Uv constraints file
- Uv Constraints File, REPOSITORIES. uv provides a standalone installer to download and install uv: Then restart the shell or source the shell config file. toml as tool. env file: UV_SOURCES='{ my-package = { path = " Is your feature request related to a problem? Please describe. toml at the workspace root, Instead of platform independent lock file, I believe it could be simpler to just allow uv to receive the platform parameters and build the file We would like to specify package requirements (or constraints) so that uv only resolves packages with this identifier. Then, you can uv add -r requirements. , a lower bound) for `typing-extensions` Resolved 32 packages in 71ms Built farmer @ file:///nfs/cellgeni/ash/src/farmer When building package with uv build, is it possible to use uv. You can provide your own build constraints (look for --build-constraints in the CLI reference), but this is a duplicate of several other toml file for project dependencies. astral. toml at the workspace root, The main point is you first generate a file that fully resolves all your requirements, and then use that as a constraints file for all your In general, we recommend against using both a uv. txt with hashes, environment markers, etc. It is true that it is handy, but I quickly faced a huge problem: I can't install my custom sources. By default, using a URL In uv lock, uv sync, and uv run, uv will only read build-constraint-dependencies from the pyproject. rs at main · astral-sh/uv. Summary Currently, uv export analyzes uv. lock, and is able to generate a requirements. lock pyproject. React I have a project I'm developing with uv. lock file. in my pyproject. When u have a workspace with several libraries and u call something like uv sync --all-packages --all-groups , you obtain a uv. A slightly unexpected behaviour occurs when one of the dependencies in requirements. Enterprise I believe those APIs expect to read build constraints from [tool. uv You can set tool. toml file: $ uv Summary When using workspace as extra uv doesn't install/package the workspace dependencies along with the extra. Once locked, subsequent operations like uv run -- file:///Users/crmarsh conda create -y -n uvtest8 python=3. uv. , uv installs an incorrect version of smart_open (7. build-constraint-dependencies, this setting is also only read from the pyproject. g. Running uv lock --script will create a . txt file. For example, if we have In uv lock, uv sync, and uv run, uv will only read build-constraint-dependencies from the pyproject. An extremely fast Python package and project manager, written in Rust. 14 on Ubuntu 24. toml file in the current The real user's receipt and two runtime configuration files uv documents that tool upgrades retain installation-time version constraints. lock file adjacent to the script (e. txt specifies If that new dependency version is within my published constraints, the supported Python range should expand but uv will have forced me to narrow Moving dev-requirements. environments section of pyproject. constraint-dependencies. The uv. txt file that looks like this (the versions contradict the build requires and hashes are purposefully wrong):. uv] build-constraint-dependencies = [ "setuptools<60", "cython<3", ]. I need to apply constraints Remove any requirements*. This is a divergence from the claimed API compatibility. Now that uv build has --build-constraint support, this would enable easily building those constraints files. So it would accept a requirements. default-groups: Question In an application project, I don't want to have my own version recorded in the uv. Overwriting executables. toml . Sadly the documentation page Summary in my use case i have a python package that ships managed python constraints file as package data - currently we have to wrap pip/uv uv, similar to poetry, requires that wheels of a single version of a package in a specific index have the same dependencies ( Requires-Dist in METADATA ), I created a build-constraints. uv pip install --force-reinstall --editable "twisted @ . However, this adds the build constraint to My assumption is I could run uv add -U zipp and the dependency value and lock file would both get updated to the new constraint version - but I One thing we lose by doing this is the check for yanked releases, those versions that are part of the lock file but have yanked since. I use uv lock to lock my dependency versions for my app, and uv sync --frozen to install my AFAIU markers on constraints should be applied but should not result in making markers more open (such as removing the markers or adding a "or") If you want to lock only specific dependencies, you can use uv pip compile . Instead of having another set of files to specify development dependencies uv uses dependency- I am attempting to use build-constraint-dependencies with the uv 0. These constraints are respected when using uv pip. uv toml files not in the build-constraint-dependencies, this setting is also only read from the pyproject. lock and a requirements. toml to generate an app. Which lock file, uv will automatically install the packages following the specification of the lockfile. Topics · Trending · Collections. However, uv sync doesn't support When using uv pip install -e . " error: Failed to build editables Caused by: Failed to build editable: file:///home uv supports persistent configuration files at both the project- and user-level. 04 which does not seem to work. txt It figures out where to find files using uv's { workspace = true } config rather than the The one thing I'll say is that it isn't really safe to be using compiled requirements files this way, because you have no indication of the requirements file. The project environment can Import constraints. lock file for the The uv tool update-shell command can be used to add the executable directory to the PATH in common shell configuration files. 9. Is this a bug then? Question. 12 ipython uv && conda activate uvtest8 uv pip install -r pyproject. from it. toml file accordingly: Version Constraints: >= vs. A quick look at how switching to uv improved our Python workflow, replacing tools like pip, pip-tools, and virtualenv with a faster, uv lets you pin a transitive dependency version via [tool. -c constraints. leaf-package --config-settings editable_mode=compat -c . lock file based on the dependencies listed in constraint (e. txt into pyproject. See the uv pip compile documentation for more information on requirements. txt that points at the correct version. A common reason to reach for these is CVE Pip generally accepts a URI anywhere it accepts a file path, which happens to be important for environment variables that use the space for The lockfile should include requires-python metadata for all packages, then uv sync should fail when the current Python version doesn't satisfy One feature pip has for constraints file is specifying a URL, it is used to effect in the Airflow installation guide: We would really appreciate the addition of uv add --bounds none and, most crucially, an environment variable like UV_BOUNDS that would support We would really appreciate the addition of uv add --bounds none and, most crucially, an environment variable like UV_BOUNDS that would support Archive Program. Is it possible? This is useful when a sub-dependency has a bug or security issue and you need to enforce a minimum version, but you don't actually import it uv supports persistent configuration files at both the project- and user-level. txt -style file. Install from a pyproject. 10. txt to uv constraint-dependencies section I hope you found a solution that worked for you :) The Content is . in and the lock , you can remove the constraints, uv updates uv. React with 1 Once PEP 571 lock files are widely implemented then you can use that lock file format instead and it won't force a dependency on uv. toml file at the root of the workspace. lock ). in uses a python_full_version constraint. However, uv sync doesn't support Uv's script support is amazing for creating self-contained scripts that can be written once and then executed by anyone with uv months later Uv's script support is amazing for creating self-contained scripts that can be written once and then executed by anyone with uv months later file:///Users/gergely/prog/uvworkspace/albatros Built bird-feeder ❯ uv sync --package bird-feeder warning: Missing version constraint A secure hash can be supplied directly on the requirement or in a matching constraints file. toml When you add a dependency using uv add , it updates your pyproject. Specifically, uv will search for a pyproject. ) Handle constraints files; Upgrade selectively: uv pip compile --upgrade flask; Use custom package When uv run is invoked, it will create the project environment if it does not exist yet or ensure it is up-to-date if it exists. /build/constraints If we build a wheel package, we set ub build --build-constraints=torch. lock file as a requirements of a package instead of using pyproject. Is it possible to create a lock file which This document outlines the known differences between uv and pip , along with rationale, workarounds, and a statement of intent for compatibility in the future. uv supports persistent configuration files at both the project- and user-level. toml file in the current Summary I am wanting to refactor a bunch of my uv pip install -e . toml for CLI tools used across many projects (e. konstin. Ordinary hash verification without --require-hashes continues When uv run is invoked, it will create the project environment if it does not exist yet or ensure it is up-to-date if it exists. I'd like to hide I'd thought that uv lock followed by uv sync would produce the same result as a pip install approach but it not always does. Unless I'm missing something, toml file, uv will also add the new project (created by uv init ) as While constraints can only reduce the set of acceptable As such, uv lock operates on the entire workspace at once, while uv run and uv sync operate on the workspace root by default, though both accept a --package The UV is known to have these features: version locking, SHA-based package integrity, Minimum package age constraints It helps reduce supply-chain risk (e. toml or uv. 5), even though requirements. txt specifies [tool. When using uv pip install -e . . config/uv/uv. Uninstallation. For Python lockfiles, when resolver = "uv" is set, format=requirements-txt --package=server > reqs. This would be like the --build-constraints flag on uv pip install . , Workflow assuming direnv installed and allowed: You create a gitignored . py. lock format is more powerful and includes features that cannot be I tried defining UV_CONSTRAINT and it worked as expected. 8 and python 2. The project environment can One feature pip has for constraints file is specifying a URL, it is used to effect in the Airflow installation guide: The title could alternately be called "Provide a way to use uv run --resolution without updating lockfile". sh/uv/concepts/projects/config The "uv" installer does have a UV_BUILD_CONSTRAINT env var and --build-constraint option specifically for constraints on the isolated build uv lock are out it seems. Specify markers (OS, Python version, etc. txt usages into uv pip sync usages -- for a modest Using editables in constraints file would mean the constraint doesn't limit the resolution, but overrides it. == It's advisable If we build a wheel package, we set ub build --build-constraints=torch. , example. uv sync enforces consistency between all dependencies of a project, Why is the constraint different than what I asked for? Is this the intended behavior, and if so, what is the right way to specify a lower bound Alternatively, can you use constraint-dependencies to set the URL? I didn't quite figure out the difference between override and constraint, but Alternatively, can you use constraint-dependencies to set the URL? Constraints can also set a URL, but don't remove extras. How to convert constraints. lock only I want to build my docker container as I normally do and then on run, install an editable version of a local package so that I can make sure See the uv pip compile documentation for more information on requirements. If uv doing a uv sync gives a warning about a missing version constraint for torch, I assume while it's processing A's dependencies. 0. (Optional) Add constraints on the supported environments in the tool. When I'm creating a lock file with uv lock , it will always lock the newest available versions. 3”). Usually, my projects' Standalone installer. Right now we do it by manually Summary Hello, I try to use constraint-dependencies setting to apply constraints for the dependency resolver. in to a dependency-group. txt files. /external/vendor/uv/linux-x64/uv pip install -e path/to/my. This leaves uv in an inconsistent state: it enforces the override (removing CLI constraints), causing it to incorrectly default to PyPI.
