UV 高级依赖

UV 项目高级依赖场景快速参考。

何时使用此技能

在以下情况使用此技能……	在以下情况改用针对性更强的同类技能……
将依赖项固定到 git URL、分支或标签，或以可编辑模式安装	添加常规 PyPI 依赖项——使用 uv-project-management
配置 [tool.uv.sources]、依赖组、额外依赖或自定义索引	在工作区成员之间共享源声明——使用 uv-workspaces
设置私有软件包索引或构建时约束	使用 --with 依赖项运行临时脚本——使用 uv-run

此技能适用的情况

• Git 仓库依赖项
• 本地路径依赖项
• 可编辑安装
• 依赖项约束
• 自定义软件包索引
• 依赖组和额外依赖
• 构建依赖项

Git 依赖项

# Add from Git repository
uv add git+https://github.com/psf/requests
uv add git+https://github.com/pallets/flask@main
uv add git+ssh://[email protected]/user/[email protected]

# Specific branch, tag, or commit
uv add git+https://github.com/user/repo@feature-branch
uv add git+https://github.com/user/[email protected]
uv add git+https://github.com/user/repo@abc123

路径依赖项

# Add from local path
uv add --editable ./local-package
uv add ../another-project
uv add /absolute/path/to/package

# Non-editable path
uv add --no-editable ./local-package

依赖组

# Add to named group
uv add --group docs sphinx mkdocs
uv add --group test pytest pytest-cov

# Install specific groups
uv sync --group docs
uv sync --group test --group docs

# Install all groups
uv sync --all-groups

额外依赖（可选依赖项）

# Install package with extras
uv add 'fastapi[all]'
uv add 'sqlalchemy[postgresql,mypy]'

# Define extras in pyproject.toml
[project.optional-dependencies]
dev = ["pytest", "ruff"]
docs = ["mkdocs", "mkdocs-material"]

约束文件

# Apply version constraints
uv pip compile requirements.in --constraint constraints.txt

# constraints.txt example:
# numpy<2.0
# pandas==2.0.3

自定义索引

[tool.uv]
index-url = "https://pypi.org/simple"
extra-index-url = [
    "https://custom.pypi.org/simple",
]

pyproject.toml 中的 Git 依赖项

[project]
dependencies = [
    "my-package",
]

[tool.uv.sources]
my-package = { git = "https://github.com/user/my-package" }

# With branch
my-package = { git = "https://github.com/user/my-package", branch = "main" }

# With tag
my-package = { git = "https://github.com/user/my-package", tag = "v1.0.0" }

# With commit
my-package = { git = "https://github.com/user/my-package", rev = "abc123" }

pyproject.toml 中的路径依赖项

[project]
dependencies = [
    "my-local-package",
]

[tool.uv.sources]
my-local-package = { path = "../my-local-package" }

# Editable (default for paths)
my-local-package = { path = "../my-local-package", editable = true }

# Non-editable
my-local-package = { path = "../my-local-package", editable = false }

依赖组

[dependency-groups]
dev = [
    "pytest>=7.0",
    "pytest-cov>=4.0",
    "ruff>=0.1.0",
]
docs = [
    "mkdocs-material>=9.0",
    "mkdocstrings[python]>=0.24",
]
test = [
    "pytest-asyncio>=0.21",
    "pytest-mock>=3.12",
]

URL 依赖项

# Add from direct URL
uv add https://files.pythonhosted.org/packages/.../requests-2.31.0.tar.gz

# In pyproject.toml
[tool.uv.sources]
my-package = { url = "https://example.com/my-package-1.0.tar.gz" }

私有软件包索引

[tool.uv]
# Primary index
index-url = "https://pypi.org/simple"

# Additional indexes
extra-index-url = [
    "https://${PRIVATE_TOKEN}@private.pypi.org/simple",
]

# Find links
find-links = [
    "https://download.pytorch.org/whl/cu118",
]

# Set token via environment
export PRIVATE_TOKEN="secret"
uv sync

构建依赖项

[build-system]
requires = [
    "setuptools>=68",
    "wheel",
    "Cython>=3.0",
]
build-backend = "setuptools.build_meta"

常见模式

从本地检出版本进行开发

# Clone dependency
git clone https://github.com/user/lib.git ../lib

# Add as editable
cd my-project
uv add --editable ../lib

单体仓库路径依赖项

[tool.uv.sources]
my-core = { path = "packages/core" }
my-utils = { path = "packages/utils" }

混合来源

[project]
dependencies = [
    "fastapi",          # PyPI
    "my-lib",           # Git
    "my-local",         # Path
]

[tool.uv.sources]
my-lib = { git = "https://github.com/user/my-lib" }
my-local = { path = "../my-local" }

解析策略

[tool.uv]
# Highest compatible (default)
resolution = "highest"

# Lowest compatible
resolution = "lowest"

# Lowest direct, highest transitive
resolution = "lowest-direct"
