Pip 正在集成到 Linux repository 中​

现在 再使用 pip install 可能会 提示以下消息

error: externally-managed-environment

× This environment is externally managed
╰─> 
    The system-wide python installation should be maintained using the system
    package manager (apk) only.
    
    If the package in question is not packaged already (and hence installable via
    "apk add py3-somepackage"), please consider installing it inside a virtual
    environment, e.g.:
    
    python3 -m venv /path/to/venv
    . /path/to/venv/bin/activate
    pip install mypackage
    
    To exit the virtual environment, run:
    
    deactivate
    
    The virtual environment is not deleted, and can be re-entered by re-sourcing
    the activate file.
    
    To automatically manage virtual environments, consider using pipx (from the
    pipx package).

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

你可能需要 将 pip install somepackage 替换为 apk add py3-somepackage (Alpine Linux).

其实这是一个好消息

  1. python 的包本身就是安装到系统的某个目录中，而不是安装到项目目录中。系统软件包接管 这很合理。
  2. 对于国内这样的糟糕的网络，镜像站则是必须的，对于 pip 来说，可以少设置一层 镜像或代理，而且多亏了这些镜像站，速度非常的快。
