$ poetry lock

$ poetry lock --no-update

$ poetry lock --check

poetry lock [options]

poetry lock resolves all dependencies defined in pyproject.toml and writes the exact resolved versions to poetry.lock. This lock file ensures that every installation uses identical package versions for reproducible builds.
The --no-update flag regenerates the lock file format without updating dependency versions. The --check flag verifies that the existing lock file is consistent with pyproject.toml without modifying anything. Note that this command only updates the lock file; run poetry install afterward to actually install packages.

--no-update

Don't update dependencies.

Verify lock file is up-to-date.

Does not install packages. Run poetry install after.

poetry lock provides dependency locking for reproducible environments.
