uv doesnt update the package version when installed with uv pip install

[jzr-supove]

Summary

When I run uv add package-name, it installs an older version of the package unless I manually specify the version with uv pip install package-name==x.x.x. Why is that?

After updating the package version, how do I update the lock file? Shouldn’t it update automatically?
Running uv lock doesn’t seem to do anything, and uv sync reverts the package back to the old version listed in uv.lock.

At this point, I’m seeing more headaches than benefits compared to the standard venv + pip + requirements.txt workflow.

If the last version of package-name is incompatible with the other locked dependencies, a lower, compatible version is chosen. Can you try running with uv add --upgrade? This will also update the lockfile. By default, the lockfile only changes when necessary, to avoid churn and unrelated things breaking due to updates.
