PDM: Python 包管理工具

• Python 的包管理工具, 各有各的问题.
• 当前使用方案: pyenv + poetry. 基本够用.
• PDM, 之前看到过, 懒得尝试. (号称比 poetry 更好, 试试看)

Update: 2024-04:

• ✅ 更推荐 Rye, 已经比较成熟.
• ❎ 不推荐 PDM, 各种不完善 & bug.(始终不喜欢)

PK 其他:(试用报告)

• ✅ Poetry + Pyenv: 依然是当前(2023-12)首选.
• ❎ Rye: 当前不推荐, 和 Mojo 有干扰, 懒的排雷.(不如 poetry + pyenv)
• ❎ PDM: 不如 Poetry new project 方便, 虽然支持 pdm init --copier xxx 方式, 但不想用.
  • 亮点是 script 功能, 不过我重度使用 go-task, 也一样有.

PS:

• 💡 这些工具, 和 cargo(rust) 比, 都是半吊子, 各有各的残废.(还是别浪费时间了, 等 Mojo 吧)

PDM 安装:

• ✅ install pdm
• ✅ 推荐使用如下指令: 支持 pyenv.

pip install pipx
pipx install pdm[all]

• ❌ 不要使用:
  • ❌ 官方 curl -sSL https://pdm-project.org/install-pdm.py | python3 -
    • 无法和 pyenv 搭配.
  • ❌ brew install pdm
    • 会额外安装一堆一堆💩💩!!! (题外: brew 的依赖管理, 越来越恶心)

PDM 功能:

添加包依赖:

• https://pdm-project.org/latest/usage/dependency/

pdm add requests   # add requests
pdm add requests==2.25.1   # add requests with version constraint
pdm add requests[socks]   # add requests with extra dependency
pdm add "flask>=1.0" flask-sqlalchemy   # add multiple dependencies with different specifiers

# 本地包: 
pdm add ./sub-package
pdm add ./first-1.0.0-py2.py3-none-any.whl

# 基于 URL:
# Install gzipped package from a plain URL
pdm add "https://github.com/numpy/numpy/releases/download/v1.20.0/numpy-1.20.0.tar.gz"
# Install wheel from a plain URL
pdm add "https://github.com/explosion/spacy-models/releases/download/en_core_web_trf-3.5.0/en_core_web_trf-3.5.0-py3-none-any.whl"

dev 分组:

pdm add -dG test pytest

# 开发分组:
# A relative path to the directory
pdm add -e ./sub-package --dev
# A file URL to a local directory
pdm add -e file:///path/to/sub-package --dev
# A VCS URL
pdm add -e git+https://github.com/pallets/click.git@main#egg=click --dev

• 配置文件:

[tool.pdm.dev-dependencies]
lint = [
    "flake8",
    "black"
]
test = ["pytest", "pytest-cov"]
doc = ["mkdocs"]

PDM Script 功能: 🌟🌟🌟

• 这个不错, cargo 标配能力.
• https://pdm-project.org/latest/usage/scripts/

[tool.pdm.scripts]
start = {cmd = [
    "flask",
    "run",
    # Important comment here about always using port 54321
    "-p", "54321"
]}

PDM 创建项目:

• 基于模板方式.
• https://pdm-project.org/latest/usage/template/

pdm init --cookiecutter gh:cjolowicz/cookiecutter-hypermodern-python
# or
pdm init --copier gh:pawamoy/copier-pdm --UNSAFE
