Python 包管理器的终极指南:从零到精通

python A package manager is a tool for installing, managing and updating Python packages. They simplify the Python development process, eliminating the need for developers to manually manage dependencies.

Popular Python Package Manager

  • pip (pip install package): The most popular package manager, pre-installed on most Python installations.
  • conda (conda install package): An environment management tool that also includes a package manager for package management.
  • venv (python -m venv env): A virtual environment manager that separates packages from the system's installed Python.
  • poetry (poetry add package): A modern package manager that focuses on project dependency management and locking .

  • Isolate project dependencies: venv
  • Advanced project dependency management: poetry

Best Practices

  • Use virtual environments to isolate dependencies of different projects.
  • Update the package regularly to get security patches and new features.
  • Use a package locking file (such as Poetry's poetry.lock) to ensure that your dependency versions do not change unexpectedly.
  • Learn about the different package manager commands so you can troubleshoot them if needed.

in conclusion

The Python package manager is a key tool for improving development efficiency and keeping projects up to date. By understanding popular package managers and their usage, you can optimize your Python development process and create reliable, maintainable applications.
