies  # OK

echo >> README.md
make check-dependencies  # NOT OK

make lock
make check-dependencies  # OK AGAIN

Same thing with pdm install command:

rm pdm.lock
pdm install  # OK
echo >> README.md
pdm install  # NOT OK
pdm lock
pdm install  # OK AGAIN

Actual behavior

% pdm export -f requirements --without-hashes -v
The exported requirements file is no longer cross-platform. Using it on other platforms may cause unexpected result.

No key error 😄

Didn't have the chance to try master, but you released 2.3.0 in the meantime and it seems to be fixed. Thanks a lot!
