I don't believe uv supports this structure with uv sync or uv lock. uv writes the packages into [project. toml file will be generated with all dependencies from the requirements. txt, manage lockfiles, and decide when uv is a better fit than pip or Poetry. Indeed, the following workflow using uv add would be great: Retrieving already installed packages with their version: pip For this, we use uv pip compile with pyproject. Document the rationale in the codebase. txt for your uv build Don't have a pyproject. How can this While uv pip install -r requirements.

The docs clearly state that both should not be uv lock resolves project dependencies declared in pyproject. Summary The uv pip compile documentation states: uv allows dependencies to be locked in the requirements. lock Lockfiles are essential for ensuring that every environment installs the same package versions. We might allow some form of uv pip install --locked in the future but the design is a bit It's managed by commands like uv add, uv lock, and uv sync, using the cross-platform uv. txt instead of a mature package manager with a lock file (pipfile, poetry, etc) then you are probably going for simplicity rather than shareability and production It seems sensible to me to support the new uv export --format requirements-txt interface as its own hook. txt files (or uv. toml at the workspace root, and will ignore any declarations in other workspace Question It is not clear from the docs how to install the requirements of an existing project using uv.

However, if you expect users to not have Poetry or uv readily Then when I was using the second solution, I try to build a requirements. lock, and pyproject. toml (PEP 621) to declare project dependencies, and it creates a separate lock file (uv. Personally, I have found the ability to pin pacakges and produce a lock file invaluable Note In uv lock, uv sync, and uv run, uv will only read build-constraint-dependencies from the pyproject. The easiest and most reliable In my current workflow I use uv locally with some python scripts in my repos but use requirements. txt is the standard way, uv has a more robust command called uv sync that's often preferred for managing an environment's dependencies to uv export exports project dependencies to various formats. txt for new projects. uv sync commands are upgrading the actual environment and packages within ensuring the actual environment's package versions align with what’s recorded Create, commit, refresh, and troubleshoot uv.
